Key Features

• SB Tactical SBA6 pistol stabilizing brace, 5-position adjustable
• Slim, lightweight, snag-resistant carbine-style profile

Stabilizing Brace

The SBA6 is molded from high-strength, impact-resistant polymer in a streamlined, carbine-style profile and finished in matte black. It adjusts across 5 positions, running from approximately 6.2 to 10.25 inches in length depending on the position selected, and weighs approximately 9 ounces, keeping the overall footprint slim and snag-resistant. The rear surface carries a slim, non-slip rubberized texture, and an adjustable nylon stabilizing strap is included for securing the brace to the forearm.

Buffer Tube and Buffer System

Behind the brace sits a Mil-Spec heavy-duty six-position carbine buffer tube, holding a Davidson Defense AR-15 9mm carbine buffer built for 9mm AR-style platforms and a standard USA-made recoil spring. A US Tactical AR-15/M16 Mil-Spec receiver end plate and AR-15 carbine castle nut secure the entire buffer tube assembly to the lower receiver.
