I've built two of these types of cetme/g3's. You're going the right way by tacking it up with a cetme steel mag in place. For the other places get a 30 ga copper sheet and mold it around your bolt carrier. Move it along as you tak things in. No sticky BCG.

The receiver flat is chromoly so it's a bit more rust resistant than regular steel. I do hit the inside with cerakote where I can. But really the bolt carrier is so honking big and has so many points of contact I slather it in moly grease.

I'm partial to this scope and it's dirt cheap on Amazon often. CamelCamelCamel.com it to see when it's on sale.

Heavy sucker but very bright from the large lenses.
