Ultradyne UD Double Thumb Rest Grip, Right-Hand

The Ultradyne UD Double Thumb Rest Grip RH (Ultradyne part no. UD20038) is a purpose-built AR-15 pistol grip designed to give right-handed shooters a more consistent, repeatable hold under recoil. Ultradyne builds the grip around a dual thumb-rest backstrap that gives the firing hand two distinct index points instead of one, helping lock the wrist into the same position shot after shot. It drops onto any standard AR-15 or AR-10 grip screw with no gunsmithing required, making it a simple swap for a home-defense carbine, a competition gun, or a hunting rifle. Ultradyne is better known for its precision muzzle devices, and that same attention to ergonomics carries over into this grip.
