Geissele 13" MK4 M-Lok Super Modular Rail, DDC ‒ 05-278S
*Does not include gas block and barrel nut wrench.
The Super Modular Rail (SMR) MK4 M-LOK™ is Geissele’s ultra-combat M-LOK option. These rails are purpose-built and feature integrated M1913 picatinny rail sections at the fore end of the rail in the 3, 6 and 9 o’clock positions. Maximum venting for heat dissipation also dramatically reduces the rail’s overall weight, while maintaining its same strong and rigid platform. Utilizing Magpul’s M-LOK technology at the 3, 6, and 9 o’clock positions, as well as the upper 45° quadrants, the SMR MK4 is both versatile and modular, allowing the user to tailor their platform to his or her unique needs. The SMR MK4 also features Geissele’s proprietary 21/4” 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.
