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, with a height of roughly 4.5 to 5.0 inches and a width of up to 2.1 inches at its widest point. 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.

Lower Parts Kit

A .308 Mil-Spec quality Lower Parts Kit, built for the AR-10/LR-308 platform, covers the fire-control and lower-control internals needed to complete a stripped lower on this platform.

Buffer Tube and Buffer System

Behind the brace sits a Mil-Spec heavy-duty six-position carbine buffer tube, holding a Davidson Defense LR-308 collapsible stock buffer weighing 3.76 ounces and an AR-10 carbine extra-power buffer spring machined from 17-7 stainless steel and made in the USA. 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.
