another point to be made is that a lot of these groups can be shrunk considerably by handloading- get a good target recepie and duplicate it as close as you can, see how it shoots , then go up and down the scale from there- i got some nifty 5 round clovers using 180's before i knew any better out of my old norc- using 748 and ww cases, she'd put a 20 round mag into a twonie sized hole at 100 yards , but i'd get 4 inch groups using ivi surplus- just shows what can be done- as far as spare parts go, i know the isrealis disassembled the rifles they didn't use into parts, so there probably is some market there as well as the "spares" market in the u.s., but we can't get access to either of those
