yeah dude move that light back. Less contact will increase your chance of that 300$ light sailing off the gun under recoil

In my experience BCM makes incredibly made and well thought out gear. They don't seem to releaee crap "just because" or to make a few bucks, it seems to have a well designed purpose for end users.
