Geissele Automatics MK4 M-LOK 10.5" Super Modular Rail

Give your rifle a rugged M-LOK® rail option with the Geissele Automatics® MK4 M-LOK 10.5" Super Modular Rail. 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. Even better, this handguard boasts maximum venting for heat dissipation and to help dramatically reduce the rail's overall weight for better and more intuitive control as well as improved accuracy with your favorite rifle. Plus, the SMR MK4 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 features 7000 series aluminum construction with a Type III anodized hardcoat corrosion-resistant finish so it can take tough use and abuse at the range or in the line of duty. Backed by a limited lifetime warranty from Geissele. Compatible with mil-spec M4 upper receivers. Compatibility with billet receiver sets is unknown. Order now!
