I found out the sks pinned barrel can be installed into the reciever after drilling it out, installing it and pinning it. The gas port has to be plugged and it sounds like it can be done. I want the right size barrel to shoot the larger diameter cheap imported ammo rather than being stuck with the 308 diameter ammo. There's .310" diameter bullets available from midwayusa in different weights for reloading too plus the chinese sks bore is chromed lined thats a plus too. BigBill
