SB Tactical SBA4 Black 5-Position Adjustable Brace

The SB Tactical SBA4 Black 5-Position Adjustable Brace is a stabilizing brace engineered for shooters who need a reliable, adjustable fit on their AR platform firearms. Built with the same proven design philosophy as its predecessor, the SBA4 gives you the flexibility to dial in the right length of pull for your body, shooting position, and gear setup. Whether you're running a short-barreled rifle for home defense, a pistol-configured build, or just prefer the control of an adjustable platform, this mil-spec compatible brace delivers everyday functionality backed by US manufacturing.

The SBA4's five-position design means you can tailor the fit without tools—a genuine advantage when you're troubleshooting stance, swapping between seated and standing positions, or running different levels of body armor. At 10 ounces, the brace adds minimal weight while the integral ambidextrous QD sling socket lets you attach your favorite sling system without aftermarket adapters. The one-inch nylon strap is adjustable, so you can secure the brace to your arm or shoulder however works best for your build.

This is a no-nonsense piece of equipment: it works with any mil-spec carbine extension tube, it comes in a tactical black finish, and it's made in the USA. If you're assembling a pistol-platform rifle or modernizing an existing short-gun, the SBA4 is a proven choice that lets you focus on shooting, not fiddling.
