One Piece Rest - Randolph Machine
The One-Piece Rest The One-Piece Rest (OPR) was, also, designed by Ken Fulghum, to fill the void of a "bag-less" rest. The whole of your rifle "rests" securely in the OPR with the help of adjustable slides on the rear of the rest. One of the added benefits of the OPR is an ammunition tray in the center of the elevation/windage assembly.
