Cmc Ar-15 Lpk Without Grip/fcg

The CMC AR-15 Lower Receiver Parts Kit Without Grip/FCG is a purpose-built component set designed for AR-15 builds where the fire control group and pistol grip are sourced separately. Manufactured by CMC Triggers, this lower parts kit delivers verified, quality parts that handle the mechanical foundation of the platform, making it an essential choice for builders who need flexibility in trigger and grip selection or who are integrating premium aftermarket components into custom builds.

This kit includes 13 verified components: bolt catch assembly (catch, plunger, spring, and roll pin), magazine release assembly (button and spring), buffer retainer spring, safety selector with detent spring and detent pin, and trigger guard. Each part is manufactured to specification for reliable function in the lower receiver. The exclusion of the fire control group and grip means builders retain control over trigger performance characteristics and ergonomic grip choice—critical for competitive shooters, duty-rated builds, or operators with specific trigger requirements. Weight of 0.19 lbs reflects a pure component set with minimal packaging material.

This parts kit serves AR-15 builders ranging from first-time assemblers to experienced gunsmiths. It is ideal for those constructing a custom lower receiver from a raw 80% or stripped receiver, rebuilding a platform with upgraded triggers, or assembling a modular configuration where trigger group sourcing is handled independently. The kit accelerates lower assembly while leaving the trigger and grip as open selections, enabling shooters to match components to their intended mission profile, whether patrol duty, precision rifle work, or competition.

For builders investing in quality AR-15 builds, a lower parts kit without fixed trigger or grip components offers flexibility at a critical assembly stage. CMC Triggers manufactures components trusted across the platform, and this kit enables the selection of precision triggers—single-stage match triggers, two-stage setups, or specialty fire control groups—alongside ergonomic grips matched to hand size and shooting role. This modular approach is standard among serious builders.
