So I know they're legal, but whats this permit I hear you have to get all about? Or is that just a rumor flying around the internet?
Before I'd turn the M&P 15-22 into a SBR I'd just do the same with a standard AR15 and then use a dedicated .22LR "upper" on it. That way I could just put a short 5.56mm upper on it anytime I wanted. The uppers ain't taxed, just the lowers. You can buy shore barrelled uppers over the counter without paperwork of any sort.
Likewise a silencer can be screwed into several different rifles. I'd want one rated for 5.56mm, not .22LR.
