AGT has the Vulcan 3 30cal as standard, unchoked 700mm barrel - which I have. I heard the 22 cal version is a chocked polygonal barrel. I've also been hearing that AGT was using a standard barrel initially than switched over to polygonal with the 25? For example, I contacted Tony at Talon, He says the 25 cal 700mm barrel, while at Krale, they list the same gun with a polygonal barrel. Anyone know for sure what AGT is currently doing here, again, this is for a 25 cal 700mm barrel, and is it choked or unchoked? thanks AGN!
