Premium Match Grade Components

This kit stands out because of the Davidson Defense Match Grade lower parts kit included. The 31-piece set ensures smooth trigger operation and reliable fire control. The 3.5 lb trigger pull is significantly lighter than mil-spec triggers, making it easier to manage during rapid fire sequences. The skeletonized trigger design reduces weight while maintaining structural integrity.

Heavy Duty Pistol Buffer System

The buffer system uses a heavy duty pistol buffer tube paired with a standard carbine buffer and recoil spring. This combination is designed specifically for the reduced recoil impulse of pistol configurations. The fixed pistol receiver extension provides secure mounting for the Gauntlet Arms brace and ensures reliable cycling across various ammunition types.

Gauntlet Arms FDE Stabilizing Brace

The included Gauntlet Arms brace is a fixed polymer design in Flat Dark Earth finish. It features integrated sling attachment slots for accessory mounting and a lightweight skeletonized profile that keeps overall weight minimal. The brace mounts directly to the pistol buffer tube using standard AR-15 compatibility.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Upper receiver and bolt carrier group are not included. Lower receiver not included in this kit, as the DPMS DA-15 lower receiver is the serialized component included.
