open bolt kg9
 

i own an open bolt kg9 which i purchased in 1982 before the atf made interdynamic stop production because it could very easily be made full auto. some freaky gun guy at a gun show told me that if the serial # was over 1000, it was considered contraband. the web told me that there were 2500 made before production stopped. mine has a serial # in the 1700's. does any of you super human gun guy's know anything about this gun???
