I broke out the Saiga 7.62x39 tonight and did some serious scrubbing. Not that an AK needs it, but it's the principle of the thing. The Saiga is a gun that doesn't get nearly enough range time with me, but it's a well put together weapon once you "de-sporterize" it.
When I have a question about anything AK related, the guy I go to is TheAK47nut.
I've known this guy personally since we were literally still on the playground, and AK's aren't just his hobby, they are his passion. His to-the-point, no nonsense Youtube Channel has good info, and I don't mind giving him a little promo. Swing over there and subscribe to his channel.
