Good, but could be great. - SB Tactical SBPDW Pistol Stabilizing Brace for Mil-spec AR-15 Receivers

Overall it's an awesome product but could be a little better. There's a little slop but not too bad. It's pretty comfortable. However before I got this I had a phase 5 buffer tube and was quiet and couldn't hear the spring at all. I installed the PDW brace and the spring sounds absolutely terrible now. So the machining inside the tube to be alot better than it is. That's about the only thing that I don't like about it.
