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, our TSP texture for additional grip, and protruding just 1/8" from the mounting surface to maintain its low-profile. Includes six 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.
