16" Super Modular Rail MK18 M-LOK®
The MK18 is the latest in the line of Geissele Super Modular rails and is specifically made to interface with the Arca-Swiss Quick Release System. This new handguard is based on the MK16 M-LOK Super Modular Rail, offering a small diameter and overall height creating a slim profile for competition shooters. The flat base of the MK18 features an “Arca-Style” 35mm wide form with a 45 degree dovetail, that allows quick mounting to an Arca-Swiss Quick Release mounting base, sliding into any position along the rail. The MK18 features Geissele’s proprietary 2.25” long barrel nut that 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. The 16” long MK18 is 3D precision machined using 6061-T6 Aluminum due to its strong, rigid and lightweight properties.
Utilizing Magpul’s M-LOK technology at the major 3 quadrants (left, right and bottom), as well as the upper 45’s gives the MK18 unprecedented modularity and ability to be customized. The MK18 Super Modular rail is finished in a durable and long lasting Type 3 Hardcoat Anodize available in either Black or Geissele’s DDC finish.
This product is bundled with a low-profile Geissele Super Gas Block, a $59 value, and an installation wrench, making the Geissele SMR MK18 a high quality and value packed solution for the Arca-Swiss Quick Release system. The Geissele Super Modular Rail MK18 is compatible with AR15 pattern rifles.
Nice rail! - Justin
Been impressed with this rail so far! Fit and finish are impeccable as usual and installation was a breeze.October 8th, 2018
Tons of real-estate for mounting whatever needed and my RRS adapter (for 17S bipod) fits without issue.
Even with its wide ARCA-Swiss bottom it is still comfortable to shoot offhand when needed. And this wide bottom makes it easy to shoot off a bag.
All in all definitely a winner and highly recommended for any 18"+ precision rig.

Picked up the Mk18 rail for the full length integrated 1.5 dovetail. Using an Atlas bipod with a Really Right Stuff BTC-PRO Clamp you can quickly slide the bipod to any position based on the size / type of barricade.September 25th, 2018
Based on the photos the rail looked beefy so was concerned about the weight initially. It’s not nearly as heavy as I expected but remains extremely rigid. If you’re building an SPR / DMR, 3-gun, PRS gas gun or varmint rifle in an AR-15 platform then this is the rail to get.
