Over the years we’ve gotten thousands of 5 star reviews on the NBS line of complete uppers, we’re sure that this premium variant will go fast. About the Handguard The Super Modular Rail (SMR) MK8 M-LOK is Geissele’s ultra-modular model. These rails are designed to give the user full modularity while maintaining a strong and rigid platform. Maximum venting at the lower 45 quadrants create maximum heat dissipation and also dramatically reduces the rail’s overall weight. Utilizing Magpul’s M-LOK technology at the 3, 6, and 9 o’clock positions, as well as the upper 45 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 Geissele’s 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.
