The SB Tactical SBA3X pistol stabilizing brace is built for shooters running AR platforms with mil-spec carbine receiver extensions who want a more stable, controllable hold without the complexity of a traditional stock. This ambidextrous brace features a minimalist design that gets out of your way while delivering genuine wrist support—it's the kind of upgrade that makes a noticeable difference in how your pistol-caliber or short-barreled rifle feels in your hands, whether you're at the range, hunting, or running drills.
Designed and made in the USA by a veteran-owned company, the SBA3X gives you real adjustability: five different length positions let you dial in the fit for your arm, gear configuration, or shooting stance. The integrated, ambidextrous QD sling socket means you can run a sling without hunting for attachment points or bolting on extras. What you get is clean, purposeful design—no fluff, no unnecessary bulk. The adjustable nylon strap cinches down to keep the brace where you need it, and at under 7 ounces, it won't throw off your rifle's balance.
Available in black or FDE (Flat Dark Earth), the SBA3X accommodates a wide range of arm sizes and fits over light gear, making it versatile enough for different shooters and loadouts. The brace mounts directly to any mil-spec carbine extension tube, so if your AR already has one, you're ready to go—no special tools or additional parts required beyond what's in the box.

The SBA3X is designed for any platform equipped with a mil-spec carbine receiver extension. Your AR platform needs to already have a standard mil-spec tube for the brace to mount; the extension itself is not included with this product.
Yes. The SBA3X offers five adjustable length positions (6.75", 7.6", 8.25", 8.75", and 9.5"), so you can dial in the fit for your arm length, body armor, or tactical gear. The adjustable nylon strap helps keep it secure once you've set your preferred length.
The SBA3X includes an integrated, ambidextrous QD (quick-detach) sling socket molded into the brace itself. You can run a standard QD sling attachment without adding extra hardware—it's built in and works from both sides.
SB Tactical designs this product as a forearm brace for stabilizing the firearm platform; it is not designed or intended to be fired from the shoulder. Since firearm classification can change based on configuration, the user bears sole responsibility for determining compliance with all state and federal laws governing their specific setup.
