This page provides information regarding the "922(r)" parts count for a variety of imported weapons.  It is primarily of interest in determining the number of "US" parts required when assembling a legal firearm from an imported parts kit.  There are no parts or products available on this site-- it is strictly for educational purposes.

In some cases this information has been directly provided in documents received from the BATFE; in other cases it is simply a 'best effort' put forth by enthusiasts to fill in the blanks. As with any information on the internet, take the following with a grain of salt-- when it comes to legal matters consult the BATFE directly for clarification.

If you have known "922(r)" parts count information on other models of weapons or if you have a correction to an existing entry or other feedback, please email: info922r@gmail.com

(I hope to have all the US flags link to a page with the suppliers of the particular US made components, but not all are ready just yet!  Last Update: 8/7/2008)

  Minimum number of US manufactured parts to achieve compliance: 6 7 4 6 2 5 4 7 4 7 4 5 5
  = US Made Compliance Parts are available for purchase.       1 Does the forearm and handguard count as one or two towards the total? 2 counted as one piece total?   3 Perforated shroud counts as a hand guard.  5 It is not immediately clear if the BATFE considers the trigger frame of the entire lower trigger housing the 922r part. 4 Forearm and pistol grip are part of the "Frame". Subject to interpretation. Many US parts should be available from the recently introduced Sig 556     5 Pistol grip and Buttstock are combined and count as one.  Conversion to G36 (non-thumbhole style) would be two parts.
