Super Modular Rail MK13 M-LOK®
The MK13 is the latest entry to the Geissele line up of Super Modular Rails. The new handguard design offers a smaller diameter and overall height to create a slimmer package. Included with the MK13 Super Modular Rail is an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but superior rigidity. The long surface contact of the 2.25” barrel nut interfaces with the receiver creating a platform that can be trusted to be straight and true the entire length of the free float rail. The MK13 is precision machined using 6061-T6 aluminum due to its strength, rigidity and lightweight properties.
Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions and machined-in Picatinny rails at the end allow the end user to customize their rifle and securely mount lights, bipods and other firearm accessories. The Geissele MK13 Super Modular rail is finished in a durable and long lasting Type 3 Anodized Hardcoat 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 SMR MK13 a comfortable, rigid, value packed and high quality rail system developed for AR15 pattern rifles.
good stuff.... - Scott
this 13" Mk13 really is light... frontal real-estate is plenty for lights, sights, bipods..... weight is kept down by only having the front 3,6,9 mlok.... which also makes for multiple grip positions since its a little thinner..... definitely looking to get another.November 13th, 2018

Modern Upgrade - Todd
I have this on my DD MK18 Pistol. Hot Damn this thing is slick. Smooth and light able to work it faster in transition drills. Its slimmer and lighter than the RIS 2 that DD makes so my overall grip while shooting feels tighter and easier to maintain over a longer period of shooting. The overall quality is good can not speak of durability yet.April 27th, 2018
Wow - Michael
Pictures do not do this rail justice! It is a work of art! Even the top rail has vents cut in it! Your rifle will not be getting hot with this rail! You won't be disappointed!May 20th, 2017
