Tell that to my friend/neighbor who had a 'faux' can confiscated 3 weeks ago for being 'too lifelike' on his M&P 15-22....according to the Feds who accosted him if it doesn't have a certificate of legalization, it isn't....ergo my question whether proper documentation to prevent this kind of thing will be availableThe MFI M4 Style Fake Suppressor does NOT reduce muzzle noise or muzzle flash in any way. So these are 100% legal for the regular civilian to own in all 50 US States. No FFL needed, No Special License, No Permit Required & No Special Tax Stamp needed to order. Therefore, no documentation is needed.
Well, you are certainly entitled to your opinion on the matter. I would say, however, that it is unlikely that you have seen EVERY possible configuration of the MP5, since some military hardware doesn't make it into the public arena.
