Arent you a reloader? If not that's a route you could go to saving your rifle. Slug and the barrel and select bullets of the proper (oversized) diameter. I don't reload 8mm but it's a .323 bullet. I have an M1917 I had to get stratgic with, it wouldn't shoot .308 168 FJMBT so I slugged it and its .3105 so it's close enough but I had to chase a bullet for it and right now I'm using a 180(?)gr bullet flat battom.
This rifle wouldn't group worth a **** with -.06 surplus or my reloads that I was using in my Garand. But once I altered my tactics and started loading for this one rifle and IT's needs, it groups much better.

never stick anything in the gas tube or the gas key...it's all "self-cleaning".

The pic was taken right from the box when I got it back from Springfield Custom Shop

How about Hamburger Hill?

It's a very angry 1.5

Not nearly as many made and even fewer were imported. The charginf handle mimics the AK, the handguard is longer for the entire gas tube, and the magazine is shaped a bit differently. They're typically is well worn good condition. I had one, nice rifle, like any other SKS it just has a novelty about it due to the numbers manuf/imported.
