Compact, affordable brace - SB Tactical SBA3 Pistol Stabilizing Brace for Mil-Spec Extension Platforms

I bought this for one of my builds thinking it was cheap enough to just "do the job" until I could file for an sbr. I was surprised to find that I liked this brace so much that I may not go the sbr route at all in the future. This brace adjusts and locks into position just like you want it to without the weird sliding action of the blade style braces. It has QD sling mounts built in too which increases its usefulness.
