Enhanced Stock Comfort

The adjustable polymer cheek riser on this stock provides a better sight line when using optics or iron sights mounted on the upper receiver. The rubberized recoil pad absorbs impact and reduces felt recoil, making extended shooting sessions more comfortable. Length of pull adjustment ensures the stock fits properly regardless of your body size or gear setup.

Forged 7075-T6 Aluminum Construction

The DPMS DA-15 lower receiver uses forged 7075-T6 aluminum, which offers superior strength compared to standard 6061 aluminum. The black hardcoat anodized finish meets MIL-A-8625 Type III Class 2 specifications, providing corrosion resistance and durability. The multi-caliber marking on the lower means it works with any AR-15 caliber upper you choose to pair with it.

Complete Lower Parts Kit Included

The Davidson Defense 31-piece lower parts kit includes all internal components needed to function: trigger, hammer, disconnector, selector, magazine catch, bolt catch, and all required pins and springs. Everything arrives phosphate and anodized finished, ready for assembly. No additional parts are required to complete the lower receiver.

Standard Mil-Spec Compatibility

This lower receiver accepts any standard mil-spec AR-15 upper assembly. The magazine well, buffer extension interface, and all mounting points follow mil-spec dimensions. The 6-position buffer tube and mil-spec carbine-length buffer system provide reliable cycling with standard AR-15 ammunition and uppers.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
