M-LOK Type 2 Rail Covers are low-profile, two-piece covers that install directly onto most M-LOK aluminum hand guards (non-polymer). This pack of six M-LOK covers is non-orientation specific, which allows the user to mount them in any direction desired without affecting function. Not compatible with MAGPUL MOE M-LOK, MOE SL and SGA forends, and may not be compatible with free-float hand guards that have a wider and flatter profile, as they will not seat deep enough to allow the center portion to lock in.
