Nikon Prostaff 3-9x40 Matte Nikoplex Riflescope


Be the first to review this product

The scope's optical system transmits up to 98 percent of available light, ensuring maximum brightness from dawn to dusk.

To simplify field adjustments, Nikon also integrated a zero-reset turret into the riflescope. Just sight in as usual, lift the spring-loaded adjustment knob, rotate to your "zero," and re-engage.

Field adjustments are now as simple as dialing in your subsequent ranges.

Nothing boosts a shooter's level of confidence better than generous, constant eye relief, which is why Nikon provided 3.6 inches of eye relief in the ProStaff. No more rough kickback from heavy recoiling cartridges, lightweight rifles, severe shooting angles, and just plain excitement. Other features include a Nikoplex reticle; a nitrogen-filled, O-ring-sealed housing that's waterproof and fogproof; support for an optional sunshade accessory for bright, rainy, or dusty conditions; and a quick-focus eyepiece.

Multicoated optical system: Multicoated lenses boost light transmission up to 98%—unheard of in similarly priced scopes.

Generous, consistent eye relief: Keeps your brow safe—even with the heaviest recoiling cartridges, lightweight rifles, and severe shooting angles.

Precise hand-turn 1/4-MOA click adjustments: Positive-click reticle adjustments get you zeroed in quicker and maintain your setting even with heavy recoil.

Sun Shade Adaptable: 40 mm & 50 mm models.


Extremely bright sight picture: Allows for high-resolution images even when hunting in the least desirable conditions.

Versatile magnification range: Offers the flexibility needed for any type of hunting situation, from heavy timber to the open prairies.

Waterproof, fogproof, shockproof: Nitrogen filled and O-ring sealed.
