After four years of hard use, Kinetic Development Group has taken every lesson learned from users of their popular MREX rail system to heart. These lessons have been turned into improvements now available in the MREX MKII. M-LOK slots now run the entire length of the rail, and more have been added at the 10 and 2 o'clock positions for increased accessory options as well as protection from blistering hot gas blocks. Best of all, the MREX MKII is now easier to install. Give your SCAR a face lift with the M-LOK Receiver Extension MKII!
