Match Grade Lower Parts Kit

This kit includes a Davidson Defense Match Grade 31-piece lower parts kit in Generation 2. The match grade designation means the components are precision-fitted and finished to tighter tolerances than standard mil-spec parts. The straight trigger shoe provides a clean break at 3.5 pounds with a skeletonized steel construction finished in black oxide. All fire control components, selector markings for SAFE and FIRE, and the A2-style mil-spec grip are included.

Advanced Recoil Management

The included mil-spec enhanced stock features an advanced recoil dampener suspension system paired with a screwed rubberized recoil pad. This combination reduces felt recoil impulse and helps manage muzzle rise during rapid fire. The adjustable polymer cheek riser allows you to dial in the perfect sight picture height without adding bulk or weight to the platform.

Mil-Spec Carbine Buffer System

The buffer system uses a mil-spec heavy-duty carbine buffer tube with 6-position adjustability. A standard 3-ounce carbine buffer pairs with a standard carbine recoil spring. The US Tactical mil-spec receiver end plate and AR-15 carbine castle nut complete the assembly. This configuration cycles reliably across standard AR-15 ammunition and upper combinations.

DPMS DA-15 Lower Receiver

The lower receiver is a forged unit manufactured from 7075-T6 aluminum, a material choice that balances strength and weight. The black hardcoat anodized finish meets MIL-A-8625 Type III Class 2 specifications for durability. The receiver is marked for multi-caliber compatibility and uses standard AR-15 pattern magazine well and buffer extension interfaces. The DPMS DA-15 is a serialized component and the registered firearm.
