The invention comprises a rifle scope having an adjustment sighting mechanism, the mechanism itself, and methods of making and using the rifle scope and adjustment mechanism. The rifle scope includes an inner and an outer tube, the outer tube mounted on the rifle and the inner tube being sealed within the outer tube. The inner tube is fixed in a ball-type joint at one end, with the other end free and having positioned therein an erector lens or a reticle. An adjustment mechanism adjusts the sight of the rifle scope by displacing the second end of the inner tube. The adjustment mechanism includes a threaded adjustment plunger that is rotationally fixed with respect to the body of the scope. The adjustment plunger threads to a rotating member having a threaded portion. As the rotating member rotates, the adjustment plunger, being prevented from rotating, moves in a direction perpendicular to the axis of rotation of the rotating member. As the threaded adjustment plunger moves inward or outward with respect to the outer tube, it adjusts the position of the inner tube, which is biased against the adjustment plunger by a spring. The rotating member is rotated by a dial, having an engaged position in which rotating the dial moves the adjustment plunger and a disengaged position in which rotating the dial does not move the adjustment plunger. The disengaged position is used to reset the zero on the dial after the rifle is sighted in at a particular distance.
