on ar15.com there are 7.62x25 gas guns people have made.
Sabre Defence Industries sells a 9mm SMG-variant of the XR-15. Not much more pricey than their high quality XR-15A4 Subcarbine (in which I'm a happy owner). This is considering, though, if you're willing to spend up to three grand (tax and shipping included).I was wondering if this was possible or if anyone has tried to adapt a Gas Op system to a 9mm AR?.
Sabre Defence makes some immaculate rifles, primarily their prestige is in the barrel. My XR subcarbine has a stainless steel barrel w/ chrome-vanadium bore, much greater quality than any of the barrels our issue C7s/C8s and US issue M16s/M4s have.
