Horton 4×32 Mult-A-Range Lighted Reticle Scope features a lighted reticle for low-light shooting.

Magnification: Also called power and indicated by the symbol “x”. A 4x riflescope makes the target appear four times closer than when seen with the unaided eye. Choose high power for varmint shooting, medium power for big game at moderate ranges, and low power for precise, close range shooting at fast targets.

Eye Relief: The distance behind the eyeguard at which you can see a full-sight picture. Bausch & Lomb and Bushnell riflescopes give you an extra margin of comfort and safety with extended eye relief and soft neoprene eyepiece guards.

Field of View: The width of the sight picture at 100 yards. A wider field of view makes it easier to spot game and track moving targets.

Image Sharpness and Brightness: Our distortion-free optics give you a bright, super-sharp sight picture.

Parallax: A condition that occurs when the image of the target is not focused precisely on the reticle plane. Parallax is visible as an apparent movement between the reticle and the target when the shooter moves his head or, in extreme cases, an out-of-focus image. Our centerfire riflescopes under 11 power are factory-set parallax free at 100 yards: rimfire scopes at 50 yards. Scopes of 11x or more have a special range focus to adjust for parallax.

Exit Pupil: The diameter of the shaft of light exiting the scope toward the eye. It is used to rate the brightness of a riflescope’s sight picture. For example, a 4x scope with a 40mm objective lens (the front lens) has an exit pupil of 10mm, a very good rating. The larger the exit pupil, the easier it is to keep the eye aligned with the sight picture, and the better the scope will be in low light.

Rugged Body Construction: Our manufacturers uses a high-durability aluminum alloy formed into a one-piece tube. Each riflescope is rustproof, virtually scratch-proof and a beautiful complement to your most expensive rifles.

Sealed, Waterproof and Fogproof: All 1″ diameter Bausch & Lomb/Bushnell riflescopes are not only nitrogen purged to remove any vestige of internal moisture, they are O-ring sealed to prevent the entry of external dust or moisture. Your riflescope remains crystal clear in all types of weather.

Multi-X® Reticle: A riflescope feature that gives you a clearly visible aiming point. Even when hard-to-see game blends into the background or the light is poor. The fine-line crosshair center section covers a minimum of the target. The heavier outside section leads your eye directly to the center intersection. The result is fast precision aiming.

Coated Optics: Many rifle scopes optical glass surfaces are coated by magnesium fluoride to reduce light loss and glare due to reflection. All Bausch & Lomb riflescopes are multicoated to further enhance viewing and reduce eye strain. All Trophy riflescopes have a special image enhancing amber, high contrast coating.

Holosight: The revolutionary Bushnell HOLOsight gun sight gives you instant target acquisition through the holographic, heads-up targeting system from U.S. fighter jets.
