The Ergo WedgeLok 4-Slot M-LOK Slot Cover (Ergo part no. 4332BK) is a low-profile rubber cover built to clean up a run of exposed M-LOK slots on any AR-15 or AR-style handguard. Molded from durable black rubber, each cover spans four adjacent M-LOK slots at once and adds an aggressive, non-slip texture that gives your support hand a secure gripping surface along the rail. Shooters running M-LOK handguards use these to fill unused accessory space, guard against snagging on gear, and add texture without bolting on a bulky rail panel. This listing includes four of the 4-slot covers, enough to finish out a full-length handguard in one order.
