I'd love a 6mm arc barrel. And people can say what they want but they've been producing the shit out of these virtus guns. Whoever could produce a barrel for 6mm arc or even 6.5g along with cold hammer-forged chrome-lined say Noveske barrels. Or even proof carbon fiber. Take my money. I bet you that's easily a couple million in sales per year. Mostly because you'd be the only one doing it. Otte from in led we trust has been doing the MPX Barrel so I don't think it would be any type of legal issues.
