I'm in the process of picking out two uppers. Doing my research and trying to decide what I want. If you were going to get a 7.62x39 upper would you get a 16 1/2" or 18" barrel? My way of thinking is it won't make much difference but I don't exactly know.
Also what length of barrel would you choose if you were getting a 6mm ARC upper? From what researched that's part of that cartridges claim to fame. Supposedly it doesn't matter, it'll perform well with just about any length of barrel. I plan on getting a suppressor at some point so I probably need to keep that in mind while choosing.
