Nikon Prostaff 4-12×40 BDC Review with Detail Features

Nikon ProStaff 4-12 x 40 Black Matte Riflescope (BDC)

Patented BDC Reticle

This is the patented reticle from Nikon that lets you focus on even the most distant targets. You can find instructions on the best shooting range numbers for your BDC reticle from the Nikon website. Different rifles have different shooting settings. What makes this a unique feature and a favorite of any Nikon Prostaff 4-12×40 BDC review is that the see-through ballistic circles help you handle long range shooting while still presenting normal range images for closer shots. This is a feature that will train any hunter about accurate shooting aim. It is lightweight and is 14.1 inches long.

Great Magnification and Multicoated Optical System

Whether it is a bright sunny day, a foggy morning or late in the evening, the Nikon Prostaff 4-12×40 BDC offers great picture thanks to high resolution imaging. When doing some long range shooting, you need a riflescope that can offer versatile magnification. It zooms from 4-12x on a 40mm lens which makes shooting as far as 600 yards possible. This is the perfect riflescope for long range shooting rather than short range targets. When it comes to the multicoated optical system, it offers 98% light transmission which means that even the poorest visibility conditions are helped by this light boost.

Quick Focus Eyepiece

The great thing noted in any Nikon Prostaff 4-12×40 BDC review is that this is a product that can be used on any type of rifle. This means that some rifles pack more power than others. It is for this reason that this Nikon riflescope offers a quick focus eyepiece with 3.7 inch eye relief. This keeps you from straining your eye and protects it from any recoil effect. For those sunny days, you can get a sunshade option. In addition, the nitrogen-filled, O-ring sealed housing makes it perfect for use in any conditions because it is waterproof, fogproof and shockproof.

Easy to Use Controls

The Nikon Prostaff 4-12×40 BDC has a smooth selector ring. This means you can quickly zoom in and out while you use your rifle. In addition, the precise hand-turn 1/4-MOA click adjustments enables quick and simple field adjustments while on the hinting range, and it is protected by a seal cap to avoid the hand-turn from being spoilt. These 2 features are key especially when making split-decisions during hunting. You need quick and easy to use knobs and hand-turn adjustments that do not interrupt your shot. In fact, you can maintain or adjust your settings even during recoil.

Unique Design and Perfect Finish

Nikon is known to have some of the best photography and recording equipment in the market today, and the Nikon Prostaff 4-12×40 BDC is no exception. What makes it a favorite among hunters is the black matte finish which gives it a smooth and professional looking finish that looks good on top of any rifle. This riflescope is also lightweight at 15 ounces and is only 12.4 inches long. The precise hand-turn, as mentioned, is protected by a cap and the casing ensures the product is not only waterproof but also dustproof and shockproof, which means it is resistant to damage.

  1. I have hunted a wide varity of game and using different guns and scopes. I love the way this scope focuses and the clearity. I may have abused the scope but when the reticle started moving Nikon stood by their warranty and went out of their way to please me. Their customer service and repair are outstanding. Having a great Scope and support, can’t be beat!!!!!!!!!!!

  2. I have a gun shop and carry Leopold, zeiss and nikon.
