DPMS DA-15 Lower Receiver

The DPMS DA-15 is a forged aluminum lower receiver manufactured to mil-spec tolerances. The 7075-T6 aluminum alloy provides strength while keeping weight minimal. Black hardcoat anodizing per MIL-A-8625 Type III Class 2 protects against corrosion and wear. The multi-caliber marking means this receiver works with standard .223 Remington, 5.56 NATO, and other AR-15 caliber upper assemblies. The receiver features standard mil-spec magazine well and buffer tube interface compatibility, so any standard AR-15 upper will fit.

Davidson Defense Match Grade Lower Parts Kit

This 31-piece lower parts kit is the internal foundation of your lower assembly. The kit includes the fire control group, hammer, disconnector, trigger, selector, magazine catch, bolt catch, and all required springs and pins. The skeletonized straight trigger shoe reduces weight and provides a clean break at 3.5 pounds. Steel construction with black oxide finish ensures durability. Match Grade quality means tighter tolerances and smoother operation compared to standard mil-spec kits.

Magpul MOE RL Carbine Stock

The Magpul MOE RL is an adjustable polymer stock that attaches to the mil-spec carbine buffer tube. Six adjustment positions let you customize length of pull for different body types and shooting positions. Matte black polymer construction is lightweight and weather resistant. The stock features a QD sling attachment point and storage compartment. MOE RL stands for Magpul Original Equipment Rear Locking, meaning it locks securely to the buffer tube without wobble.

Complete Lower Assembly System

This kit provides all components needed to assemble a functioning lower receiver. The mil-spec 6-position carbine buffer tube accepts the included standard carbine buffer and recoil spring. The receiver end plate and castle nut secure the buffer tube to the lower receiver. Once assembled, this lower receiver accepts any standard AR-15 upper assembly. The combination creates a complete AR-15 rifle platform.
