The SB Tactical SBA4X-02-SB is a 5-position adjustable AR-platform brace built for shooters who need a stable, comfortable fit without compromise. Designed with input from US veterans and manufactured domestically, this stabilizing brace delivers the adjustability you need to dial in your setup across multiple shooting positions and body types. The synthetic flat dark earth construction is lightweight and rugged—ideal for shooters running pistol-caliber uppers, short-barreled rifles, or any AR platform that accepts a mil-spec carbine extension tube.
Length matters when it comes to brace fit, and the SBA4X gives you five positions spanning from 7.5" to 10.25", so you can find the exact length that works for your grip and stance. The integrated ambidextrous QD sling socket keeps your setup flexible for sling attachment, while the included adjustable nylon strap provides additional support and control. At 10 ounces, it won't burden your carbine or pistol, and the 1" strap width distributes pressure evenly across your support side for extended shooting sessions.
Whether you're running a home defense setup, a competition rig, or a compact hunting platform, the SBA4X adapts to your needs. The flat dark earth finish blends seamlessly with most modern tactical furniture, and the proven SBM4 design ancestry means you're getting a pattern trusted by thousands of shooters. If your AR-pattern upper accepts a standard mil-spec extension tube, the SBA4X will fit.

The SBA4X comes with the brace itself and an adjustable nylon strap. No additional installation hardware is required if your carbine tube is already set up.
The brace offers five adjustable positions: 7.5", 8.25", 8.8", 9.5", and 10.25". Start with a mid-range position and adjust to match your preferred grip, stance, and body geometry for optimal control and comfort.
The adjustable length and integrated strap make the SBA4X versatile enough for multiple shooting positions. The five positions let you dial in the fit that works best for your intended use.
