The bundle includes a Davidson Defense heavy-duty, 6-position mil-spec carbine receiver extension machined from 6061 aluminum in black, matching the brace's mounting interface. It's paired with an 8-ounce stainless steel extended pistol-caliber buffer in black, built for pistol-caliber blowback operating systems across 9mm, .45 ACP, and 10mm, along with a USA-made standard AR-15 carbine recoil spring. A Davidson Defense mil-spec castle nut and a US Tactical mil-spec receiver end plate complete the receiver extension hardware.
