M-LOK Type 2 Half Slot Rail Covers are low-profile, two-piece covers that install directly onto most full and half size M-LOK aluminum hand guards (not compatible with polymer hand guards). Designed to work in conjunction with full size M-LOK Type 2 Rail Covers, Half Slot Rail Covers can be used to fill extra space left by full size Covers and other accessories – allowing for more customization and coverage of your hand guard. M-LOK Type 2 Half Slot Rail Covers are non-orientation specific, which allows the user to mount them in any direction desired without affecting function. The M-LOK Type 2 Half Slot Rail Covers features beveled contours to minimize potential snagging, their TSP texture for additional grip, and protruding just 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 four panels, each covering half an M-LOK slot. Not compatible with Magpul MOE M-LOK, MOE SL and SGA forends, and may not be compatible with free-float handguards that have a wider and flatter profile; they will not seat deep enough to allow the center portion to lock in. Made in the USA.
