A lot of new to Vepr 12 owners ask about 922r.
It's about foreign parts count, and specific parts are named to be counted.
This was posted by Sharky a while back in a discussion:
Although it seems backwards, you should never go by a count of the US parts. Based on 922r the BATF will not count US parts, only the number of imported parts. Look at the list of 922r countable parts and count how many foreign parts from the list are on your rifle. If 10 or less you are good to go no matter how many US parts are on on it.
