So long as you have the sights lined up, it doesn't matter how the stock fits. Russian rifles are short because they wear a lot of clothes over there.

All you need is for your face to be far enough from the sight that you can line them up. With a scope, which you can't put on a M/N without a lot of expense, you need for it to be within the sight focus distance, which is from 2-4" to keep the scope from biting you.
