Very nice addition - FAB Defense Rubberized M-LOK Compatible Versatile Tactical Support

I mounted this on an AR 15 pistol. It took some trial and error to find the right placement. It helps more than you'd think with the shorter barrel as I have a difficult time with just the pistol stock. Since most of my rifles are full length my left hand just naturally wants to go to its place, like after changing a magazine. I've gotten a rude burn once or twice. Now with this addition after changing mags, my left hand slides up the handguard from the mag well till it hits the support, I'm in the desired firing position, and my left hand doesn't reach the 'danger zone' of hotness. Its nothing fancy but it does the trick, and as far as I'm concerned its a few bucks well spent.
