The ocular lens on all CATSEYE rifle scopes was made with a larger diameter than most rifle scopes, helping to create a generous 4" to 5" eye relief and a larger exit pupil allowing your eye to receive a greater amount of light. This greatly reduces eye strain and fatigue making this one of the most comfortable scopes to look through. Camera quality glass was used to give you a clear and undistorted image. All lenses were fully multi-coated to provide the brightest possible view without glare or reflections. The NEW CATSEYE Scopes have an integrated slanted "hood" on the objective, functioning as a built in sun shade. All CATSEYE are also water, fog and shockproof. The CATSEYE Windage and Elevation turrets are featuring an advanced PUSH / PULL, ZERO RESET system with an Allen screw

Keep your target clear, in sight, and on line even in limited light conditions with the BSA 3.5-10X50 Catseye Rifle Scope. The BSA Catseye was created to help hunters target game better when it becomes hard to see, and the scope delivers on this front. Featuring an interchangeable red, green, or blue etched and illuminated reticle, the ocular lens was additionally constructed with a larger diameter than most scopes. This creates a longer four-to-five-inch eye relief and a larger exit pupil that allows your eye to receive a greater amount of light, greatly reducing eye strain and fatigue.

Camera quality glass provides a clear and undistorted image at any magnifications, and all lenses are fully multi-coated to provide the brightest possible view without glare or reflections. Water-, fog-, and shock-proof, these scopes are "fast focus" and have standard four-inch eye relief. The magnification ring has clear, engraved markings in gold, and the engraved objective and ocular dust covers have an easy-to-grip handle for quick and simple removal. The scope comes with a limited lifetime manufacturer's warranty.
