The AR-MREX was developed after the original KDG FN Scar MREX. At first glance it may look similar to other AR rails on the market, but like the MREX developed for the FN SCAR, there was purpose in its design. The MREX-AR is ergonomically set up to be more like a handguard instead of a tube. The profile allows the user a very comfortable C-Grip on the weapon and allows those accessories to be mounted as though they are integral to the weapon. The flat bottom of the rail system is ideal for shooting off of support. The MREX-AR is a free float design, and simple to install. Featuring M-Lok on the 3" 6" and 9 O'clock positions as well as offset 45degrees offset M-Lok above the 3 and 9 O'clock segments, and a full length monolithic standard 1913 picatinny rail on top.
