Yep 5.45 would be my preference too. I'd be on that thing like white on rice on a paper plate in a snow storm.
I'm betting vaporware on some of the stuff we are supposed to get. Like the mk107, ak12, that rpk, the list grows with every year. I'm to the point where I'm done buying everything except accessories and ammo to shoot with. If something cool pops up ill jump otherwise I got or had one and don't need another.
