Why the Alamo 15 Trigger Has Everyone Talking
The Alamo 15 is not your average drop-in trigger replacement. It is a positive displacement trigger — a technology that has been decades in the making — designed to reset faster than anything else on the AR-15 market. Shooters who have switched to it describe the experience as transformative. The split times get faster. The accuracy holds up even at speed. And the trigger pull itself feels completely different from the gritty, heavy mil-spec trigger most AR-15s ship with.
But before you buy, there is a lot you should know. What exactly is the Alamo 15? Who made it and why does that matter? How does it work differently from a standard trigger or a binary trigger? What does the law say about it? And how do you install it correctly?
What Is the Alamo 15 Trigger?
The Alamo 15 Trigger, sold under the brand name Powered by Graves (PBG), is a positive displacement drop-in trigger system for the AR-15 platform. It is designed specifically for AR-15 and AR pistol builds chambered in .223 Remington and 5.56 NATO.
At its core, the Alamo 15 is a type of forced reset trigger (FRT) — but with a critical distinction. Unlike some other FRT designs on the market, the Alamo 15 uses what is called positive displacement technology, backed by a patent held by the trigger’s original inventor, Thomas Allen Graves.
When you fire a round, the Alamo 15’s mechanism uses the energy of the cycling bolt carrier group to physically push the trigger forward and reset it. This happens almost instantaneously — faster than your finger can consciously release the trigger. The result is that by the time you are ready to pull the trigger again, it is already reset and waiting for you. The gap between shots shrinks dramatically.
The Alamo 15 is not a fully automatic trigger. It fires one round per trigger pull, just like any standard semi-automatic trigger. What changes is how fast and how smoothly the trigger gets back to the ready position after each shot. That mechanical advantage is what makes the Alamo 15 such a standout upgrade.
The Man Behind the Trigger: Thomas Allen Graves
One of the most compelling things about the Alamo 15 Trigger is the story behind who created it.
Thomas Allen Graves is the original designer and patent-holder of the positive displacement reset trigger. His development of this technology spans more than 40 years of research and development — making him one of the longest-tenured minds in the specialized field of rapid-reset trigger engineering.
Graves did not create a knock-off or a copy of someone else’s design. He is the originator. The concept of using the firing cycle’s own mechanical energy to positively displace — push forward — the trigger group goes back to his foundational patents. Other forced reset triggers on the market operate on related principles, but the Alamo 15, sold under the Powered by Graves brand, represents Graves’ most refined and current expression of this technology.
That history matters. When you buy the Alamo 15 Trigger, you are not buying a product rushed to market. You are buying the latest version of a design that has been tested, refined, patented, and developed by its original inventor over four decades. That is a rare thing in any product category, let alone in the fast-moving world of AR-15 accessories.
The Graves Roller Technology: What Makes It Different
The technical heart of the Alamo 15 Trigger is what Powered by Graves calls the Graves Roller Technology — a patented design feature that sets it apart from other forced reset triggers.
Here is what that means in practical terms.
Most trigger mechanisms — including many other FRT designs — use components that slide forward and backward against each other during the reset cycle. Buy Alamo 15 Trigger . this sliding friction creates wear over time. The more rounds you fire, the more these components wear down. Eventually, that wear can affect reliability and consistency.
The Graves Roller Technology replaces that sliding contact with a roller-based locking bar. Instead of components scraping across each other, the roller pivots — it moves up and down rather than forward and backward. This dramatically reduces friction at the critical contact point during reset.
The benefits of this approach are significant:
- Less wear and tear on the trigger components and the bolt carrier group
- More consistent reset cycle after cycle because the mechanics stay cleaner
- Longer service life for the trigger assembly
- More reliable cycling because the reset mechanism does not degrade as quickly under sustained use
This is not just a marketing claim. Users who have put thousands of rounds through the Alamo 15 report that it continues to feel consistent and smooth even with significant round counts, which is a strong indicator that the roller technology genuinely reduces wear the way Powered by Graves says it does.

Key Features of the Alamo 15 Trigger
Let us go through each of the Alamo 15’s standout features in plain language so you know exactly what you are getting.
1. Positive Displacement Reset
This is the defining feature. After each shot, the trigger is mechanically pushed forward by the cycling BCG — not by your finger releasing it. This means the trigger is reset and ready before you even consciously think about your next pull. For competitive shooters, this can shave meaningful time off split times between shots.
