DPMS DA-15 Lower Receiver Quality

The forged 7075-T6 aluminum construction delivers durability and precision machining. The multi-caliber marking indicates compatibility with standard AR-15 upper assemblies across various calibers. Hard anodized finish per military specification provides corrosion resistance and wear protection. Mil-spec buffer tube interface and magazine well ensure compatibility with standard AR-15 components.

Davidson Defense Match Grade Lower Parts Kit

This 31-piece kit includes all internal lower receiver components needed for assembly. The match-grade designation reflects precision tolerances in the trigger group, hammer, disconnector, and selector components. The skeletonized straight trigger shoe reduces weight while maintaining the 3.5-pound pull weight specification. All components are finished in black oxide for corrosion resistance.

SB Tactical SBA5 Stabilizing Brace Configuration

The SBA5 provides an adjustable carbine-style profile designed for pistol stabilization. The brace mounts directly to the mil-spec carbine buffer tube included in this kit. Integrated QD sling attachment point allows for optional sling mounting. The collapsible design with six adjustment positions accommodates different grip preferences and shooting styles.

Buffer System and Receiver Extensions

The kit includes a mil-spec heavy-duty 6-position carbine buffer tube, standard 3 oz carbine buffer, and standard carbine recoil spring. The US Tactical receiver end plate and AR-15 carbine castle nut complete the buffer tube assembly. These components are standard mil-spec specifications compatible with the included brace and any standard AR-15 upper assembly.
