I have cleaned the cosmo from the internals and the surface of the stock. The bore is excellent but had a fair bit of copper fouling.... It's the electro stenciled extra numbers that confuse me...
I could tart up the stock but I prefer it unmolested, once messed with they are never the same.
Set me back the Canadian equivalent of $447 USD.. The Yugo's are the most expensive of all up here, they are thin on the ground.
