Agree with everything I've read so far.
Lever-guns, to me are simply the best tool for many jobs. I think we had it right in America when it came to that, while the Europeans were all about bolt-actions. I am VERY fond of bolt-actions, but to be practical about it, short of poking at a woodchuck or coyote at 300 or 400 yards, a lever makes more sense for everything I'd need to do. I have no nostalgic motivation and never watched the western movies which made them so popular.
My eyesight... (fill in here half of what others have said) is not improving.
(EDIT): I'd much PREFER receiver sights - a peep with a square-topped front post, and while I've used them, I do not like scopes on levers because they really seem to take away from the sleekness and handiness - become more clumsy to me. They'll work and will help me see what the gun can do, but it just contradicts so much of the handling properties of a lever.
That the dot-sights have become SO compact, seem more reliable and have much better battery life, they make a lot of sense. Less weight, less bulk, fewer snaggy thingies... I'm no opposed to them on levers at all. I LOVE this "shake-awake" on the Sig Romeo 5.
To maybe seem a bit hypocritical, I'd not put one on a Remington Rolling block - it's not something I'd grab for the kinds of things a lever excels at. While utility is the key attraction to me, regarding levers, some of the over-the-top tacticrap that's been put on a few "tactical levers," to me is ridiculous. I'd take the wood over the unfriendly plastic any day and not for the sake of aesthetics or historical accuracy. Wooden stocks feel better and are more comfortable to me, and in some cases lighter than the "plastic" stuff, whatever it may be made of. Profuse protrusions - knobs, levers, wheels, dials are all dangerous (or at least highly annoying) snag-potential. Picatinny rail all over everything is like wrapping a shovel handle with gravel-embedded tape and if you need a light, a laser, dot-sight, 4-16x scope with night-vision capability, "co-witness" sights, you probably need different gun and a couple more guys with guns.
