Geissele Automatics MK4 M-LOK Super Modular Rail

The Geissele Automatics® MK4 M-LOK® Super Modular Rail is the ultimate rail system for your new rifle build, featuring 7000 series aluminum construction with a Type III anodized hard coat finish for long-lasting corrosion and abrasion resistance. This handguard is specifically designed with integrated M1913 Picatinny rail sections at the fore end of the rail in the 3, 6, and 9 o’clock positions to give you plenty of room and versatility when attaching your favorite weapon-mounted accessories. What’s more, this rail also utilizes Magpul® M-LOK technology at the 3, 6, and 9 o’clock positions as well as the upper 45° quadrants to be the most versatile and modular handguard so users can tailor it to their specific and unique needs. The MK4 M-LOK Super Modular Rail boasts maximum venting for heat dissipation and helps dramatically reduce the rail's overall weight for better and more intuitive control as well as improved accuracy with your favorite rifle. This rail also features a proprietary 2.25” long barrel nut that helps increase the surface contact where the rail interfaces with your rifle’s receiver for a secure, wobble-free fit. Further, this rail is backed by a limited lifetime warranty from Geissele. Compatible with mil-spec M4 upper receivers. Order now!
