I am think about install a one piece 7 shot US made mag tube on my M4, but worried about 922r compliant.
I have been reading about this and seems teher are 2 answers, someone claims Benelli has already had enough US made parts on the M4 so as long the extended mag tube is US made, I am fine.
But others saying that I have to get other 5 more US made parts(mag follower, triggers, gas piston etc.) to make it 922r compliant, or I have to register it as a short barrel shotgun.
Please forgive me if you think I am paranoid or this question has been asked before, I have googled and read a lot about this but I am still confused about this.
I came from AK world so I think I am pretty clear about the rules of 922r when dealing with AK, but not so sure about Semi shotguns.
Thanks
