The Geissele 15" Super Modular Rail MK4 M-LOK is an ultra-rugged, lightweight free-float handguard engineered for maximum strength and modularity on AR-15 platforms. 3D machined from a solid block of 7000-series aluminum, it features integrated M1913 Picatinny rail sections at the 3, 6, and 9 o'clock positions at the front, full M-LOK compatibility along the sides and bottom, and maximum venting for superior heat dissipation while maintaining exceptional rigidity.
This rail offers a perfect balance of weight savings and durability with a low-profile design that sits close to the barrel for improved balance and handling.
