SB Tactical SBA4 Brace

The SB Tactical SBA4 Pistol Brace represents an evolution of the popular SBA3 design with enhanced rigidity and improved cheek weld support. At 8-10 ounces (sources vary), the SBA4 is slightly heavier than the 6.75-ounce SBA3 but provides significantly better stability and a larger cheek weld area. The 5-position adjustable design accommodates different shooter sizes and preferences.

The SBA4 features a much more rigid rubber strap section compared to the SBA3's flexible design, providing enhanced support and stability. The QD sling swivels are located toward the front of the brace (versus rear on SBA3), and the overall length ranges from 7.5 to 10.25 inches across five positions. The SBA4 measures 7 inches overall while the SBA3 is 6.75 inches, with the SBA4 offering more surface area for better contact and control.

Users consistently note that the SBA4 feels more stable and offers superior cheek weld compared to the SBA3. The increased rigidity and larger contact area make it better suited for shooters who prioritize stability over minimal weight. While heavier and more expensive than the SBA3, the SBA4 delivers enhanced performance that justifies the upgrade for many AR pistol owners seeking maximum control and consistency.
