The present invention provides an erector system characterized by centered erector lenses and lens holder movement capability to alter relative erector lens placement. Alignment of the erector lens optical centers facilitates the reduction of the phenomenon of trackout. Alteration of relative erector lens position permits a pistol scope or another device embodying the erector system to operate at more than one magnification.

Binoculars capable of simultaneous individual focus and simultaneous individual focus mechanisms therefor are discussed. The binoculars of the present invention are preferably offset hinged in the bridging portion to accommodate various users and for compactness. In addition, the binoculars of the present invention simulate the ease of center focus and combat parallax that results from misalignment of the optical axis and the mechanical axis of each binocular tube.

A variable optical power telescopic sight with adjustable focus control includes a tubular housing having a longitudinal axis, an interior and exterior, and first and second ends. The housing holds an eyepiece positioned at the second end and an erector positioned in the interior of the housing medially of the first end and the eyepiece. To enable side focus control in the telescopic sight, an objective lens system includes a stationary portion positioned in the interior of the housing near the first end and a movable portion positioned in the interior of the housing between the stationary portion and the erector for movement generally along the longitudinal axis to adjust the focus of the telescopic sight. A manually adjustable focus control device projects outwardly from the exterior of the housing in a direction transverse to the longitudinal axis and is connected to the movable portion of the objective lens system. The side mounted focus control device allows a marksman to change the position of the movable portion of the objective lens along the longitudinal axis to adjust the focus of the telescopic sight.

A method of producing a rifle scope having a body made in part of composite material. The method utilizes a composite material tubular housing element, having a rear and having an outer diameter and a metal eyepiece adapter in form of a tube having an inner diameter matching the outer diameter. In the method, the metal eyepiece adapter is adhered partially over the rear of the tubular housing element.
