Questions & Answers
what does EFR stand for, on this scope ?

Hi,
Extended Focus Range(EFR) - Adjustable Objective Lens Dials Out Parallax from 10m to Inifinity.
Thank You.

What accessories do I need to mount it on a Savage B17 FV? Thanks!!!

The Savage Arms B17 FV comes with Weaver mounts on the receiver. You need to grab some compatible rings (mid or high rings) so the bolt will clear the reticle when cocking the bolt. Low rings will hit the reticle, I think 11mm is the minimum rise required to not hit the scope. That should be all that is needed to mount and set your zero with the new glass!!! Good luck.

Helpful Positive Review Great scope by Greybeard, Verified Owner, June 2, 2017
This scope is the best rimfire scope I have ever owned. The optics are very clear and very bright and I really like the reticle design. Being able to dial the parallax adjustment to as close as 10 yards greatly enhances the clarity which is necessary...

Product Info for Nikon ProStaff Target EFR 3-9x40 Rifle Scope

Nikon ProStaff 3-9x40mm target EFR Rifle Scope 6734 is a fast-targeting, high accuracy rifle scope that gives you the versatility of a variable zoom rifle scope with the fast-focusing capabilities of a short range sight. These professional-grade rifle scopes by Nikon are equipped with a fast-focus eyepiece that helps bring their Precision reticles in full focus almost as soon as you align your eye with the scope. Equipped with fully multi-coated optics, these Nikon Rifle Scopes offer high brightness images from dawn to dusk, thanks to their high light transmission rate, which will make hunting all the easier. The Nikon Pro-Staff 3-9x target EFR Precision Scope has been specifically engineered for .22 LR and air rifle ammunition, but it can be used well with any type of ammunition using the Spot On Ballistic Match technology integrated in the scope. Nikon Sport Optics has constructed these ProStaff rifle scopes with zero-reset turrets, which take all the guess work out of making windage and elevation adjustments by tailoring the Nikon ProStaff 3-9x40mm Zero-Reset Rifle Scope to your weapon and load out.image

Speaking of adjustments, the Nikon 3-9x40 target EFR Variable Zoom Rifle Scope is equipped with windage and elevation knobs with a 1/4 MOA adjustment rate, so you can precisely tailor each shot to your specific situation. Nitrogen-filled and O-ring sealed, just like the other products in the Nikon Pro-Staff line, the target EFR is completely waterproof and fogproof, enabling you to take it into the wettest, most demanding hunting grounds. With a wide variable magnification range, fast-focusing capabilities, and quick return-to-zero adjustment capability, the Nikon Pro Staff target EFR Quick Focus Rifle Scope is a versatile and powerful rifle scope every hunter would be proud to own.
