Lifetime Warranty

This Nikon scope comes with a limited lifetime manufacturer’s warranty against defects in materials and workmanship.

Patented BDC reticle:

The patented BDC reticle allows hunters to hold “dead-on” at ranges beyond those formerly thought conceivable. The BDC reticle is one of the most notable features of the Nikon Buckmaster 3-9×40 riflescope. It is designed and calibrated to provide fast, simple aiming points for various short distances. The BDC system incorporates a series of small “ballistic circles” to produce an unobstructed view of the target for long range shooting while allowing a normal sight picture for shorter-range shots.

Large exit pupils

The large exit pupil helps to improve low light hunting at dawn or dusk, which is the time when the game is usually moving.

Quick focus eyepiece

The quick focus eyepiece allows the shooter to instantly bring the reticle into sharp focus.

Waterproof, fog proof, shockproof

Just like most modern scopes, the Nikon Buckmaster 3-9×40 riflescope is nitrogen filled and O-ring sealed to make it waterproof and fog proof.

Brightvue™ multicoating

Nikon’s Brightvue anti-reflective system of multicoated lenses offers over 92% anti-reflection capability for the high levels of light transmission and optical clarity essential for dawn-to-dusk big game hunting.

Precise, hand-turn 1/4-MOA click adjustments

The precise hand-turn 1/4-MOA click adjustments get you zeroed-in quicker and maintain your setting even with heavy recoil.

Sunshade adaptable

Optional accessory sunshade removes glare in particularly bright conditions and keeps dust and rain off of the objective lens on rainy days or in dusty surroundings.