2. Patented Graves Roller Technology
The hardened 440-C steel roller locking bar replaces sliding-friction contact with rolling motion. Less friction means less wear on both the trigger assembly and the bolt carrier group. The trigger runs smoother for longer.
3. Hardened 17-4 Stainless Steel Hammer
The hammer is one of the highest-stress components in any trigger group. By making it from hardened 17-4 stainless steel — a material known for its excellent hardness, corrosion resistance, and strength — Powered by Graves ensures the Alamo 15 holds up under heavy use. Buy Alamo 15 Trigger
4. Smooth Pull and Crisp Break
Beyond the speed of reset, the Alamo 15 delivers a noticeably better trigger pull than a standard mil-spec trigger. Users consistently describe the break as crisp and clean — the moment of firing is clear and predictable, which is critical for accuracy.
5. Adjustable Pull Weight
The Alamo 15 offers adjustable trigger pull weight, allowing shooters to customize the amount of force required to fire. Whether you prefer a light 3.5 lb pull for competition use or a slightly heavier 4.5 lb pull for more deliberate shooting, the Alamo 15 can be tuned to your preference.
6. Anti-Walk Pin Design
A common problem with aftermarket triggers is that the trigger and hammer pins can slowly “walk” out of their pin holes during firing, eventually causing the trigger to fail. The Alamo 15 comes with an anti-walk pin design that locks the pins in place and eliminates this issue entirely.
7. Drop-In Installation
The Alamo 15 is a drop-in trigger that installs into any standard mil-spec AR-15 lower receiver without permanent modifications, special tools, or gunsmithing. If you can field-strip your AR-15, you can install the Alamo 15.
8. Included Hardware
Unlike some trigger upgrades that ship as trigger components only, the Alamo 15 ships with all the necessary hardware for installation, including the anti-walk pins. You have everything you need right in the box.
How the Alamo 15 Trigger Works
Understanding the mechanics helps you appreciate what makes this trigger special and also helps you install and troubleshoot it correctly. Buy Alamo 15 Trigger
Here is what happens inside your rifle when you pull the Alamo 15 Trigger:
Step 1 — Trigger Pull: You pull the trigger rearward. The sear releases the hammer, which swings forward and strikes the firing pin. The firing pin ignites the primer. The round fires.
Step 2 — BCG Travels Rearward: Gas pressure from the fired round pushes the bolt carrier group rearward. As the BCG moves back, it ejects the spent case and cocks the hammer.
Step 3 — Positive Displacement Reset: Here is where the Alamo 15 differs from a standard trigger. As the BCG travels rearward, it contacts the Alamo 15’s Graves Roller mechanism. The roller — using the BCG’s own kinetic energy — pushes the trigger forward, completing the reset mechanically and nearly instantaneously.
Step 4 — BCG Returns Forward: The BCG moves forward under spring pressure, stripping a new round from the magazine and chambering it. By the time the BCG returns to battery, the trigger has already been reset.
Step 5 — Ready for the Next Shot: The trigger is already at its reset point, waiting for your next pull. You do not have to consciously release the trigger to achieve reset — it happened automatically during the BCG cycle.
The result of this process is that a trained shooter can fire the Alamo 15 at a dramatically faster rate than a standard semi-automatic trigger allows, while still firing exactly one round per trigger pull. Control remains entirely in the hands of the shooter.
Who Should Buy the Alamo 15 Trigger?
The Alamo 15 is an excellent trigger, but it is not the right choice for every shooter or every application. Here is an honest assessment of who will benefit most from this upgrade.
Best Suited For:
Competitive Shooters — If you compete in action shooting sports, three-gun competitions, or any discipline where split times matter, the Alamo 15 gives you a real, measurable edge. Faster reset directly translates to faster strings of fire with consistent accuracy.
Experienced AR-15 Owners — The Alamo 15 rewards shooters who already have good trigger discipline and a solid foundation with their AR-15. The faster reset amplifies the skills you already have.
Range Enthusiasts Who Want the Best Experience — Putting rounds downrange with the Alamo 15 is genuinely more enjoyable than with a mil-spec trigger. The smooth pull, crisp break, and instant reset combine for a shooting experience that mil-spec simply cannot match.
