Our eBay Store Magpul M-LOK Low-Profile Type 2 Rail Covers MAG603 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. Featuring beveled contours to minimize potential snagging, our TSP texture for additional grip, and with a protrusion only slightly more than 1/8" from the mounting surface to maintain its low-profile. The center locking tab is pre-scored to allow the user to snap off sections and mix and match colors for a customized look. Includes six panels, each covering one M-LOK slot.
