Hey everyone back at it again. I was digging around and found an old yugo sks receiver and a barreled action stub. I remembered i bought em a long time ago but lost interest. I started stripping the barrel of its goodies. Nothing i did worked on unscrewing the bloody thing even a pipe wrench. So i plan on getting a barrel from copes. My old barrel is a chinese one but im pretty sure the Fsb and stuff will fit with a dremels help. I know the new barrels have no wrench marks, no gas port, and no extractor cut. Can anyone help me out with info on these. The wrench marks are no problem just would like to know because one will need cutting for the recoil plate.
