The GripStop-K2 is a K-size/shorter version of our GripStop Standard. The K2 uses a smaller, single M-Lok slot footprint compared to its Standard and K brothers. The K2 is built from domestically sourced 6061-T6 Aluminum with our standard Milspec Anodized Type 3 Hardcoat. The latest addition to the GripStop family is tough, reliable, and not too bad on the eyes. All GripStops carry the same lifetime "No questions asked" replacement warranty and is built with military application at the forefront of its design.
