According to the letter these do not require registration for ITAR.
a) Occasional assembly of firearm parts and kits that do not require cutting, drilling, or machining;
b) Firearm repairs involving one-for-one drop-in replacement parts that do not require any cutting, drilling, or machining for installation;
c) Repairs involving replacement parts that do not improve the accuracy, caliber, or other aspects of firearm operation;
d) Hydrographic paint or Cerakote application or bluing treatments for a firearm;
e) Attachment of accessories to a completed firearm without drilling, cutting, or machining—such as attaching a scope, sling, or light to existing mounts or hooks, or attaching a flash suppressor, sound suppressor, muzzle brake, or similar item to a pre- threaded muzzle;
f) Cosmetic additions and alterations (including engraving) that do not improve the accuracy, caliber, or other aspects of firearm operation beyond its original capabilities;
g) Machining new dovetails or drilling and tapping new holes for the installation of sights which do not improve the accuracy or operation of the firearm beyond its original capabilities; and
h) Manual loading or reloading of ammunition of .50 caliber or smaller.
Those involved in these activities are required to register with ITAR:
a) Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;
b) Modifications to a firearm that change round capacity;
c) The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);
d) The systemized production of ammunition, including the automated loading or reloading of ammunition;
e) The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;
f) Rechambering firearms through machining, cutting, or drilling;
g) Chambering, cutting, or threading barrel blanks; and
h) Blueprinting firearms by machining the barrel.
I think we need to setup some kind of deal with a few gunsmiths so we can get these done for us and stay legal.
