The Century Yugo rifles are pretty good. I'm no fan of Century, but they got the Yugos right. Or they subcontract them out to somebody decent. Either way, they are good to go. The barrels are not chrome lined, but neither are the actual Yugo military issued AKM's. I still prefer a chrome lined barrel in my fighting rifles, but it's not a big deal if you don't shoot corrosive ammo in it.
The Century Tantals are hit and miss. The early ones had a lot of problems. The more recent onces are a little better. My Tantals are early TGI built ones and used excellent quality parts kits. When built right, the Tantal is an excellent AK variant.
I don't think I'll ever be 100% comfortable with corrosive ammo. That said, I do shoot a lot of it. The last batch I got came out to $134 per 1080 rounds including shipping, so it makes a lot of sense for training. My strategy is to have a dedicated training AK in 5.45 caliber, and only shoot corrosive ammo through that rifle. I still clean it well after every range session, but it keeps most of my wear and all risk of corrosion isolated to one rifle. Something to consider.
I'd be a better listener if you stopped talking about stupid crap that doesn't matter.
