Don't let anyone dissuade you from "scoping" a lever gun if you need it, I've done several, mostly using "home-built" mounting systems that, while looking unorthodox (usually because they are old "collector" vintage rifles that I don't want to mess with "originality" in any way),they work.
The one thing that you might not think of when scoping a lever gun is that, because of the low angle of the tang/butt stock to the top of the receiver. once you get a scope mounted, your sight line will be considerably higher than the original iron sights. Your cheek position/weld will be considerably higher on the butt stock...not an insurmountable problem but it will affect your shooting accuracy if you don't adjust to the fact that you can't "really snuggle up to" your butt stock like before.
The change in "posturing" is identical too long range shooting with a vernier tang sight if you have ever done any of that, the higher your vernier gets, the higher your cheek is on the butt stock....long range vernier shooters have been proving that it can be done.
The last 1/2 dozen lever guns I scoped this past winter (with Red Dots) all have cheek risers built for them for this reason...not compulsory, just makes it easier...
