Mounted this on my 91/30. I found this to be a good base for my scope. At first I was going to use it for a red dot, as we can only shoot out to 200 yds, but the mount is too high for this. You can not have a cheek weld while using it. I don't think it is the mounts fault It is probably just the type of rifle it is. As with ALL my scopes, I use blue Locktite on all screws for mounts and rings. The screws to level this were very "touchy". a little turn made a huge difference in level. I just took my time leveling it. I have recommended it to my friends that have 91/30's as well. 14 bucks for a rail/mount it is hard to go wrong.
Pros: See title
Cons: Sits too high for a red dot
