Stark Equipment MPX Rifle Grip MPX Swivel Mount Earth. Compatible with all SIG MPX models this grip provides an extended length and smoother material flow resulting in a more positive anchor point for your hand. In addition the material blends seamlessly with the OE grip replacing it as if it were molded in place. This results in a sleek customized appearance for your SIG MPX Rifle. In order to accommodate for the differences in hand measurement between shooters of the SIG MPX the grip has been designed with a single finger groove. The material is tough yet won't crack warp or rot like some other molded AR grips on the market. The profile is kept thin to avoid contact with the knuckles on the SIG MPX but still retains enough knuckle thickness to provide a positive anchor point and improve control of the rifle.
