I gave up on finding a Saiga 308 (for now) and have a Century Arms L1A1 on the way. After a LOT of research, the verdict on accuracy seems to be that they keep 1" groups until 8-10 shots. Then the barrel heats up and it all goes to pot. The suggestion is to "put a better barrel on it". A barrel that isn't affected by the heat.
Any suggestions on where to find a good after-market barrel?
