It's not like a spot welder is terribly expensive or difficult to get your hands on. That said, I've never bothered to try and build an AK from an 80% receiver

It's not like a spot welder is terribly expensive or difficult to get your hands on. That said, I've never bothered to try and build an AK from an 80% receiver. It always looked like a hassle, and frankly the AKs that I own just sit in the back of the safe anyway. I've built a handful of 80% ARs though, pretty simple. But nothing is as simple as the 80% Glock pistols. Those are literally ten minutes with a Dremel once you've done a couple, if you don't care about it looking a bit scruffy.
