Its great for a pistol brace but sb3 is better - SB Tactical SBA4 Stabilizing Brace for Mil-Spec Carbine Extension Platforms

ok so I had to get the SB4 because the SB3 was on backorder.... thanks CoVid! Its super nice ... to look at and used while shooting, but couple of bad things. #1 I haven't seen anyone else with the same problem but the pin that locks the length of pull in is misaligned or something. It either wobbles or won't lock in place. It's incredibly inconvenient but I can make it work. #2 there was some of the edges (looks like where the mold went together) were very jagged with extra plastic. #3 this is about the design not quality. So just FYI its not very comfortable to strap to your arm. I think this design is more for using against the sholder not on one arm. It dose offer some extra strength for recoil mitigation. Just for anyone who needs to use this with one arm the SB4 is not the way to go.
