I got a 30-40 Krag that I need some help with. I think I have a cut down rifle in a carbine stock that someone sporterized years ago. I looked at a few serial # tracking sites and it should fall into rifles made in 1898. The stock looks real and not a rifle stock cut down. The upper handguard is missing and rear sight is gone and replaced with a Marbles leaf semi buckhorn Its a good shooter for being 120 years old Can anyone enlighten me on this rifle? I'd like to get at least reproduction sight and handguard to make it look the part. I'm not sure if its worth it though. If the rear sight is a no go, can someone point me in the direction of a scope mount that the receiver was drilled for. I full well understand that this is not a collectors item.
