Works as intended - Midwest Industries M-Lok Barricade Stop Black MI-MBS

Great little piece and it is quite small; however, it works very well as a hand stop. Equally it doubles well as a barricade stop on my AR-15 pistol, I put it up against a wood particle board wall and emptied a mag, as expected I had no issues staying on target. The serrations, much like those on a meat tenderizer, work well to prevent slippage. The piece is extremely lite and the finish is great. Mounts easily to M-Lok compatible rails and it hasn't loosened yet. One con is the price, $23 for a piece as small as this is a bit steep.
