Great brace - SB Tactical SBA4 Stabilizing Brace for Mil-Spec Carbine Extension Platforms

This brace fits nice and snug on the buffer tube with no rattle. The weight of it helps offset the rest of the gun. The fins don’t split at all like they do on the SBA3. I do wish that the strap was a little longer. I like that the QD point is farther forward. It helps keep the gun closer to your chest when running the sling mount on the opposite side of the brace.
