The KeyMod system uses a system of keyholes, similar to one you’d find on a door chain. How said M-LOK or KeyMod accessories mount depends on whether KeyMod vs M-LOK is the system you’re using. M-LOK and KeyMod direct attachment systems let you bolt whatever you want directly to the gun. Why are they better than a rail? Picatinny rails require extra metal and therefore add weight.

The compatible accessories of your choice is mounted to a bracket that locks into said holes.ĭepending on the handguard, you can mount accessories on the sides, bottom or top of the handguard. Both systems are designs holes machined into the handguard instead of to said rail. How they work differs from your typical Picatinny rail, though plenty of M-LOK and KeyMod handguards have a Picatinny rail as well.