Shooters Who Have Used Binary Triggers — If you have enjoyed binary triggers but find them awkward (fire on release, legal complications in some states), the Alamo 15 offers similar excitement — fast, controlled rapid fire — without the release-fire element. You stay entirely in semi-automatic territory.
Hunting and Target Shooting — For hunters who need fast follow-up shots on game, or target shooters looking to tighten their groups through a more consistent trigger pull, the Alamo 15’s crisp break and smooth pull offer genuine accuracy benefits even at standard shooting speeds.
May Not Be Ideal For:
First-Time AR-15 Owners — Learn the basics of your platform before adding a rapid-reset trigger. The faster reset can encourage rushing shots if you have not yet developed proper trigger discipline.
Precision Long-Range Shooters — The Alamo 15 is a speed-optimized trigger. If your primary use is 400–1000 yard precision shooting where trigger weight, zero creep, and overtravel are the priority, a dedicated single-stage or two-stage match trigger from a specialist company will serve you better. Buy Alamo 15 Trigger
Home Defense Configurations — In a defensive scenario, a trigger that resets this fast requires very deliberate trigger control under stress. For a dedicated home defense firearm, a standard quality trigger is generally the more appropriate choice.
Suppressor Builds — The Alamo 15 can work with suppressors, but it requires careful tuning of the buffer and gas system. Suppressors increase back-pressure, which affects cycling speed. If you run a suppressor, plan to spend time tuning the setup before relying on it.
Alamo 15 vs. the Competition: How Does It Stack Up?
The Alamo 15 Trigger competes in the growing market of assisted-reset and forced reset triggers for the AR-15. Here is how it compares to the main alternatives.
Alamo 15 vs. Standard Mil-Spec Trigger
There is no comparison in terms of performance. A standard mil-spec trigger typically has a heavy, gritty pull (5.5–8 lbs in many cases), significant creep, and a long, unpredictable reset. The Alamo 15 offers a smooth pull, a crisp break, an adjustable pull weight, and an instant mechanical reset. The improvement is dramatic and immediately noticeable. The only advantage of mil-spec is cost — a standard trigger is much cheaper. But as an upgrade, the Alamo 15 represents a worthwhile long-term investment.
Alamo 15 vs. Standard Match Triggers (Geissele, Timney, TriggerTech)
Standard match triggers from respected brands like Geissele, Timney, and TriggerTech offer excellent trigger pull quality — light, crisp, and consistent. They are excellent choices for accuracy-focused shooting. However, they do not offer the rapid mechanical reset of the Alamo 15. If your goal is pure shooting accuracy, a Geissele SSA or TriggerTech Diamond may be equally appropriate. If your goal is fast follow-up shots combined with a quality trigger pull, the Alamo 15 is in a different performance category.
Alamo 15 vs. Binary Triggers (Fostech Echo Sport, Franklin Armory)
Binary triggers fire on both pull and release, doubling the shots per trigger cycle. This is extremely fast but comes with complications: they are banned in many states, they require specific technique for the release-fire element, and they fire one round when you may not intend to (the release shot). The Alamo 15 does not have these complications — it remains strictly semi-automatic (one round per pull) while still offering dramatically faster reset than standard triggers. For many shooters, the Alamo 15 is the better choice because it is faster than standard without any of the binary trigger’s complexities.
Alamo 15 vs. Other FRT Triggers (Rare Breed FRT-15, Partisan Disruptor)
The Rare Breed FRT-15 and Partisan Disruptor are other forced reset triggers with strong reputations. The key distinguishing feature of the Alamo 15 is the Graves Roller Technology — the pivot-based roller locking bar that reduces wear and extends reliability. The Alamo 15 also benefits from the original inventor’s backing. Pricing across these options is broadly similar ($200–$400), so the choice often comes down to the specific design you prefer and which product is in stock when you are ready to buy.
Legal Status of the Alamo 15 Trigger
The legal status of forced reset triggers like the Alamo 15 has gone through significant changes in recent years. Here is the complete picture as of 2026.
Federal Law: Now Legal
For several years, the ATF took the position that forced reset triggers were machine guns under the National Firearms Act (NFA) because they allow dramatically faster firing rates. This led to enforcement actions, seizures, and ongoing litigation.
The legal landscape shifted in 2024 when the U.S. Supreme Court ruled 6-3 in Garland v. Cargill — a case involving bump stocks — that devices which require a separate, deliberate trigger function for each shot fired do not constitute machine guns under the statutory definition of the NFA. A machine gun fires continuously with a single trigger pull; the Alamo 15, like all properly designed FRT triggers, fires exactly one round per trigger pull.
