SB Tactical SBA4X-04-SB SBA4 OD Green 5-Position Adjustable Brace for AR-Platform

The SB Tactical SBA4 OD Green is a mil-spec compatible stabilizing brace designed for AR-platform shooters who want a reliable, adjustable cheek rest and support interface. Built to work with any standard carbine receiver extension, the SBA4 gives you the flexibility to tune fit and control across five different length positions—whether you're running a compact build, going prone at distance, or adapting to body armor. The OD Green finish is durable and subdued, fitting naturally into modern tactical and hunting setups.

What sets the SBA4 apart is its thoughtful integration of practical features. The brace includes an integral ambidextrous QD sling socket, so you can mount a sling without modifying anything else. That means faster transitions and the ability to go hands-free when needed. The adjustable nylon strap keeps things secure during deployment, storage, or transport. The whole package reflects design input from U.S. veterans and is manufactured domestically, so you're getting engineering born from real-world experience and made in the USA.

The five-position adjustment range makes the SBA4 adaptable to different shooting positions, gear setups, and user preferences. You're not locked into a one-size-fits-most compromise; you dial in what works for your rifle and your shooting style. Whether you're building a duty-inspired carbine, a precision rifle with a tuned ergonomic profile, or a compact truck gun, the SBA4 gives you the control to get it right.
