For my next firearm purchase I'm hoping to get something automatic. I know it has to have been registered as a machine gun prior to May 19, 1986. I'm not really sure whats available though, since I'm only really familiar with handguns. I like the look of the FN P90 but I don't know if they were around before the cutoff date. I also like the Glock 18 but I'm aware that these are impossible to obtain. I'm not too fond of the AK. I also like HK firearms and I've heard that for around $10,000 I could buy a sear that was registered before the ban and put it into any HK 9x series to convert it to a automatic version of that weapon. I'm not sure if thats what I want to do yet or not though. What civilian legal automatic firearm would you recommend and why? How much should I expect to spend? Thanks in advance for any advice.
