FAB Defense MALC-1 Locking Rail Cover Slim M-LOK 9-Pack

The FAB Defense MALC-1 is a slim M-LOK-compatible locking rail cover sold in a 9-pack, designed to protect unused rail sections, enhance grip, and reduce snagging on any M-LOK-spec handguard.

Built in a low-profile black finish, each cover installs quickly with a secure locking fit into standard M-LOK slots, giving your rifle a clean look while filling empty rail space. The slim profile measures approximately 1.54 in long by 0.73 in wide per cover, keeping the handguard snag-free while adding subtle tactile surface without adding bulk to the firearm.

Beyond rail protection, the MALC-1 also acts as a heat shield, helping block heat transfer from a hot handguard while keeping debris out of open M-LOK slots. The pack of nine gives you enough covers to fill every unused M-LOK slot on a single full-length handguard or to cover multiple rifles.

Your purchase includes a 9-pack of MALC-1 slim locking rail covers for M-LOK handguards.
