NEW!! Geissele SMR MK4 M-LOK Rail

Posted on January 15th, 2015 by ar15news

One of my favorite rails I have is the Geissele SMR MK4 which features some KeyMod slots at the 3, 6 and 9 o’clock sections as well as short rail sections up front. They now are offering the SMR MK4 with M-LOK slots. The coolest part is that they also put M-LOK slots along the upper left and upper right 45 degree angles allowing for additional mounting positions that are tucked in closer to the top rail. 

As with all of the Geissele Super Modular Rails, the MK4 M-LOK will mount to Geissele’s proprietary barrel nut that makes for an extremely rigid transition from Upper to Rail and also makes it very easy to swap out different rails on one single upper. So far there is no exact time for when these will be available but I would assume they’ll be available soon.

The Super Modular Rail MK4 M-LOK is Geissele’s ultra-lightweight M-LOK option. These rails feature integrated M1913 Picatinny rail sections at the muzzle end of the rail in the 3, 6 and 9 o’clock positions. Additional slotting aids in heat dissipation while dramatically reducing the rails overall weight and not sacrificing the original strong and rigid platform. The MK4 M-LOK rail features M-LOK slots at the 3, 6 and 9 o’clock positions as well as the upper 45° quadrants. This reduces weight of the rail system, while keeping the modularity and versatility to attach the myriad of Magpul M-LOK of accessories as necessary.
