#GV30 MTM Gun vise The MTM Gun Vise was designed to accommodate a wide array of firearms for gun cleaning, maintenance, or gunsmithing, and is for rifles and shotguns. All firearm touch points are rubberized to protect your guns finish. The second fork behind the clamp is for cleaning guns, so that they will have proper angle for cleaning. The 11 compartments in the base can be used for separating gun components or anything you choose. 21 screw driver bit holders, molded to the unit, are as easily suited for jags and brushes as they are bits. Made of rugged, chemical and solvent resistant polypropylene plastic, the MTM Gun Vise is made to last!
