Not functional - Bravo Company Mfg MCMR Rail Cover Kit, 5-PACK

These things do look cool, and if you have a MI rail, or BCM, or something with mlok all around, it will look pretty clean if you use these to wrap it. The only problem, which is a big one, is that they dont stay on when firing your weapon to the point of a heated barrel. Once that happens, these tend to start curling and popping off. You can fix it by wrapping some ranger bands around them. But eh, just get some railscales, or if you cant afford those go with magpul II's.
