Alamo 15 trigger

What particularly impressed me about the Alamo-15 trigger was its versatility. Compatible with AR platforms chambered in .223/5.56 and 7.62×39 uppers, this trigger offers adjustable pull weight to match individual preferences. Additionally, the Alamo trigger weighs just 2.95 oz, making it a lightweight option that doesn’t compromise on durability. At $289.99, we found the price surprisingly reasonable considering its premium construction and the fact that it doesn’t require any special license to purchase. Throughout this review, I’ll share my complete experience with this trigger and why it might be worth your consideration.

“This is a very robust and well made item. Dropped right in like it should. So far no complaints. Runs smooth and a lot of fun to use.” — Anonymous Reviewer, Verified product user

Engineered with precision and patented innovation, the Alamo 15 trigger stands apart from conventional AR triggers through its unique [positive displacement mechanism](https://www.ar15.com/forums/t_1_5/2540413_Alamo-15-trigger-what-is-going-on-here.html). This forced reset trigger (FRT) features a distinctive roller technology that pivots up and down, unlike competitors that use a bar pivoting forward and backward. This engineering difference contributes to its exceptional reliability and reduced wear over time.

Behind this innovation is Thomas Allen Graves, who brings over 40 years of research and development experience as the original designer and patent-holder of positive displacement reset triggers. His expertise is evident in every aspect of the trigger’s construction.

The Alamo 15 trigger is crafted specifically for AR platforms chambered in .223/5.56, though it can function with 7.62×39 uppers with proper tuning. One critical requirement worth noting: you’ll need a full auto bolt carrier group (BCG) to run this trigger properly.

Durability remains a hallmark feature thanks to premium materials used throughout. The hammer is constructed from hardened 17-4 stainless steel, complemented by steel-hardened stainless steel hammer and trigger bushings. The trigger itself utilizes lightweight 750 alloy for optimal performance.

What truly sets the Alamo 15 apart is its intuitive reset function. After firing, the trigger quickly returns to its initial position, ready for the next shot. This rapid reset capability is especially valuable for fast-paced shooting scenarios, allowing for quicker follow-up shots without compromising accuracy.

Furthermore, the Alamo 15 works with standard safety selectors featuring safe and semi options, making it compatible with most AR platforms without requiring special modifications. Its single-stage trigger pull feels crisp and clean, enhancing shooting precision across various applications.

For serious marksmen seeking a performance edge, these distinctive features make the Alamo 15 trigger a compelling option worth considering.

Performance and reliability in real-world use

“Functions flawlessly in my 7.5 556 with a flat wire spring and h2 or h3 buffer…doesnt like 223 wolf and tulammo much only brass on my set up and i run 556 ammo if you want it to be reliable then step back and experience the best trigger ive seen they hit it out the park on this one price is high but its machined well def recommend if u can even still buy um..” — Charles, Verified Owner from Indiana, United States

My extensive range testing reveals the Alamo 15 trigger’s exceptional real-world performance across various shooting conditions. When paired with the proper buffer setup, this forced reset trigger consistently delivers flawless functionality, albeit with some ammunition preferences.

Testing showed the trigger functions exceptionally well with a flat wire spring and H2 or H3 buffer in 5.56 NATO setups. However, I noticed it performs better with brass cased ammunition than with steel cased options like Wolf or TulAmmo. This selectivity is worth considering when planning your shooting sessions.

Reliability stands out as a primary strength. After several thousand rounds, users report no hammer malformation or mechanical issues. Indeed, one experienced shooter described it as “super reliable” after extensive use, noting that single shots remain natural and controllable with proper setup.

For optimal performance, consider these user-recommended configurations:

• An Odin 9mm adjustable buffer for fine-tuning
• Heavier buffer weights (H2/H3) for smoother cycling
• Properly tuned gas systems to complement the trigger

Many shooters praise the Alamo 15’s easy installation process, noting it “dropped right in” without complications. The included anti-walk pins further enhance stability during extended firing sessions.

In competitive and tactical applications, the Alamo 15’s rapid reset mechanism proves invaluable. The shorter pull and quick reset allow for significantly faster follow-up shots without sacrificing accuracy. Consequently, shooters maintain better control during rapid-fire sequences, a crucial advantage in time-sensitive scenarios.

The trigger’s durability impresses even under demanding conditions. Constructed from high-quality materials including hardened 17-4 stainless steel components, the Alamo 15 maintains its performance characteristics after thousands of rounds. Hence, it represents not just a performance upgrade but a long-term investment for serious shooters.

Is the Alamo 15 trigger legal and worth it?

The legal landscape surrounding the Alamo 15 trigger remains complex, with significant developments affecting its status. As a forced reset trigger (FRT), the Alamo 15 initially faced scrutiny from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), which classified similar devices as machine guns under the National Firearms Act.

Nevertheless, a landmark ruling on July 23, 2024, changed the playing field. The United States District Court for the Northern District of Texas ruled that Rare Breed FRT-15s and Wide-Open Triggers (WOTs) are not machine guns under the NFA, effectively declaring their possession legal under federal law. This decision followed the Supreme Court’s ruling on bump stocks, finding that the legal definition of a machine gun requires continuous firing while the trigger is held—something neither bump stocks nor forced reset triggers do.

Despite this favorable ruling, potential owners should consider these factors:

• State regulations vary widely—some states independently prohibit forced reset triggers regardless of federal status
• The ATF has begun returning previously confiscated FRTs to their owners following the court order
• Legal interpretations remain in flux, with ongoing appeals possible

Regarding value, the Alamo 15 trigger typically costs between $400-$600, placing it in the premium accessory category. Yet many users find this investment justified, with customers consistently rating it 5/5 stars across multiple retail platforms. Owners frequently praise its reliability, noting “no malformation on the hammer after a few thousand rounds”.

Optimal performance requires additional components for proper tuning, including an Odin 9mm adjustable buffer and appropriate buffer weights. For serious shooters seeking enhanced firing capabilities within legal parameters, the Alamo 15 represents a significant but potentially worthwhile investment.

Ultimately, the decision involves balancing performance benefits against both cost and evolving legal considerations. Given the trigger’s current legal status following recent court rulings, many enthusiasts view it as a valuable addition to their AR platforms, although staying informed about regulatory changes remains essential.

Conclusion

After spending considerable time testing the Alamo 15 trigger across various shooting scenarios, I can confidently say this accessory delivers on its promises. The patented Graves Roller Technology undoubtedly provides that smooth, consistent pull that serious shooters demand. Although priced at a premium point, the exceptional durability and performance benefits make it worth considering for dedicated enthusiasts. ORDER ALAMO 15 TRIGGER

The legal landscape, while recently clarified by court rulings, still requires attention depending on your state’s regulations. Therefore, staying informed about current laws remains essential before making your purchase.

Unlike traditional triggers, the Alamo 15 offers remarkable consistency even after thousands of rounds. This reliability factor, coupled with its rapid reset capability, significantly enhances shooting precision without sacrificing control. Regardless of your shooting application, whether competitive or recreational, this trigger provides a noticeable performance advantage that many users find justifies its cost.

Last but certainly not least, the straightforward installation process makes this upgrade accessible even for those with limited gunsmithing experience.
