The Firefield Verge 12" M-LOK Rail provides a way to mount lights, aiming lasers, optics, and night vision gear on your rifle, while providing a comfortable grip. The rail is made of lightweight, hard anodized 6061-T6 aluminum and features a Picatinny rail along the top, plus a separate 7-slot Picatinny rail that you can position as needed. An AR-15 armorer wrench and a torque wrench are required for installation; if these tools are not available, it is best to have the M-LOK rail installed by a gunsmith.
