Hey Leif, I've been looking at these too. I think in addition to the stock you need to buy the bolt handle conversion kit to change it from the straight bolt handle to the bent for the monty carlo stock. If you want to put optics on it I think it is a Must! Look at the pic on the web sight you'll see what I'm talking about. Cut, file, drill, tap and die. Or I bet Bert aka BPTactical could do it for you.
