@Corprin no you cant swap a barrel on most AKs without a press. But like @anotero said once its fine tuned it doesnt get touched again.
As far as cleaning, i had to clean my Colt AR15 every 3 outings or itd have failures at the range. That coupled w cost of shooting .223 and it being the only in that caliber, it had to go. Sold on gunbroker within 20min, funds earmarked for the latest m92 pistol.
And yes, i dont clean my guns or airguns until functionality or precision suffers, but as said ar15 forced my to clean it every 3rd outing. Maybe it was the cheap russian ammo i was shooting, dunno. But now my arsenal has been limited to 22lr, 9, 40 and 7.62x39. I reload my pistol rounds, but rimfire and 7.62.
