Abstract: A rifle sighting system, that includes a metal base assembly and a train of optical elements affixed to the base assembly, and including a front optical element having a front surface and having a rear optical element having a rear surface. A cover, made of light weight material is affixed to the base assembly and sized and shaped to cover and protect the train of optical elements, other than the front surface of the front optical element and the rear surface of the rear optical element.

Abstract: A combined reflex/telescopic sight that includes a telescopic optical element train and a view window, offset from the optical element train. A transition assembly is positioned to receive light from the optical element train and the view window and has an image display, a collimating lens-set positioned to transmit light to the image display and a luminous reticle. This assembly may be placed in a first mode wherein light from the optical train travels through the collimating lenses to the image display and light from the view window is blocked. In a second mode light from the optical train is blocked and light from the luminous reticle travels through the collimating lens set and is combined with light from the view window and a resulting combined image appears at the image display. Finally an actuation assembly is adapted to permit a user to switch the transition assembly between modes.

Abstract: A scope having a zoom mechanism that includes a cam tube holding an optical train of lenses whose relative positions change when said cam tube is rotated, causing an image seen through the scope to expand or contract. A gear is in contact to said cam tube and is positioned so as to rotate said cam tube when said gear is rotated. Finally, an actuator is positioned on a side of said scope and operatively connected to said gear so that said actuator causes said gear to turn when a user moves said actuator.

Abstract: Certain embodiments described herein comprise a scope for mounting on a firearm to provide a sight. This scope is adjustable in at least one of elevation and windage. The scope comprises a main tube, imaging optics in the main tube, a movable optic assembly that holds at least a portion of the optics; and an adjustable mechanism configured to adjust the position of the movable optics assembly. The adjustment mechanism comprises a rotatable adjustment knob, an adjustment screw, and a biasing element that biases the adjustment screw with respect to the adjustment knob. In an engagement position the adjustment knob drivingly engages with the adjustment screw such that rotation of the knob causes rotation of the adjustment screw, and in a depressed position the knob disengages the adjustment screw.
