The rock-solid Reaper Grip Upper Assembly is an easy add on accessory, yet essential for mounting directly on top of a ball-joint style tripod system with 3/8-16 threaded stud provides the same unshakeable stability as the Reaper Grip system. With no comparisons the Reaper Grip maximizes proper shooting techniques outside of the supported prone position. The Reaper Grip will anchor down most tapered and straight stocks and chassis with the non-slip grip sleeve. The Reaper Grip Upper Assembly also includes a thread insert to mount on ¼-20 inch threaded studs.
