A 12.5" 5.56 carbine gas AR can work well with a .065" gas port. That allows you to step up and down with buffer masses suited to that use.
Also remember that ALL NATO 5.56 ammunition is NOT equal at all. You can end up with a very wide variance, depending on ammo selection. Much of the import ammo is lacking in at least a few areas.
Are you saying a 6920 barrel could be cut down to 12.5 and run well if suppressed? Or what would you consider the perfect length barrel to cut a 6920 WITHOUT modifying the port.
