Does anyone know if there are any MG34 barrels out there for sale, in 7.62x51 (Win .308), that would work on the semi-auto models that Marstar sells??

Gee, I guess I'll have to make friends with someone over there...
I wonder is a modern MG3 barrel in 7.62 could be modified.....
Well, the MG34 barrel is just a threaded barrel. There is notheing special about it aside from the annular rings turned into the muzzle to help shew off carbon deposits.
If you have a sacrificial 8mm barrel, you can (with a barrel vise) thread off the cam-lock and then copy the original barrel's threads from a suitable 7.62 blank, lathe in the annular rings, and re-install your cam-lock section. Indexing won't be an issue since there is no sights.
The biggest expense will be getting a gunsmith to machine the blank and chamber the barrel, assuming you don't have a suitably sized lathe and the skill to use it yourself.
The greater challenge will be tweaking the feed system to make it run properly. You need a modifiedfeed plate:
Portugal also made these in 7.62, though I have never seen one in person - but it CAN be done. The gun itself is strong enough, it's just barrel and feed mechanism swaps & tweaks.

No, an MG34 barrel is longer than an MG42 barrel.
Just use a 1919 7.62 barrel if you need chrome lined.
I'm told that the 7.62 Sportco barrels work very well in MG34s....