Following that ruling, a U.S. District Court in the Northern District of Texas applied the same reasoning directly to FRT triggers, ruling in July 2024 that forced reset triggers are not machine guns under federal law.
The Department of Justice settled its remaining FRT litigation in May 2025, formally ending federal enforcement against the possession and transfer of forced reset triggers. As of mid-2026, the Alamo 15 Trigger is federally legal. It is not an NFA item. No tax stamp is required. No special registration or licensing is needed. It ships like any other firearm accessory.
State Laws: Know Your Local Rules
Federal legality does not equal universal legality. Many U.S. states maintain their own restrictions on devices that increase semi-automatic firing rates, and these state laws are independent of the federal settlement.
As of 2026, FRT-type triggers are restricted or prohibited in several states including (but not limited to):
- California
- Connecticut
- Delaware
- Hawaii
- Illinois
- Maryland
- Massachusetts
- New Jersey
- New York
- Oregon
- Rhode Island
- Washington State
- Washington D.C.
This list can change. State laws around firearm accessories are an active legislative area. Always verify your state and local laws before purchasing the Alamo 15 Trigger. Reputable dealers verify shipping addresses for compliance before completing sales.
This guide does not constitute legal advice. If you have questions about FRT trigger legality in your specific state, consult a licensed firearms attorney.
How to Install the Alamo 15 Trigger
Installing the Alamo 15 Trigger is a drop-in process that most AR-15 owners with basic mechanical comfort can handle in under 20 minutes. Here is a thorough walkthrough.
Before You Start: Safety First
Always confirm your firearm is completely unloaded. Remove the magazine. Lock the bolt back and visually inspect the chamber. Do this twice. Never work on a loaded firearm.
Tools You Will Need
- AR-15 lower receiver vise block or armorer’s block
- Punch set (3/32″ and 1/8″ punches)
- Hammer
- Needle-nose pliers (for spring management)
- Quality gun lubricant or CLP
- Torque wrench (optional but helpful)
Step 1 — Separate Upper and Lower
Push out both takedown pins and separate the upper receiver from the lower. Set the upper aside.
Step 2 — Secure the Lower
Place the lower receiver in your armorer’s block or vise block to hold it steady during work.
Step 3 — Remove the Existing Trigger Group
Using a 3/32″ punch, drive out the trigger pin from right to left. Remove the trigger and disconnector. Then drive out the hammer pin and remove the hammer. Set aside any springs you may want to keep as spares.
Pro Tip: Take a photo of your existing trigger group before removal so you have a reference if you ever need to reinstall the stock components.
Step 4 — Prepare the Alamo 15 Assembly
Lay out all the components from the Alamo 15 package. Apply a very light coat of quality gun lubricant to the trigger pin, hammer pin, and the roller contact surfaces on the trigger assembly. Do not over-lubricate — excess oil attracts carbon fouling.
Important: Do not pull the trigger while the assembly is outside the lower receiver. This can cause internal components to shift or spring free.
Step 5 — Install the Trigger
Lower the Alamo 15 trigger assembly into the trigger pocket of the lower receiver, aligning the trigger pin holes. Install the included anti-walk trigger pin from the right side. Push it through until it is flush with both sides of the lower receiver.
Step 6 — Install the Hammer
Place the hammer into position with the hammer spring legs positioned correctly on either side of the trigger pin (this is standard AR-15 hammer installation). Install the anti-walk hammer pin.
Step 7 — Install the Selector
The Alamo 15 works with a standard two-position (Safe/Fire) AR-15 safety selector. Reinstall your existing selector if you removed it, or leave it in place if it was not disturbed.
Step 8 — Function Check
Before reassembling, perform a complete function check:
- Safe position: Set the selector to Safe and pull the trigger. The trigger should not move.
- Fire position: Move to Fire and pull the trigger. The hammer should fall. Hold the trigger rearward, manually cock the hammer (using your thumb to simulate the BCG cycling). You should feel the disconnector catch the hammer. Release the trigger slowly — you should feel and hear a click as the trigger resets. Pull the trigger again — the hammer should fall.
If the trigger does not reset or the hammer does not fall properly, do not reassemble. Review the installation against the manufacturer’s instructions and watch the Powered by Graves installation video.
