M-LOK Offerings Grow With ALG Defense’s EMR Rails

    M-LOK is the new kid on the block in the rail interface market, but Geissele Defense and its sister company ALG Defense have been quick to embrace the new standard. Announced on ALG’s Facebook page on the 11th, the company is now offering their low-cost Ergonomic Modular Rails (EMR) in the new M-LOK standard.


    Note the difference in profile between the standard and low-profile “co-witness” rail sections. The co-witness are designed to match up with a standard flat-top receiver.

    The EMR rails are available in 10, 12, and 13-inch flavors. All are available in black with the 13″ version also available in the DDC color scheme (Desert Tan). ALG looks to be making all the lengths available in their standard colors (Black, Grey, Tan, & Purple) in due time.

    The combination of manufacturing techniques (extrusion & machining) and materials (aluminum) make the rails lightweight. The 13″ rail is 8.06 oz. bare and a scant 10.46 oz. with the barrel nut mounted to a rifle.


    The rails are a veritable bargain.  Rails run $100, $110, and $115 for 10, 12, and 13″ versions, respectively. Each includes the barrel nut, wrench, shims, and screws to mount the rail. ALG M-LOK accessory rails are also available for $20 each. They are available in low-profile “co-witness” and standard profiles.
