Pistol Lower Build Kit Overview

This kit gives you everything required to assemble a functional lower receiver for an AR-15 pistol. The DPMS DA-15 lower is forged from 7075-T6 aluminum and finished with MIL-A-8625 Type III Class 2 black hardcoat anodize, meeting military specification standards. The receiver is marked for multi-caliber use, so it pairs with upper assemblies in 5.56, 9mm, .300 BLK, and other AR-15 compatible calibers. The serialized lower receiver is the regulated component that defines the firearm legally.

Davidson Defense Match Grade Lower Parts Kit

The included lower parts kit is a complete 31-piece assembly from Davidson Defense graded as Match Grade quality. This means tighter tolerances and better fit compared to standard mil-spec parts. The trigger is a single stage straight trigger shoe design with a 3.5 lb pull weight, skeletonized steel construction with black oxide finish. The fire control group, hammer, disconnector, and all pins and springs needed to complete the lower are included. The Mil-Spec A2 grip is installed and ready to use.

KAK Blade Pistol Stabilizer Brace

The KAK Industry Blade is a fixed blade-style pistol arm stabilizer brace made from glass filled polymer in black. It mounts directly to the heavy duty pistol buffer tube included with this kit. The brace features a sling loop mount for attaching a single point or two point sling. The fixed design provides a solid, stable platform for one-handed or two-handed shooting while keeping the overall length in the pistol category. The brace is configured specifically for pistol buffer tube compatibility.

Buffer System for Pistol Configuration

The kit includes a heavy duty pistol buffer tube paired with a standard AR-15 carbine buffer weighing 3 oz. and a standard carbine recoil spring. This combination cycles the action reliably in a compact package. The receiver end plate is US Tactical mil-spec, and the castle nut secures the buffer tube assembly. All components are manufactured to standard AR-15 specifications for compatibility with quality uppers.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Upper receiver not included. Lower receiver is the serialized component that defines the firearm legally.
