This kit pairs an SB Tactical SBA6 pistol stabilizing brace with a complete Mil-Spec heavy-duty six-position carbine buffer tube system fitted with LR-308/AR-10 buffer hardware, giving the buyer everything needed to complete the rear end of an AR-10 pistol build in one package.
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.
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.
Follow all manufacturer instructions and safe handling practices.
Ensure compliance with all applicable federal, state, and local laws.
