A riflescope includes an objective lens component slidably supported on a guide track oriented perpendicular to an optic axis of the objective lens component for lateral, non-pivoting movement of the objective lens component in or along a plane perpendicular to the optic axis. Movement of the objective lens component shifts an image of a target in the field of view relative to an aiming mark displayed in the riflescope. In a preferred embodiment, a transparent optical window is fixedly mounted forwardly of the objective lens element and sealed to the riflescope housing.

The invention claimed is: 1. A riflescope mountable to a weapon and having a field of view, comprising: a housing; an eyepiece mounted at a first end of the housing; a transparent optical window fixedly mounted at a second end of the housing opposite the first end; a guide track positioned within the housing between the first and second ends, and proximal of the transparent optical element; an objective lens system comprising at least one objective lens component, the objective lens system being operative to form a forward-most image at a forward-most focal plane of the riflescope, the objective lens component (a) having an optic axis, (b) being disposed entirely in front of and distal to the forward-most focal plane, and (c) being slidably supported on the guide track for lateral, non-pivoting movement of the objective lens component relative to the housing along a plane perpendicular to the optic axis; an aiming mark displayed in the field of view; and an adjustment mechanism operatively engaged with the objective lens component for driving the objective lens component laterally along the guide track in a straight line and along a direction perpendicular to the optic axis of the objective lens component to thereby shift an image of a distant target relative to the aiming mark in order to compensate for ballistic elevation or windage. 2. The riflescope of claim 1, wherein the adjustment mechanism includes: a rotatable adjustment knob; and a plunger operatively coupled to the adjustment knob so that rotation of the adjustment knob drives the plunger along an axis of travel parallel to the plane of movement of the objective lens component. 3. The riflescope of claim 1, wherein the aiming mark is embodied in a reticle part mounted within the housing between the objective lens component and the eyepiece. 4. The riflescope of claim 1 further comprising: an erector system located between the objective lens component and the eyepiece for erecting an image produced by the objective lens component. 5. The riflescope of claim 4, wherein the erector system includes a prism erector system. 6. The riflescope of claim 1, wherein the objective lens component is slidably supported within the housing for movement along a vertical path to thereby achieve an elevation adjustment of the riflescope. 7. The riflescope of claim 1, wherein the objective lens component comprises a primary objective lens element, the riflescope further comprising a secondary objective lens element positioned between the primary objective lens element and the eyepiece, and spaced apart from the primary objective lens element. 8. The riflescope of claim 1, wherein the window and the eyepiece are sealed to the housing to maintain a fog-inhibiting dry gas charge within the housing. 9. The riflescope of claim 1, wherein the objective lens component is mounted on a lens carriage that is slidably guided on or in the guide track, and the adjustment mechanism drives the carriage for movement along the plane. 10. The riflescope of claim 9, wherein the lens carriage is made of a plastic material to reduce friction between the lens carriage and the guide track. 11. The riflescope of claim 9, wherein the guide track includes a rear-facing bearing way against which the lens carriage is biased and free to slide along the plane responsive to adjustment of the adjustment mechanism. 12. The riflescope of claim 1, further comprising a second adjustment mechanism driving the objective lens component for lateral, non-pivoting movement along a second straight line perpendicular to the straight line and the optic axis. 13. The riflescope of claim 1 including a focal plane, and wherein the plane along which the objective lens component moves is parallel to the focal plane. 14. The riflescope of claim 1, wherein an image of the target is shifted relative to the aiming mark at least 50 MOA in object space, in response to 1.0 mm of lateral movement of the objective lens component. 15. A method for adjusting the aim of a projectile weapon, using a riflescope mounted on the weapon, the riflescope including a housing, an eyepiece mounted at a first end of the housing and a transparent optical window fixedly mounted at a second end of the housing opposite the first end, the housing supporting an objective lens component having an optic axis, the method comprising: forming a forward-most image with the objective lens component at a forward-most focal plane of the riflescope, the objective lens component (a) having an optic axis, (b) being disposed entirely in front of and distal to the forward-most focal plane, and (c) being slidably supported on the guide track for lateral, non-pivoting movement of the objective lens component relative to the housing along a plane perpendicular to the optic axis; displaying an aiming mark in a field of view of the riflescope; compensating for ballistic elevation or windage by laterally moving the objective lens component relative to the housing in a straight line perpendicular to the optic axis of the objective lens component without tilting the objective lens component relative to the housing, and thereby shifting an image of a distant target relative to the aiming mark; and superimposing the aiming mark on the image of the distant target in the field of view to thereby aim the weapon. 16. The method of claim 15, wherein movement of the objective lens component in the straight line adjusts an elevation setting of the riflescope, and further comprising: laterally moving the objective lens component relative to the housing in a second straight line perpendicular to the straight line and the optic axis without tilting the objective lens component, and thereby adjusting a windage setting of the riflescope. 17. The method of claim 15, wherein the objective lens component includes a primary objective lens component located proximal of an end of the housing opposite an eyepiece of the riflescope, and the riflescope further comprises a secondary objective lens component fixedly mounted within the housing between the primary objective lens component and the eyepiece. 18. The method of claim 15, wherein the image of the distant target is shifted relative to the aiming mark at least 50 MOA in object space, in response to 1.0 mm of lateral movement of the objective lens component. 19. The riflescope of claim 1 wherein the at least one objective lens component comprises an objective lens assembly comprised of at least a second objective lens element and a first objective lens element, the second objective lens element being positioned between the first objective lens element and the eyepiece. 20. The riflescope of claim 19 wherein the first objective lens element and the second objective lens element are mounted in fixed relation to each other, wherein the objective lens assembly is slidably supported on the guide track for lateral, non-pivoting movement. 21. The riflescope of claim 1, wherein the entire objective lens system is driven laterally with the objective lens component.
