Geissele MK4 13 Inch Super Modular Rail MLOK Free Float Handguard For AR15 Style 5.56/.223 Rifles - Black
The Super Modular Rail (SMR) MK4 MLOK is Geisseles ultra lightweight MLOK option. These rails are purpose built and feature integrated M1913 picatinny rail sections at the fore of the rail in the 3, 6 and 9 oclock positions.
Maximum venting for heat dissipation also dramatically reduces the rails overall weight, while maintaining its same strong and rigid platform. Utilizing Magpuls MLOK technology at the 3, 6, and 9 oclock positions, as well as the upper 45 quadrants. The SMR MK4 is both versatile and modular, allowing the user to taylor their platform to his or her unique needs.
The SMR MK4 also features Geisseles proprietary 2.25 inch 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. Bundled with a low profile Geissele Super Gas Block, a $59 value, the SMR MK4 is not only feature packed, but it is also value packed.
