Rare Breed FRT-SG3

The FRT-SG3 is Rare Breed's forced reset trigger for the B&T SPC9, GHM9, and GHM45, and it is the unit B&T USA now installs at the factory in SPC9 and GHM9 models under the partnership the two companies announced in July 2026. It is a drop-in pack: a custom housing sits in the B&T lower with no gunsmithing, fitting, or machining, and the kit ships with a 3-position ambidextrous B&T-style safety selector plus B&T-style hammer and trigger axle pins, so nothing else needs sourcing for the install.

The selector gives Safe, Semi, and FRT. Semi mode runs a two-stage pull at 4 to 4.5 lbs; FRT mode is a single stage at 5 to 5.5 lbs. In forced reset, the bolt carrier's rearward travel cams the trigger back into reset and locks it until the action returns to battery, so each round still takes its own press. Rare Breed builds the housing from 7075 anodized aluminum with heat-treated S7 steel internals, the same materials recipe as the FRT-MR3, and the assembled unit weighs 5 oz.

Fitment is specific: SPC9, GHM9, and GHM45 lowers only, and the B&T APC family is explicitly excluded. It also drops into the Lingle Industries aftermarket lower, though that install needs an AR-15 style 3-position selector and pins that are not in the box, and buyers running a B&T aluminum lower must note it on the order. Rare Breed sells direct at $525, capped at one trigger per transaction and one per customer per 24 hours, and does not ship to CA, CT, DE, HI, IL, MA, MD, NJ, NY, OR, RI, WA, or DC.
