Similar in concept to the MOE-K, the MOE-K2 is a drop in upgrade for the AR15 / M4 that offers a more vertical grip angle, but in a full-size grip design. The steeper vertical grip angle is optimized for use on PDW configurations and improves comfort and control on short LOP rifles that bring the primary hand in closer to the shooter's body.
