I can't help you on the Pine Ridge scope because I don't have any experience with it. I would question its ability to handle the recoil of that gun frankly.

I also have a Mossberg 835 with the ported barrel, ported Star-dot choke and limbsaver recoil pad. Before the ported choke and better recoil pad that gun would absolutely stomp you shooting the 3.5", 2.25 oz Nitro company triplex loads that I use. With double porting and that pad the gun now is very shootable, more of a big push instead of a sharp kick. When I switched to the hevishot loads and tightened the pattern I scoped the gun because I was afraid I would miss at close range.

I put the Bushnell Trophy 4 X 1.75 scope on it go get through my first season with the gun because it was relatively inexpensive and I liked the circle X reticle. I planned to put a better scope on it later, one that I was confident would hold up to the recoil. After three seasons, 9 turkeys and some range work it is still on the gun and has performed flawlessly.

Pros and Cons of scopes

Pros
1. More accurate aiming (necessitated for me by super tight patterns)
2. Magnification of the image (useful as long as you don't underestimate the range).
3. Ability to range the bird using the Circle X reticle
4. No batteries to replace, no electronics to fail. doesn't require turning on.
5. With good mounts I am unconcerned about it getting knocked off zero with proper care
6. Ability to more easily get the point of aim on the center of the pattern than fixed sights

Cons
1. Even though my scope wears the Butler Creek scope covers, the exterior lenses can get wet due to breath or rain
2. Potential for the zero to get knocked off due to internal scope failure of damage from accidental "mishaps" like dropping it on pavement, etc.
3. Potential to misjudge range with a magnified image. I look at the bird without the scope until I'm ready to fire in order to avoid this