Step 9 — Reassemble and Live-Fire Test
Reassemble the upper to the lower. Take the rifle to a range with quality brass-cased .223/5.56 ammunition and test-fire at least 20 rounds before any extensive use. Listen and feel for consistent reset and confirm reliable function before trusting the trigger for any serious application.
Hardware Requirements: What Your Rifle Needs
The Alamo 15 Trigger has specific hardware requirements that are critical for reliable operation. If your rifle does not meet these requirements, the trigger may not function correctly.
M16-Profile Bolt Carrier Group (BCG)
The Alamo 15’s positive displacement mechanism relies on the M16-profile (full-auto cut) BCG to make contact with the Graves Roller during the rearward stroke. A standard AR-15 profile BCG has a different geometry that may not consistently engage the reset mechanism.
Most current production AR-15s ship with an M16-profile BCG already installed — but this is worth confirming. Running an M16-cut BCG in a semi-auto AR-15 is completely legal in all 50 states.
H-2 or Heavier Buffer
The Alamo 15 requires a minimum of an H-2 buffer (approximately 4.7 oz). The manufacturer also recommends H-3 for many builds. The standard carbine buffer (3 oz) is too light for reliable operation with this trigger.
A heavier buffer slows the rearward travel of the BCG slightly, which gives the reset mechanism the right timing to function correctly. Too light a buffer causes over-cycling; too heavy prevents proper cycling. H-2 or H-3 covers the vast majority of builds. For short-barreled rifles and suppressed setups, H-3 and a flat wire spring are commonly recommended by users.
Mil-Spec Lower Receiver
The Alamo 15 is designed for a standard mil-spec lower receiver. If you are using a non-standard or significantly modified lower, confirm compatibility before purchase.
What Real Users Are Saying: Alamo 15 Trigger Reviews
One of the most reliable ways to evaluate any product is to hear from people who have actually used it. Here is a summary of what verified Alamo 15 Trigger owners are consistently reporting:
The Overwhelming Positives
The single most common theme across user reviews is sheer shooting enjoyment. People who install the Alamo 15 describe the experience as transformative compared to their previous trigger. The smooth pull and instant reset combine to make rapid semi-automatic fire feel effortless and controlled in a way that is hard to describe until you feel it yourself.
Accuracy improvements are a consistent secondary theme. Many users note that their shot groupings tightened after switching to the Alamo 15 — not just because the trigger pull is lighter and crisper, but because the predictable, consistent break helps them maintain better sight picture through the shot.
The drop-in installation process earns high marks. Reviewers describe the installation as straightforward, with clear instructions, and many complete it in under 20 minutes even on their first attempt.
One verified owner summarized the experience well: the Alamo 15 takes an AR-15’s trigger pull from feeling like dragging a finger through gravel to operating on silk. That leap in feel quality is consistently reported across user reviews.
The Honest Criticisms
Price is the most common criticism. At $200–$300, the Alamo 15 costs significantly more than a standard trigger replacement and more than many quality match triggers. Users who feel it is worth it typically say so emphatically — but the upfront cost is real and worth budgeting for.
Ammo sensitivity comes up. Some users note that the trigger runs best with quality brass-cased .223/5.56 ammunition and may experience occasional reset issues with steel-cased budget ammunition like Wolf or Tula. This is common with any precisely toleranced trigger mechanism and is generally solved by sticking to quality ammo.
The buffer requirement catches some buyers off guard. If your rifle has a standard carbine buffer, you will need to purchase an H-2 or H-3 buffer separately to run the Alamo 15 reliably. Factor this into your total purchase budget.
Short-barreled AR pistol builds require more tuning patience. The Alamo 15 can work in SBR and AR pistol configurations, but getting the buffer and gas system dialed in takes more effort than in a standard 16″ carbine configuration.
Troubleshooting Common Alamo 15 Issues
Even a quality trigger can have hiccups if the supporting hardware is not right or if maintenance is overdue. Here are the most common Alamo 15 issues and their solutions.
Trigger Not Resetting: The most common cause is an incorrect buffer. Confirm you are running an H-2 or heavier buffer. Also check that the roller locking bar is properly lubricated — a dry roller can cause inconsistent reset. Confirm your BCG is M16-profile.
