Re: scope it or modify stock?
I think I'd probably chop the stock also and retain iron sights. I bought one years ago from a buddy at work for $100 that was beat to crap and someone had (badly) drilled and tapped it for a scope so that's what it gets. but one day it will get a new barrel and a better scope along with a nice stock. Headspace on mine is right on the verge of being unsafe to shoot. Yours looks to be in better shape than my beat up one.
the mannlicher stock looks great on these though, mine has same length barrel but a cut stock. Great little brush buster of a carbine!
