Okay, have a question: the Armalite (Eagle Arms) AR-180B made 20 years ago had a non-chrome lined barrel and was 1:9 twist. I had one and sold it for those two reasons. Do you guys know of any gun-wizards who could put a chrome lined 1:7 twist barrel on it? Even a Melonited 1:7 twist barrel? It would have to be someone like Marvin Pitts or similar who work wonders.

Yeah, sourcing the barrel would be tough, and likely would be easier to have one made and then Melonited, although chrome lined would be my preference. Wonder if the Brownell's BRN-180 barrel could be made to work?
