Questions & Answers
On the Nikon Pro-Staff 5, 4.5-18x40, SF Riflescope #16367, what does the SF stand for in front of riflescope? Explain first focal point & second focal Featured Answer

SF stands for side focus. The knob on the side of the scope is a parallax setting. If your target is close to you, by adjusting the parallax down, the image will become a sharp clear image. Then to look at a target far away, it would be blurry so you would have to adjust the parallax up until the image becomes clear. As far as First Focal Plane (FFP) and Second Focal Plane (SFP) go. SFP is traditionally your base model scope. When adjusting the magnification/power ring the image/target gets bigger while the reticle/crosshairs stay the same size. With FFP, these tend to be higher end scopes. These differ because when adjusting the magnification ring, not only does the image increase in size, but the reticle also does too. As some of would say “it grows with the target”. I know it’s a lot to take in but I hope it helps and answers your questions.

Will this fit on a Ruger M77 MKII with #4 front and #5 rear rings? It is listed at a 50.3mm outside obj. diameter. Expert Answer

The general rule is that 40mm objective lenses can use medium rings and 50mm objective lens can use high rings. So for an M77 receiver where the front is taller than the rear I would recommend a medium front #4 and a high rear #5 ring.

Bright and clear optics, solid clicks in the turrets, tough enough to hold up to big caliber recoil are all the basics of a great scope, and the Nikon delivers. Then, add features like tall turrets included in the box 1/8 MOA click stops, sunshade in...

Awesome scope at a great price by JWest, Verified Owner, June 9, 2017
I took the opportunity to look through one of these before I bought it from Optics Planet at an unbeatable price. First off I chose the mil-dot reticle model and given that the turrets are listed as 1/8th MOA I was a little disappointed to read that ...

Nice scope by Eric Blanton, March 12, 2016
I will start off by saying that the only thing I didn't like is that optics planet nor the manufacture knows that this scope comes with optional tall turrets and a sun shade in the box. these items only come with the x18 (and 18x custom model) and n...

Outstanding Optics by Non-Typical, May 19, 2016
The clarity of this scope is outstanding. I haven't tested it past 500 yards, but up to 500 it is very bright and clear. The Spot On app works great. I zeroed at 200 yards and was hitting targets at 300 and 500 yards using the BDC reticle. I did ...
