Rare Breed FRT 15 Trigger

Description

Standard, E3, or L2)

Precision-machined components with hardened contact surfaces

Patent-protected reset mechanism (US Patent #10,822,774)

Compatible with mil-spec AR-15 lower receivers

Requires M16-cut bolt carrier group for proper function

Build and finish

The FRT-15’s billet aluminum housing contains a proprietary cam system that forces the trigger forward after each shot. Unlike conventional triggers that rely solely on spring tension for reset, this mechanism positively drives the trigger forward at a consistent rate regardless of firing cadence.

Internal components use Carpenter 158 tool steel for high-wear areas, with phosphate-coated springs rated for 50,000+ cycles. The trigger shoe features a flat face design with 3.5-4.5 lb pull weight (varies by model) and crisp break. All variants use sealed bearings rather than sliding friction points to maintain performance in dirty conditions.

Compatible platforms

• AR-15 pattern rifles with mil-spec lower receivers
• Requires M16-cut bolt carrier group (not included)
• Not compatible with AR-10/SR-25 platforms
• Check local laws before installation – some jurisdictions restrict forced reset triggers

Installation notes

Installation requires basic armorer’s tools and proper staking of the safety selector detent. The trigger group drops in using standard pins, but function checks should verify hammer clearance with your specific BCG. Rare Breed provides detailed torque specs for the set screws that adjust reset timing.

For AR-15 owners seeking mechanical precision rather than electronic solutions, the FRT-15 delivers a unique operating system that maintains reliability while offering distinct performance characteristics. As with all firearm modifications, proper installation and testing are essential before live fire.
