Geissele 15" Super Mod Mk8 Mlok Blk

The Super Modular 15" Rail (SMR) MK8 M-LOK is Geisseles ultra-modular model. The SMR MK8 is one of the first rails available to utilize the Magpul M-LOK technology. These rails are designed to give the user full modularity while maintaining a strong and rigid platform. Maximum venting at the lower 45 degree quadrants create maximum heat dissipation and also dramatically reduces the rails overall weight. Utilizing Magpuls M-LOK technology at the 3" 6" and 9 oclock positions, as well as the upper 45 degree quadrants. The SMR MK8 is both versatile and modular, allowing the user to tailor their platform to his or her unique needs. The SMR MK8 also features Geisseles proprietary 2.25" long barrel nut. This increases the surface contact where the rail interfaces with the receiver and creates a platform that can be trusted to be straight and true the entire length of the free float rail. This increases accuracy and zero repeatability during disassembly and reassembly when performing maintenance.
