CMMG 7-Slot M-LOK Accessory Rail Kit

The CMMG 7-Slot M-LOK Accessory Rail Kit lets you mount standard 1913 Picatinny accessories directly to your M-LOK handguard without drilling, replacing, or retrofitting. If you're running an AR or other modern rifle with M-LOK slots and want to add lights, lasers, backup iron sights, or other rail-mounted gear, this is a clean, reversible way to do it. The kit includes everything you need to get mounted.

M-LOK has become the go-to lightweight alternative to full-length picatinny rails, but it limits your accessory choices to M-LOK-specific mounts—or you use an adapter like this. CMMG's 7-slot rail section bridges that gap, giving you access to the full universe of Picatinny-mounted tools without compromise. Mount it where you need it, remove it if you don't, and keep your handguard lean.

Real-world use: hunters and shooters who've invested in Picatinny accessories (proven lights, magnifiers, offset sights) don't want to rebuy everything in M-LOK flavor. This kit is the practical solution. It's also useful if you're building a rifle with mixed-generation parts or if you prefer the ergonomics and lower weight of M-LOK slots but already own quality Picatinny optics and gear.
