Pros - Open circle aiming points make target acquisition easy - Designed with .22 Long Rifle rounds in mind - Hand-turn windage and elevation adjustments Cons - Large eyepiece could interfere with bolt action rifles - No parallax adjustment possible - Fuzzy sight picture beyond 75 yards

This scope has a smaller-than-average objective lens, measuring just 32mm in diameter. It’s 11.5 inches long overall, and weighs just over a pound. That’s not too much extra weight for your rifle, but I have seen lighter scopes.

If your .22 is fairly lightweight, you might want to take notice of the eye relief on the P-Rimfire. It’s only 3.8 inches, which is usually plenty, but unusually light firearms might have a bit too much recoil and send the eyepiece into your head.

The glass features a healthy-sized exit pupil of 4.6mm to 16mm.

How Powerful Is The P-Rimfire?

Magnification isn’t as big a deal with .22 LR rounds as it is with more powerful ammunition, but you still want to be able to zoom in a bit. The total magnification on the P-Rimefire ranges from 2X to 7X. Crispness, clarity, and contrast are great across all magnifications, but the image does tend to get blurry and fuzzy beyond 75 yards or so. This is due more to the 50 yard parallax setting than anything else, however. Unfortunately, Nikon has not provided any means to adjust the parallax on this scope.

How Is The Optics Quality On The Riflescope?

The optics on this model are fully multicoated, maximizing light transmission. Image quality is very good, giving you a sight picture that’s almost HD quality.

For this scope, Nikon has used its BDC 150 reticle, which offers several range compensation markers that are designed specifically for .22 LR ammunition trajectory. The scope is compatible with Nikon’s Spot On Ballistic Match Technology.

What’s The Light Gathering Capability Like On The Scope?

This scope’s transmittance is about average, primarily because of the smaller 32mm objective lens. The fully multicoated optics allow the scope to make the most of the available light, and it does perform fairly well in low-light conditions. I just wish the reticle was illuminated.

How Wide Is The Field Of View?

You’ll see a fairly generous field of view with this scope, ranging from 6.4 feet to 22.3 feet at 50 yards. That’s plenty of space to acquire your target, even if it’s on the move.

How Easy Is The Scope To Mount?

Mounting your scope is quick and painless with the P-Rimfire scope, but you will probably need a set of medium or higher rings. Low-profile rings simply won’t work with this scope, because of the large eyepiece. Unfortunately, you don’t get rings with your purchase, so be sure to order a pair when you are buying your scope.

Any Tricks Or Tips About Mounting The Scope?

There aren’t any tips or tricks necessary for mounting the P-Rimfire, other than making sure you have enough clearance between the eyepiece and barrel.

How Easy Is The Nikon P-Rimfire 2–7x32mm BDC 150 Riflescope To Sight In?

Once mounted, it’s time to move on to sighting in your scope. With the P-Rimfire, Nikon has made that as easy as possible, with hand-turn controls that adjust the windage and elevation by 1/4 MOA per click. The turrets have spring-loaded zero reset functions, allowing field adjustments to be made with ease in the bush or at the range.

Even though .22 LR ammunition is fairly cheap, you should start off sighting in using a laser bore-sighting tool. There’s no point in wasting time or brass on this.

How Durable Is The Scope?

This scope is both waterproof and fogproof, since the optics chamber is nitrogen-purged and the lenses are sealed with O-rings. The scope is also rugged enough to be fairly shock-resistant, and it’s covered with a limited lifetime warranty.
