If you're going to scope them it's just not a matter of buying mounts and rings. You're going to need a new safety installed as well. The stock military safety doesn't allow for the use of a low mounted scope. Then you're going to need to have the bolt handle turned down to clear the scope. By the way, you haven't mentioned the condition of the bore or whether you've checked the headspace. If the headspace is excessive you're going to need to have the barrel set back by a competent gunsmith. A scope isn't going to help much if the gun can't keep three shots on a pie plate at 100 yards.
Installing a new safety and turning down the bolt is going to cost you $100 (on a good day). A cheap plastic stock is another $100. Drilling and tapping for mounts $40. Low end mounts and rings $40. A cheap scope $100.
Now, what do you have for your nearly $400 investment? A ten to eleven pound chopped up military rifle with a less than sterling two stage trigger pull.
