ABSTRACT:
A gun telescope extender is an elongated tube with an unobstructed axial bore of uniform diameter and about six bellows folds between its eye end and its scope end. The scope end of the tube includes outward projecting, integral, pull tabs for removing the extender from the telescopic lens. The eye end of the tube is pre-formed with an oblique and slightly concave rim to fit the eye and seal it from light. The eye end is free of outward flare. The bellows compress evenly, without tilt or undue resistance when in use.
