Does anyone know if any of the big ring yogos had small ring threads like the turkish models. Also I am having trouble romoving the original barrel does anyone have any ideas before I have to get out the lathe and boring bar.
Some of those are tight, but I haven't heard that any require drastic measures. If the condition of the original barrel is of no concern, you can use a relief cut to make removal easier. Do note that unlike the standard 98 Mauser, the M48 has a cut in the barrel for the extractor, so the replacement barrel has to be properly aligned, not just torqued up on the inner receiver collar like the 98.
