What exactly is involved in getting the ppsh barrel into the AK trunion? I know it will need to be sleeved to match the trunions inner diameter- do I remove metal from the barrel or the sleeve or both? then I need to plug weld the two together before pressing it into the trunion, would a mig be suitable for this?
the other question I wanted to ask was- would the leftover barrel stub from a cut Ak barrel be a good choice for a sleeve? or would the crome lining inside cause issues with borring it out to the right diameter?
