The Nikon PROSTAFF 5 4.5-18x40 outfitted with the Nikoplex reticle is beneficial in a variety of hunting situations and can be used with Nikon Spot On Ballistic Match Technology to take the guesswork out of compensating for bullet drop. With enough power for the longest-range shots, the PROSTAFF 5 4.5-18x40 will keep you on target even when shooting through thick brush and timber. This is one scope you can truly count on in any situation. In addition all PROSTAFF 5 riflescopes are built with fully multicoated optics for maximum light transmission, even in extreme low light environments.

Features include:

Nikoplex Reticle 
A perfect choice for shooters wishing to have a clear field of view with a more traditional crosshair, the Nikoplex reticle allows shooters to utilize all that Nikon’s Spot On Ballistic Match Technology has to offer while maintaining one distinct aiming point on their reticle.

Generous, Consistent Eye Relief 
Keeps your brow safe—even with the heaviest recoiling cartridges, lightweight rifles, and severe shooting angles. Long eye relief, also known as high-eyepoint design, provides a clear field of view for everyone, even when wearing eye protection.

Fully Multicoated Optical System 
Multiple layers of anti-reflective compounds on every glass surface provide bright and vivid sight pictures and optimum light transmission and maximum brightness from dawn to dusk.

Hand-turn 1/4 MOA Adjustments 
Reticle adjustments are made in 1/4 MOA click-stop moves you can both feel and hear, and with no backlash to make your shot creep off target. Positive click reticle adjustments get you zeroed in quicker and maintain your setting—even with repeated recoil and under rugged conditions.

Spring-Loaded Instant Zero-Reset Turrets 
To simplify field adjustments, Nikon has integrated this feature into all new PROSTAFF 5 riflescopes. Just sight-in as usual, then lift the spring-loaded adjustment knob, rotate to your “zero”, and reengage. Field adjustments are now as simple as dialing-in your subsequent ranges

Spot On Ballistic Match Technology 
Custom precision at your fingertips 
The PROSTAFF 5 series, like all of Nikon’s riflescopes, are optimized for use with Nikon Spot On Ballistic Match Technology. Spot On allows you to discover all of the exact aiming points on your scope’s reticle at various yardages for your specific ammunition and load.

Quick Focus Eyepiece 
Allows the shooter to instantly bring the reticle into sharp focus.

Waterproof/Fogproof/Shockproof 
Nitrogen filled and O-ring sealed for confidence under the toughest of conditions.
