If you have a stamp for an SBR and the stamp says caliber "9" what does this mean in regards to requirement of the caliber of rifle, as well as requirement of having it set up for any caliber at all?
I am over my AR9 and don't ever shoot it thanks to this new 22lr one that is lightyears more fun and cheaper to shoot, but the AR9 lower is stamped as an SBR. I would prefer run my 22lr setup on this lower, and sell off the AR9 as a pistol package. Am I required to have a "9", not that that is really even a caliber, upper on this gun? Furthermore, are you required to have anything. Couldn't my lower just be stripped entirely and unused...?
