SB Tactical SBA3X Adjustable 5-Position Black Synthetic Brace for AR-Platform

The SB Tactical SBA3X is a 5-position adjustable brace designed for AR-platform firearms built on mil-spec carbine receiver extensions. If you're running a modern tactical rifle, pistol-caliber carbine, or short-barreled rifle and want a stabilizing solution that adapts to your body type and shooting style, this brace delivers the adjustability and control that shooters demand without unnecessary bulk. The minimalist synthetic design keeps weight down while the integral, ambidextrous QD sling socket lets you mount support gear quickly—useful whether you're at the range, in a defensive scenario, or hunting in varied terrain.

Built in the USA and veteran-designed, the SBA3X reflects the practical ethos of shooters who've learned what works. The five-position adjustment scheme (spanning 6.75" to 9.5" in length) means you can dial in a fit that works with your arm length and gear configuration. The 1.0" nylon strap cinches down for a secure, repeatable hold, and the 1.8"-wide profile sits comfortably on the forearm without getting in the way of controls or mag changes. At just 6.75 oz, it won't noticeably load down your rifle.

Important: SB Tactical braces are engineered as forearm stabilizers to improve accuracy and control from a two-handed, supported position. They are not designed or intended for shoulder firing, and federal regulations treat them as such. Always verify your local and state laws before purchasing, as firearm classifications can vary by jurisdiction and configuration.

Frequently Asked Questions

What AR-pattern rifles is the SBA3X compatible with?

The SBA3X fits any AR-platform firearm that accepts a mil-spec carbine receiver extension (buffer tube). This includes most modern AR-15s, AR-pistols, and short-barreled rifles. The receiver extension itself is not included with the brace.

Can I adjust the length to fit different shooters?

Yes. The SBA3X offers five distinct length settings: 6.75", 7.6", 8.25", 8.75", and 9.5". This range accommodates different arm lengths and allows you to adapt your fit as you change gear (optics, body armor, jackets) without swapping components.

What comes in the box?

The package includes the brace itself and an adjustable nylon strap. The carbine receiver extension (buffer tube) is sold separately and must be compatible with mil-spec dimensions.

Is this legal for my state or application?

Regulations governing stabilizing braces vary by state and federal jurisdiction and can change. SB Tactical designs this product as a forearm brace for supported shooting, not for shoulder firing. You are responsible for verifying your local and state laws and ensuring your firearm configuration complies before purchase.
