It's built to standard AR-15 pattern magazine, fire control, buffer system, and grip compatibility.

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 curved mil-spec trigger, mil-spec hammer, disconnector, and mil-spec safety selector, along with the trigger guard, magazine catch assembly and release button, bolt catch assembly, pivot pin, takedown pin, buffer retainer, and the full set of detents and springs. 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 with its grip screw and washer.

Buffer System

The buffer tube is a Davidson Defense heavy-duty, 6-position mil-spec diameter carbine receiver extension 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 recoil buffer built with a 6061 aluminum body, steel internal weights, and a polymer impact pad, along with a USA-made standard AR-15 carbine recoil spring. A Davidson Defense mil-spec castle nut in black and a US Tactical mil-spec receiver end plate complete the receiver extension hardware.

It features an extended, molded upper cheek-weld surface and a textured molded butt surface, with length-of-pull adjustment across multiple positions via a spring-loaded adjustment lever.
