The DPMS DA-15 is a stripped lower receiver built from 7075-T6 forged aluminum with Type III hard coat anodizing. This is the foundation component for any AR-15 build, designed to accept standard mil-spec lower parts kits and work across multiple calibers on the AR-15 platform.
The 7075-T6 aluminum alloy is one of the strongest aluminum options available for firearm receivers. Forged construction means the material is compressed and shaped under pressure, creating a denser structure than cast alternatives. The Type III hard coat anodizing per MIL-A-8625 specification provides a protective oxide layer that resists scratches, corrosion, and environmental wear while maintaining the black finish.
This stripped lower receiver accepts any standard mil-spec AR-15 lower parts kit, making it compatible with the broadest range of aftermarket components. The magazine well follows standard AR-15 dimensions, and the buffer extension interface is mil-spec, meaning you can use standard buffer tubes, springs, and stocks or braces depending on your build configuration. The multi-caliber marking indicates the receiver is not restricted to a single caliber, allowing you to build multiple upper configurations on the same lower.
A stripped lower receiver is the only part of an AR-15 that is legally classified as a firearm and requires serialization. Everything else—upper receiver, barrel, handguard, bolt carrier group—can be purchased and shipped without restrictions. This lower receiver arrives completely stripped, meaning you'll need to install a lower parts kit to make it functional. The DPMS DA-15 uses standard mil-spec dimensions throughout, so compatibility with aftermarket parts is straightforward and well documented across the AR-15 community.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. This is a serialized firearm component and must be registered or transferred according to your jurisdiction's requirements.
