Rare Breed Triggers’ FRT-15s FOR SALE | AVAILABLE IN STOCK

About this product

This Rare Breed FRT-15 listing is a drop-in, forced-reset AR-15 trigger built with a 7075-T6 aluminum housing and precision wire EDM-cut internal components — the trigger, hammer, and locking bar. Like the standard FRT-15 design, it fires exactly one round per trigger pull; the forced-reset mechanism only affects how the trigger resets as the bolt cycles, not how many rounds fire per pull. Despite marketing that says it ships nationwide, forced-reset triggers are restricted in California, and we cannot ship this product to a California address.

What is it used for?

It's a trigger upgrade for AR-15 owners chasing a lighter, more consistent pull — this version is built around a 5 lb trigger pull weight — combined with the forced-reset function that resets the trigger as the bolt carrier cycles rearward. Each pull still fires one round, same as a factory trigger; nothing about the design changes the rifle's semi-automatic function. It's marketed toward 5.56 NATO and .300 Blackout AR-15 builds, both of which share the same mil-spec lower receiver dimensions.

What's different about this construction versus a steel FRT-15?

This unit uses a 7075-T6 aerospace-grade aluminum housing rather than an all-steel housing, with the trigger, hammer, and locking bar wire EDM-cut for tight tolerances, and a Black Nitride QPQ finish with anti-walk pins to keep the pins from migrating out under recoil. The listed 5 lb trigger pull is on the lighter end for an AR-15 trigger, which the manufacturer markets as helping with faster, more consistent follow-up shots. As with any forced-reset trigger, the mechanical function — one round per pull, reset assisted by bolt travel — is what defines the category, not the housing material.

What does it require to function correctly?

It requires a full-auto-profile bolt carrier group for the locking bar mechanism to engage correctly — a standard AR-15 semi-auto carrier will not work with it. The manufacturer recommends a heavier buffer (H2, H3, or T3) than the standard carbine buffer most AR-15s ship with, to manage the different cycling dynamics. Professional installation is advised rather than a simple owner drop-in for this particular listing, so budget for gunsmith time if you're not experienced with AR-15 fire-control-group work.

Does it work in California?

No. Regardless of the generic marketing claim that it ships nationwide, forced-reset triggers are restricted in California, and current state law and ongoing federal litigation around the FRT design mean we cannot ship this product to a California address. See our California gun laws page for related AR-15 component restrictions, and confirm current law in your own state before ordering if you live elsewhere.

How does it compare to the standard FRT-15?

The core mechanical function is identical to Rare Breed's original FRT-15 — one round per pull, reset assisted as the bolt cycles — but this listing's aluminum housing, EDM-cut internals, and stated 5 lb pull weight are specific selling points of this particular build. If you're choosing between listings, the differences are in construction and finish, not in what the trigger legally does.

Who is this trigger not for?

It's not for anyone in California or another state where forced-reset triggers are restricted, regardless of what generic marketing copy claims about shipping — we verify state law before every shipment, not after. It's also not the right choice for a shooter who mainly wants a lighter trigger pull without the added bolt carrier and buffer requirements; a standard drop-in single-stage AR-15 trigger is a simpler upgrade for that goal. And it's not a fit for anyone building on an AR-10 or LR-308-pattern lower, since the fire-control-group dimensions don't match.
