Rare Breed FRT-15L3 Performance

The FRT-15L3 is a forced reset trigger that eliminates manual trigger reset between shots. When the bolt cycles back after firing, the trigger automatically resets, allowing you to fire faster than traditional semi-automatic triggers. Each shot still requires a separate trigger pull, keeping it fully legal under federal law. The three-position safety selector works in both FRT and semi-auto modes, giving you flexibility in how you want to shoot.

Build-Ready Lower Assembly

This kit arrives with everything needed to complete the lower receiver except the upper assembly and bolt carrier group. The Davidson Defense receiver is precision-forged from 7075-T6 aluminum and hard anodized for durability. The KAK Industry lower parts kit handles trigger function, hammer, disconnector, selector, magazine catch, and bolt catch. The mil-spec heavy-duty buffer tube, recoil spring, end plate, and castle nut complete the rear assembly.

What You Should Know

The FRT-15L3 is currently legal under federal law as of December 2025, but always verify your state and local regulations before purchasing. The trigger operates in two modes: standard semi-automatic and FRT mode. This is a lower build kit only. You'll need an upper assembly with bolt carrier group and charging handle to complete a functional rifle. The no-logo receiver is ideal if you prefer unmarked aluminum.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Upper receiver, bolt carrier group, and charging handle are not included.
