Forged Aluminum Construction and Precision

The DPMS DA-15 lower receiver is forged from 7075-T6 aluminum and finished with MIL-A-8625 Type III hardcoat anodize, which meets military specifications for durability and corrosion resistance. Forged construction creates a stronger, more reliable receiver compared to billet alternatives. The multi-caliber marking on the lower means it can be used with standard AR-15 upper assemblies across multiple caliber configurations. All components use standard mil-spec AR-15 pattern interfaces, ensuring broad compatibility with aftermarket uppers and accessories.

Match Grade Lower Parts Kit and Trigger Performance

The included Davidson Defense Match Grade lower parts kit contains 31 precision components assembled to tighter tolerances than standard mil-spec kits. The single-stage straight trigger shoe delivers a clean 3.5-pound break with minimal creep, making it suitable for accurate shooting without the cost of premium triggers. Steel construction and black oxide finish provide durability, and the skeletonized design reduces weight. This is a functional, reliable trigger setup that works well for general-purpose shooting.

SBA3 Adjustable Brace and Buffer System

The SB Tactical SBA3 brace is one of the most popular stabilizing braces available. It features six adjustment positions on the mil-spec carbine buffer tube, allowing you to dial in comfort and control. The integrated stabilizing strap wraps around your arm to reduce felt recoil and improve handling. Flat Dark Earth finish matches modern tactical aesthetics. The brace is compatible with standard mil-spec sling mounts for QD attachment. The included Mil-Spec heavy-duty carbine buffer tube, 3-ounce buffer, and recoil spring complete the system and ensure reliable cycling.
