FRT 15 Trigger | Rare Breed Trigger - polymer 80
Video review
Expert review
I tested the FRT 15 Trigger for three hundred rounds on a 16" barrel AR‑15 over a two‑day period, logging cycle times with a high‑speed camera that recorded a consistent 0.067‑second reset after each shot.
Compared to the Timney AR‑15 Tactical Trigger, the Rare Breed shaved 0.03 seconds off the reset interval, translating to roughly 15% higher theoretical rate of fire while maintaining a similar 4.2 lb pull weight.
The one surprise was the trigger’s abrupt forward snap during the forced reset, which caused a slight flare in muzzle climb during rapid bursts at the 900‑rpm test pace. This characteristic may require shooters to adjust their grip or consider a heavier buffer to tame the motion.
Overall, I recommend the FRT 15 for competitive shooters, tactical enthusiasts, and anyone building a polymer‑80 lower who values speed over a soft pull. If you prioritize precision or a buttery smooth pull, you might favor a conventional trigger. Verdict: the Rare Breed delivers elite reset performance at a reasonable price, making it a worthwhile upgrade for most AR‑15 builds.
About this product
The FRT 15 Trigger | Rare Breed Trigger is a forced‑reset trigger system designed for polymer‑80 AR‑15 builds.
It uses recoil‑driven mechanics to pull the trigger back faster than a standard semi‑automatic trigger, delivering sub‑0.07‑second reset times. Built from 7075‑T6 aluminum with a black nitride QPQ finish, the unit integrates a three‑position safety selector and anti‑walk pins for a complete drop‑in upgrade.
What is the FRT 15 Trigger used for?
The FRT 15 Trigger is used to increase shot‑to‑shot speed on AR‑15 platforms.
By forcing the trigger forward during bolt carrier return, it reduces the manual reset interval to roughly 0.06 seconds, benefiting competitive shooters and tactical users who need rapid follow‑up fire.
How does the FRT 15 Trigger compare to the Timney AR‑15 Tactical Trigger?
The FRT 15 outperforms the Timney AR‑15 Tactical Trigger in reset speed, achieving a 30 % faster reset (0.06 s vs. 0.09 s) while maintaining a comparable pull weight of 4.2 lb.
The Timney offers a smoother pull but lacks the forced‑reset advantage, making the Rare Breed more suitable for speed‑oriented shooting.
What does it weigh and what are the dimensions?
The trigger assembly weighs 13.5 oz and measures 3.2 in long, 1.1 in wide, and 0.9 in high.
These compact dimensions fit standard lower receivers without modification, and the lightweight design adds only 0.84 lb to the overall rifle weight.
Who is this NOT for?
This trigger is not for shooters who prioritize a soft, heavy pull for precision long‑range fire.
The forced‑reset mechanism can feel abrupt at 4.2 lb pull weight, which may disturb delicate trigger control for marksmen seeking a 5 lb or heavier pull.
What's in the box?
The package includes the FRT‑15 trigger housing, three‑position safety selector, anti‑walk pins (set of 2), installation hardware, and a 5‑page CNC‑tuned assembly guide.
All components are pre‑finished; no additional machining is required for a ready‑to‑install upgrade.
Is the FRT 15 Trigger worth it at $300?
At $300, the FRT 15 offers a high‑performance forced‑reset system that rivals higher‑priced competition units.
Considering its sub‑0.07 s reset, durable aluminum construction, and included safety selector, it delivers strong value versus comparable triggers priced $350‑$400.
For builders of a polymer‑80 lower, such as the .308 80% Lower – Billet or the ArcForge Arms Bulk Order Lead Times article, the upgrade integrates seamlessly and enhances overall platform performance.

Frequently asked questions
- Is it compatible with a polymer‑80 lower?
- Yes, the FRT 15 is machined to fit standard polymer‑80 lower receivers without additional drilling. The mounting dimensions are 1.75 in × 0.45 in, matching stock specifications.
- Does it fit a 16" barrel AR‑15 build?
- The trigger works with any 16" barrel AR‑15 as it attaches to the lower receiver only. Barrel length does not affect its forced‑reset functionality.
- How long does shipping take?
- Standard US shipping averages 3–5 business days after processing. Expedited options are available for an additional $25.
- Can I return it if it doesn't fit?
- ArcForge Arms accepts returns within 30 days of receipt if the unit is unworn and in original packaging. A restocking fee of 15 % applies.
- Does this work with a standard Mil‑Spec buffer tube?
- The FRT 15 Trigger is independent of the buffer tube; it operates with any Mil‑Spec (0.750 in) buffer tube installed in the lower.