Light Primer Strikes: This usually indicates the BCG is cycling too slowly and not building enough energy to fire the primer reliably. Try a slightly lighter buffer (within the H-2 minimum range) or ensure your gas system is not under-gassed. Confirm you are using quality brass-cased centerfire ammunition with standard primer sensitivity.
Double-Fire or Uncontrolled Fire: Stop shooting immediately and do not continue until the issue is resolved. This type of malfunction should be inspected by a qualified gunsmith. Do not attempt to continue using the trigger if it is firing more than one round per trigger pull.
Heavy or Gritty Trigger Feel: Clean and lightly lubricate the trigger assembly, paying particular attention to the roller contact surfaces. Carbon buildup on the BCG and inside the lower can affect trigger feel over time.
Anti-Walk Pins Coming Loose: Confirm the pins are properly seated and fully driven through the lower receiver. If they continue to walk, a small amount of thread-locking compound (such as blue Loctite) applied carefully to the pin ends can help, but this should be done sparingly.
Tips for Getting Maximum Performance From Your Alamo 15
Once your Alamo 15 is installed and running reliably, these tips will help you get the most out of it:
Use Quality Brass-Cased Ammo: The Alamo 15 is precisely machined and runs best with consistent, quality ammunition. Federal, Hornady, Fiocchi, and Magtech are popular choices among users. Avoid steel-cased budget ammunition for regular use.
Set Your Pull Weight Before the Range: If your Alamo 15 has an adjustable pull weight, decide on your preferred setting before heading to the range and test it before serious use. Changing the setting mid-session can affect consistency.
Build Up to Speed Gradually: The first time you shoot the Alamo 15, resist the urge to immediately go full speed. Spend the first magazine or two learning where the reset is and how the break feels. Once you understand the trigger’s mechanics by feel, speed will follow naturally.
Keep the Roller Clean: The Graves Roller is the heart of the Alamo 15’s performance. After every 300–500 rounds, inspect the roller contact surface for carbon buildup and clean it. A properly maintained roller keeps the reset crisp and consistent.
Match Your Buffer to Your Build: H-2 for standard 16″ carbine builds. H-3 for SBRs, short-barreled pistol builds, or suppressed configurations. A flat wire spring paired with H-2 or H-3 is highly recommended by experienced Alamo 15 users for the smoothest cycling.
Practice Trigger Discipline at Speed: The fast reset of the Alamo 15 can make it easy to send rounds downrange faster than your sight picture is ready for. Practice deliberate, aimed shots at speed before doing full mag dumps. Accuracy should never be sacrificed for rate of fire.
Where to Buy the Alamo 15 Trigger
Finding a legitimate, reliable place to buy the Alamo 15 Trigger is important. The popularity of FRT triggers has attracted some questionable sellers alongside the legitimate ones. Here is how to buy safely.
Buy From Established Retailers With a Real Presence
Look for sellers with a verifiable business history, clear contact information, customer service channels, and transparent shipping and return policies. Major firearms e-commerce platforms carry the Alamo 15 — OpticsPlanet is one example where the trigger has been listed and reviewed.
Confirm State Compliance Before Ordering
Reputable retailers verify your shipping address against state restrictions before completing your order. This protects you. If a seller does not mention state compliance at all, that is a concern.
Avoid Cryptocurrency-Only Sellers Claiming to “Avoid Records”
This is the same red flag mentioned in our previous guides. Selling firearm accessories legally does not require cryptocurrency payments to hide records. Any seller promoting this angle is misleading you at best and potentially operating outside the law at worst. Legitimate Alamo 15 purchases go through standard payment channels with normal transaction records, just like buying any other legal product.
Check for Authorized Dealer Status
Where possible, look for retailers explicitly listed as authorized dealers for the Powered by Graves brand. This ensures product authenticity and that you will receive genuine manufacturer warranty coverage.
Expect to Pay $200–$300
The Alamo 15 Trigger is priced in the $200–$300 range from legitimate retailers. If you find a listing significantly below this range, approach with caution — counterfeits and inferior imitations exist in the FRT market. Pricing that seems too good to be true often is.
Factor in the Buffer Upgrade
If your rifle does not already have an H-2 or H-3 buffer, budget for one. A quality H-2 or H-3 buffer typically costs $20–$40 and is essential for reliable Alamo 15 operation. Buy the buffer at the same time as the trigger so your setup is complete from day one.
