Hi there, and thanks for stopping off to read my review of the Nikon Prostaff Rimfire II 3–9x40mm BDC Riflescope. Rimfire calibers are still quite popular rounds, since they are fun to shoot and extremely accurate. To get the most out of your rimfire rifle, you need a good scope. Nikon’s Prostaff Rimfire II lineup is advertised as offering the quality you need at a price you can afford. Does the scope meet up with those claims? That’s what we’re about to find out.

How Big And Heavy Is The Scope?

The Prostaff Rimfire II features a large 40mm objective lens, but the scope itself is fairly compact and lightweight. It measures 12.3 inches in overall length, and weighs just 13.1 ounces.

The scope’s eye relief is somewhat short, at 3.6 inches, but that shouldn’t be too much of a problem with most rimfire applications.

A 13.33mm exit pupil allows for wonderful light transmission and magnification.

How Powerful Is The Prostaff Rimfire II?

With magnification from 3X to 9X, this glass offers great performance. Crispness, clarity, and contrast are all fantastic throughout the entire zoom range, allowing you to get up close and personal with a target that looks like it’s almost HD quality. The power selector spins smoothly, while still offering enough resistance to prevent you from accidentally changing it.

How Good Are The Optics On The Riflescope?

Nikon has fully multicoated the optics on this glass, maximizing light transmission and image quality. The eyebox is a bit short, but the focus is fast and sharp no matter what you’re aiming at.

The reticle on this model is the BDC 150 variant, offering several range compensation markers to you. Those range compensation markers are open circles, allowing you to still see even the smallest target when you’re taking aim. Unfortunately, the reticle is wire instead of etched glass, and is not illuminated.

How Well Does The Scope Gather Light?

Nikon advertises this scope as having transmittance of 98 percent, which is three points higher than I’ve typically heard as being the theoretical maximum. Curious. Whatever the case may be, this scope’s 40mm objective lens and fully multicoated optics transmit light like nobody’s business, giving you a bright image even in low-light conditions. Once again, I just wish the reticle was illuminated.

How Wide Is The Field Of View?

The Prostaff Rimfire II does provide you with a good field of view, ranging from 4.4 feet to 33.8 feet at 100 yards.

How Easy Is The Prostaff Rimfire II To Mount?

Mounting your scope shouldn’t cause you too many problems, since this scope is easy to mount. You’ll just need to make sure you have the right set of scope rings to do the job, as they aren’t included in the box.

Any Tricks Or Tips About Mounting The Scope?

Nothing special to report here, folks. Let’s move on to sighting it in.

How Easy Is The Nikon Prostaff Rimfire II 3–9x40mm BDC Riflescope To Sight In?

When you begin sighting in your scope, you should start off the process with a laser bore-sighting tool, saving yourself time and ammunition. Then, head out to the rifle range and start laying down patterns to fine-tune your windage and elevation adjustments. This model has a maximum adjustment range of 80 MOA for both windage and elevation, with 1/2-MOA clicks. The hand-turn controls are easy to use, and integrated zero-reset features make field adjustments easy.

How Durable Is It?

For weather protection, Nikon has nitrogen-purged the optics chamber and sealed the lenses with O-rings. This makes the whole setup both waterproof and fogproof, and it’s also shock-resistant. If anything does go wrong with the Prostaff Rimfire II, it’s not only covered by Nikon’s limited lifetime warranty, but also its No-Fault Repair/Replacement Policy.
