Height adjustable rear grip aiming support for a firearm

Abstract

The present invention relates in general to the field of firearms, and more specifically, to a height adjustable rear grip aiming support for a firearm. The rear grip aiming support may be integrated into an existing rear grip screw hole and chamber of a firearm without having to modify the firearm. The rear grip aiming support includes a tuning pad in cooperation with a height locking wheel and a threaded stud to provide very fine height adjustment tuning to the rear grip of the firearm when it is resting upon a shooting surface (e.g., ground or table). Such fine control provides the accuracy required to place the firearm on target when shooting at long distances. The purpose of the invention is to provide a rear grip aiming support that ultimately improves the accuracy of shooting a firearm while reducing a shooter's fatigue.
