a few years back a bunch of us got together and bought AK parts kits for $79 each. These were live guns that had had the receiver de-milled. We got new receivers and other 922r compliance parts and built them ourselves for about $180. Probably not as pretty as yours, but a fun thing to do.

into Canada I figure. How close do they check, really?
