Enhanced Performance

The CMC M-LOK Picatinny rail mounting system allows you to mount desired accessories exactly where you need them on your AR platform without removing the handguard from the upper. The universal system is designed for use with all M-LOK compatible metal or polymer accessories and readily accepts many Picatinny spec accessories such as foregrips and lights.

Quality Construction

The CMC M-LOK Picatinny rail is machined from mil-spec 6061-T6 anodized aluminum for lightweight and durability. The rail weighs as light as 0.5 ounces with a .08-inch width and is protected by a hardcoat anodized matte-black finish. These rail sections have beveled ends that eliminate sharp corners and edges to reduce the potential for clothing, straps, and other objects snagging on the rail.

Easy Installation

The CMC M-LOK Picatinny rail attaches easily with no special tools or gunsmithing experience, and all hardware needed for mounting is included.
