Brace that "pistol" - SB Tactical SBA3 Pistol Stabilizing Brace for Mil-Spec Extension Platforms

This is the best "brace" for your "pistol" shoulders well, no noticeably play or movement, easy to adjust. Wanted to give it a 4.9 star review, but, that's not possible. So the only tiny issue... the bottom of the rubber brace, it's not that well supported by the elastic strap and will overlap and move to funky angles eventually. The simple fix, take the two lower parts and fold them inward this shrinks the braces profile a bit and becomes more stable.
