Quality Lower Receiver Foundation

The DPMS DA-15 lower receiver is forged from 7075-T6 aluminum and finished with mil-spec hardcoat anodization. This construction method provides durability and dimensional consistency. The multi-caliber marking allows flexibility for different upper assemblies. The receiver is serialized and requires transfer through a licensed dealer.

Match Grade Trigger and Lower Parts

The included Davidson Defense Match Grade lower parts kit contains 31 precision components. The skeletonized straight trigger shoe breaks at 3.5 pounds and uses black oxide steel construction. This trigger design reduces weight and provides a clean break for controlled shooting. The complete lower parts kit handles all internal lower receiver functions.

SBA3 Adjustable Stabilizing Brace

The SB Tactical SBA3 is an adjustable carbine-style brace that mounts to the mil-spec buffer tube. The design allows length-of-pull adjustment across six positions. An integrated stabilizing strap and QD sling socket provide control and mounting options. The compact profile maintains the pistol configuration while supporting shooting comfort.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Verify that all components are compatible with your intended configuration before assembly.
