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 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

Behind the brace sits a Mil-Spec heavy-duty six-position carbine buffer tube, holding an 8-ounce buffer built in an extended, long profile and machined from stainless steel, finished in black. This extended buffer is designed for pistol-caliber blowback operating systems, giving 9mm, .45 ACP, and 10mm AR-pattern builds the added mass needed to properly time the blowback cycle, with the stainless steel construction offering corrosion resistance for long-term reliability. A standard AR-15 carbine recoil spring, made in the USA, completes the buffer assembly.

Buffer System Hardware

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.
