Remember the oil filter suppressor? Sure we’ve all wanted to try it out for ourselves but who wants to spend all the time and money to do the paper work for a little adapter. TTAG posted about this part on Amazon at around $20 does pretty much what you see in the video below. Is it legal however? Not at all, so I wouldn’t try it. It would be a good idea to get a tax stamp and do the paperwork if you are however. Seriously, do the paperwork and get a stamp.
