Geissele Super Modular Rail MK4 M-LOK 15" Black
Factory Blemished Product
Does not include the gas block. All installation hardware, barrel nut and wrench are included.
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 2.25" 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.
This product is labeled "BLEM." Charlie's has inspected each Geissele factory blem, and there are some discoloration areas, some of which might be visible on immediate inspection, and others you have to really look for. Geissele runs a great quality factory, and the real rejects go back into recycled Budweiser cans and never leave the factory with a Geissele name.
Note: Includes Geissele factory barrel nut, hardware and wrench. Does not include a gas block.
