This ambidextrous vertical grip is a simple, lightweight and cost-effective device which secures tightly to any M-LOK mounting system. The low profile vertical grip design provides a positive hand hold in a small package. Adequately sized to allow the hand to take control of the front of the rifle, but not large enough to get in the way. Features: Black finish M-LOK grip without storage compartment 2.95 inches height Includes Allen wrench
