I really don't think I would go through the trouble or expense but I was wondering about something like that after you guys replied. How about if you had the 10-15+ grand, legally purchase a registered full auto AK 47 or receiver only if one could be found. Would it then be possible or permissible to do a little conversion?. Does the ATF ever allow caliber changes with or without their nominal fees on a registered receiver?
Way, way too much trouble.
