APEX Gun Parts carries the pieces needed to meet the 922(R) US Compliance parts count.

In order to legally build a parts kit, no more than 10 imported parts may remain in the completed firearm. This is generally done by replacing foreign-made parts with domestically-built parts.
Imported parts that get counted are as follows:
(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
(17) Forearms, handguards
(18) Magazine bodies
(19) Followers
(20) Floorplates

This effort to stock/list 922(R) US Compliance parts is now getting underway.
