Oh I TOTALLY get the SBR thing! Dude - 7.62x39 is the KING of SBR rounds! (sensibly cheap readily available rounds, anyway...) Still - as you point out: Suppressors, SBR's, FA.... While all useful, let's be honest; The fun factor at the moment FAR outweighs any "usefulness" of those things since the S has not hit the F. And I question the usefulness of FA if you do not have a tank.... Wanna kill these ads? We can help!
