I have three, 1) A Marlin Glenfield that I purchased in the 80's It has a X4 scope on top of see through mounts and I put a leather sling on it.
2) Henry Big boy, blued steel, 44 Mag with Holoson red dot, I know - looks a little odd, but its pretty effective at 75 yards. I haven't tried it any further so the jury is still out on that. I did add a leather sling, but it slid around on my shoulder terribly. Ive replaced it with one called "the claw". If y'all haven't tried one of these slings - you should , I highly recommend it.
3) Henry Big boy with the brass receiver chambered in .357. I removed the buck-horn sights. I have difficulty seeing the iron sights. Its an age thing. Old enough to afford the rifle, too old to see well enough to use it. Let me know if anyone else can relate to that.
I added a peep-sight just above the receiver. I purchase it from a company called Skinner Sights. I selected their brass option. Looks good on top of the brass receiver. Initially it appears to be a game changer for me - but honestly, I haven't had it at the range yet. The rifle is just too nice. That brass shines like a new penny and I cant bear the thought of scratching it. I never was going to use it in the woods, just as plinking rifle. One that is more affordable to shoot than the .44 .
I was going to trade it, but my grandson has already laid claims to it. I'm a big fan of the lever action rifles, and now - I guess he is too.
