Benelli M2 extension tube

[SDBlaster]

Are there any 922r compliance issues in putting an extention tube on a benelli m2 tactical with a pistol grip? Do i have to use an American part or will a benelli tube be ok? Also, anyone have any good recomendations for a light/ mount option?
Thank you,

You have to have 10 or less foreign made parts. A Benelli M2 has 13/14 foreign made parts in stock form, I'm guessing you need to replace the entire mag tube and follower, plus one more part to make it 922r compliant

(c ) For purposes of this section, the term imported parts are:

(1) Frames, receivers, receiver castings, forgings or stampings
(2) Barrels
(3) Barrel extensions
(4) Mounting blocks (trunions)
(5) Muzzle attachments
(6) Bolts
(7) Bolt carriers
(8) Operating rods
(9) Gas pistons
(10) Trigger housings
(11) Triggers
(12) Hammers
(13) Sears
(14) Disconnectors
(15) Buttstocks
(16) Pistol grips (I guess if you are running a M2 in tactical pistol grip format)
(17) Forearms, handguards
(18) Magazine bodies
(19) Followers
(20) Floorplates

Thanks! Any advice on which of these replacement parts is most cost effective/ easiest/ and/ or that will not have an effect on the reliability of the m2?
