Like others have said, if it a 100% gun in good to like new shape, DONT mess with it, worth more as a military gun than a halfa#s sporter. The aftermarket scope mounts that take place of the rear sight suck also, never hold zero, Ive tried three different brands, they all suck!. Unless you plan on a full custom rifle, which will run 600.00 at the way low end "nothing very impressive" and the sky is the limit on the upper end, I just wouldnt do it!. To start, the rear portion of the receiver needs to be cut down "area for the stripper clip", thats going to run around 60.00 + finishing, next drilling and tapping the receiver, thats around30.00 a hole, reforging or welding ona new bolt handle, 60.00 to 125.00 + more than likely some stock inletting, fitting and installing a safety to clear the scope 50 to 175.00 depending on the style of safety + the cost of the safety plus the cost of the scope bace, rings and scope. For that money, you can go to an auction sight like
www.gunbroker.com and find a rifle set up with a scope and come out way ahead.
