(1) Frames, receivers, receiver castings, forgings or stampings
yes: upper reciever
(2) Barrels
yes
(3) Barrel extensions
yes
(4) Mounting blocks (trunions)
no. don't think this applies barrel mounts directly to upper although I could be missing something here.
(5) Muzzle attachments
no, unless using ria aftermarket compensator.
(6) Bolts
yes
(7) Bolt carriers
yes
(8) Operating rods
yes, should be the cocking handle
(9) Gas pistons
yes
(10) Trigger housings
yes, lower receiver
(11) Triggers
yes
(12) Hammers
yes
(13) Sears
no
(14) Disconnectors
yes
(15) Buttstocks
yes
(16) Pistol grips
no
(17) Forearms, handguards
yes, has both parts listed in manual as separate items.
(18) Magazine bodies
yes
(19) Followers
yes
(20) Floorplates
yes
In stock configuration I would guess 16 foreign parts.
I have no way to confirm this as 100% reliable but seems like a good start. I just looking at this in the assumption that changing parts by a owner of the foreign firearm is a violation of 922r.
what can be changed?
(1) Frames, receivers, receiver castings, forgings or stampings
(2) Barrels
(3) Barrel extensions
(5) Muzzle attachments
(6) Bolts
(7) Bolt carriers
-1 (8) Operating rods
yes, new charging handle made in usa
(9) Gas pistons
(10) Trigger housings
-1(11) Triggers
yes
-1(12) Hammers
yes
-1(14) Disconnectors
yes
-1(15) Buttstocks and (16) Pistol grips
yes, changing stock thumbhole stock to ar type with pistol grip will remove 1 foreign part.
-1(17) Forearms, handguards
yes
(18) Magazine bodies
(19) Followers
-1(20) Floorplates
yes and no, extended floorplates but I would not use this option for parts count do to cost and accidentally installing factor mag.
It would look like changing these parts would be the way to go now and are available made in usa.
charging handle
trigger
hammer
disconnector
stock and pistol grip
forearm and handguard or mag floorplates
another good option would be the gas piston but not aware of any being produced. this would allow the use of any 2 out of three, stock hand guard, stock mag floorplates or ria compensator.
