True North Concepts M-LOK Polymer K Length GripStop Olive Drab. The original GripStop was first released in 2013 after years of research and design. Created by a Marine combat veteran the GripStop will benefit a wide variety of different shooting styles and firearm types. The GripStop K is smaller than a vertical grip but larger than a hand stop. Our K model is 1 shorter than the fullsize GripStop for those looking for a smaller profile. The GripStop was the first product to properly address correct shooter ergonomics. The unique serrated front radius allows the shooter to pull the firearm rearward into the shoulder pocket and maintain a solid hold on the gun with the support hand. This feature also works great as a barrier-stop against walls rock automotive frames and barricades. The GripStop and GripsStop K has been combat-proven by American Special Operations Forces and Marines in multiple combat theaters and will survive the toughest abuse.
