These pieces were intalled on a Theoben MFR Tactical by Alan. I believe they could be fitted to just about any theoben. It was the full package with rear adjustable butt hook, thigh rest, knee rest, front stabilizer bar with the weight. The front setup was attatched to the gun by a forward rail which is part of the MFR Tactical stock. The rail was replaced on the gun stock by Alan with the size he uses and the whole setup works on the rail. This is the reason I think it could be used on just about any theoben with the installation of a very short rail on the stock. 550 shipped to your door. Conus only, paypal or postal moneyorder.
