Abstract

Abstract A bullet drop compensating telescope mount having a front mounting ring pivotally mounted to the rifle and a rear mounting ring for vertically adjusting the telescope position therein by means of an adjusting screw having a thread pitch corresponding to a bullet weight to be fired from the rifle. A dial graduated in distance increments is attached to the adjusting screw, and a pair of positioning pads limit lateral movement of the telescope in the rear mount.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 228 words
A bullet drop compensating scope mount comprising, in combination: front and rear scope supporting rings each having separable upper and lower halves, enabling a scope to be mounted therein; the front ring internally sized to grippingly lock on a scope to prevent relative motion between the scope and ring; means for mounting said front ring on a rifle for fore and aft rocking motion about a transverse pivot; the rear ring internally sized to allow relative vertical and lateral movement of a scope embraced thereby when such ring is mounted on a rifle; means on the rear ring for vertically adjustably positioning a scope therein, characterized by a dial graduated in distance increments and a vertical adjusting screw having a thread pitch corresponding to a determined bullet weight to be fired from a rifle on which the scope is mounted, with the dial connected to the screw; a pair of positioning pads within the rear ring disposed on opposite lateral sides of a scope mounted in the ring with one of the pads being laterally adjustable and disposed against the scope and the opposite pad spaced closely from the scope for limiting lateral movement of a scope; and a resilient element in the rear ring for urging a scope embraced by the ring against said one pad and against said adjusting screw to hold the scope continually thereagainst.
