Re-barreling a Yugo M48 Mauser 7.92x57 in .308

Hi

I'm looking to put a .308 barrel on my Yugo M48. I haven't been able to find any of the barrels specifically produced for this purpose in stock anywhere.

What are my options?

I have found some 1916 Spanish and 1935 Argentinean barrels in .308 or 7.62 NATO in stock. So far, I think the 1893 based Spanish Mauser might work better because it was chambered in 7.92 like my M48? I've been reading that some of the Spanish steel used was soft and could take 7.62 NATO only but not any commercial .308. Or was this for the receiver and other components only?

Are there any other .308 barrels from other manufacturers which would thread in and headspace rather simply? I will be having my professional gunsmith do the install but hope to avoid cutting a barrel and retreading or any major redesign to the receiver or barrel. Or might the issues with the extractor and locking lugs all fitting be too much of an issue here? He said he believes both the 1916 and 1935 are compatible, but this is a niche question and just not sure.

I'd much rather re-barrel this great action in a modern caliber, I know I'll shoot more, than put it in the back of the safe and buy a different bolt action .308

Thank you,

  Your M48 is a large ring Mauser, with a large ring barrel shank, and chambered for 8mm Mauser. You are all over the place with bad information, and if you got it from that gunsmith, you need to find another one. All those Spanish Mausers are small ring, and were chambered in 7mm, and some later converted to 7.62 CETME. The Argentine Mausers were chambered in 7.65.

  I think I can guess, you want a military profile barrel in 7.62 NATO? Look for a Spanish FR-8 barrel, an Israeli 98 Mauser barrel, or Lothar Walther can make you a new one. Whatever you find, it will most likely need machine work on the threads to set the headspacing. Then the sights will have to be clocked, and soldered. This isn't a plug and play job.

  The above info is correct. All I can add is: it's most likely going to come out more cost effective to just buy another rifle.

  Or, maybe, an Ishapore Enfield 2A1?

  just to 'note'...........the m-48 is 'safety breeched', so any 'off the shelf' barrel you find will need some machine work.
