Lower Receiver

The DPMS DA-15 lower receiver is forged from 7075-T6 aluminum and finished in black hardcoat anodizing per MIL-A-8625 Type III Class 2, giving it a durable, wear-resistant surface. It carries a Multi-Cal caliber marking along with standard SAFE/FIRE selector markings, and it's built to a standard AR-15 pattern magazine well and buffer extension interface, keeping it compatible with standard mil-spec AR-15 components.

Lower Parts Kit

The included Davidson Defense Lower Parts Kit is a complete, 31-piece mil-spec set covering the full fire control group, including a standard mil-spec trigger with a curved trigger shoe and the trigger guard, along with the smaller pins, springs, and detents a lower needs to function. Its components are built from a mix of steel, aluminum, and polymer, finished in Phosphate and anodized coatings. A mil-spec A2 pistol grip in black is included as well.

Buffer System

The buffer tube is a Davidson Defense heavy-duty, 6-position unit machined from 6061 aluminum and finished in Type II anodizing, measuring 7.15 inches long with a 1.145-inch outer diameter, a 1-inch inner diameter, and a weight of 3.8 ounces. It's paired with a 3-ounce standard AR-15 carbine buffer and a standard AR-15 carbine recoil spring, along with a US Tactical mil-spec receiver end plate and an AR-15 carbine castle nut to secure it to the lower receiver.

Brace

The SB Tactical SBA3 is an adjustable pistol stabilizing brace finished in Stealth Gray, built from impact-resistant polymer in a streamlined, carbine-style profile. It includes an adjustable nylon stabilizing strap and mounts to a mil-spec carbine receiver extension or buffer tube, such as the one included in this kit, via a slide-on adjustable carbine-style mount.
