Abstract: The present invention relates to improvements in a power rifle scope of the type having a tubular housing barrel with enlarged end portions and an optical axis defined by an optical system including an objective lens disposed in the enlarged front end thereof, an eyepiece lens system disposed in the enlarged other end thereof and an erector lens system intermediate the said two ends and where the improvement comprises the addition of a variable optical aperture mounted in and carried by a cylindrical guide tube which is secured interiorly of the scope barrel, a helically rotatable setting ring carried by and disposed exteriorly of the barrel and having an inwardly radially directed actuating pin which passes through the barrel and through a circumferential slot in the guide tube and operatively engages the variable aperture device to vary the light passing capacity of the barrel in response to rotation of the setting ring and sealing rings disposed between the setting ring and the barrel, for and aft of the a

Abstract: This invention relates to an improved laterally-adjustable ring-type riflescope mount for attachment to rifle barrel receivers of the type having a one part of a dovetail connection atop thereof defined by a planar top surface alongside of which lie a spaced parallel pair of upwardly-divergent longitudinally extending groove walls, said mount being characterized by a base having a planar bottom wall adapted to rest upon the top surface of the receiver in supported relation, a pair of sidewalls, a pair of upwardly and inwardly-convergent internally-threaded sockets in the sidewalls each having the axis thereof perpendicular to their respective upwardly-divergent dovetail groove walls, and a pair of large-headed screws screwed into the sockets with the heads thereof overlapping the upwardly-divergent groove wall lying in opposed relation thereto, these screws cooperating with one another when screwed in tight against the divergent dovetail groove walls to hold the base down snugly atop the receiver, and these s

Abstract: This invention relates to a variable-power riflescope equipped with a novel range-compensating reticle system characterized by separating the horizontally-disposed element thereof from the vertically-disposed one, locating the former in the forward focal plane displaced off the optical axis and locating the latter in the rear focal plane while, at the same time, displacing the aiming point carried by the latter off the optical axis also. The resulting reticle system functions in cooperation with the means for varying the degree of image magnification in such a way that the shooter is enabled to precisely define two ranges, one near and one far, and shoot quite accurately at any distance therebetween. A further refined version of the same system allows the shooter to actually determine the range to a chosen target of known dimension an unknown distance away and in so doing automatically adjust the aiming point defined by the reticle system to coincide with the point of impact of the bullet.

Abstract: This invention relates to a reticle for riflescopes and the like having crossed filaments defining the aiming reference, the center sections of such wires being flattened in a direction parallel to the viewing axis.
