Compact Pistol Configuration

This 10.5-inch platform delivers a short overall length ideal for confined spaces and vehicle storage. The carbine-length gas system paired with the compact barrel length creates a balanced recoil impulse without excessive noise or blast. The KeyMod handguard supports tactical accessories, and the low-profile gas block keeps the upper profile clean for optic mounting.

Complete Component Inclusion

The kit arrives with all upper and lower components needed to complete a functional rifle. The bolt carrier group is finished in Nitride for durability, the charging handle is mil-spec quality, and the buffer system uses standard carbine specifications. The lower parts kit handles trigger control, hammer function, and magazine operation. Lower receiver not included.

Drop-In Trigger Ready Design

The standard trigger group functions reliably for most shooters, but the kit's design supports drop-in trigger upgrades without modification. If you want to customize the trigger pull or reset speed later, the receiver dimensions accommodate aftermarket options without fitting or alteration.

Brace and Legal Configuration

The polymer stabilizing brace provides control and stability during shooting. This configuration maintains pistol legal status when used as designed. Always verify current federal and state laws regarding pistol braces and configurations before assembly or use.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. BCG and charging handle are not included in upper build kits, but this is a full build kit and includes both.
