ABSTRACT:
A quick detachable improvement upon scope mount systems having a front mount allowing swiveling in the horizontal plane is disclosed. The rear mount and base of such scope mount systems are modified. The concavoid inner surfaces of the latching means mate with the convexoid surface machined into the same side of the bottom portion of the rear mount around a bore traversing horizontally through the upper portion of the base when the rear mount is positioned into the zeroed position, the bore being positioned below where the upper flat surface of the base abuts the flat surface of the rear scope mount. The second latching member of the improvement is truncated on a plane parallel to the bore through the base, and preferably has a lever means integral therewith such as to permit quick release of the rear mount and detachment of the scope by swinging out so as to detach the front mount. The improvement is applicable to a number of popular scope mount systems on the market.
