Super Modular Rail MK4
The Super Modular Rail (SMR) MK4
M-LOK™ is Geissele’s ultra-lightweight M-LOK 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 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 2" 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.
