This is my first time using a shooting tripod that vice-locks my rifle into the mount. I've seen these at long range shooting matches and found that BOG sold a tripod head that converts your photo tripod as well as a complete tripod unit. and The BOG Deathgrip Ultralight tripod adapter and the BOG Great Divide turns a photo tripod into a rifle tripod mount. The Deathgrip worked as well as intended but the Great Divide wasn't able to hold my 4.5lb Sub2K carbine despite tightening it down as best I could.
