Well i obviously know better machinist than you.(trained by the ATF and all legit tho). Ever see that crazy slavic guy on the net?(you tube took him off) he took an AK and converted it to feed upside down and used a trough to feed it, he called it "funnel fed" he said it took him a day to make it. Theoretically a few hundred rounds if you want. down side it was bulky and did often jam, but yet again he had only worked on it for 1 day and cost him under 20 bucks to make. Not sure what country he was from, maybe Ukraine. How many "Mass murders" have you seen where the ppl shot back? I am not saying arm everyone, just the security. In the Ca bar, if the bouncer were armed and the staff, he probably would have killed a lot less. same with school shootings . In Israel, the teachers are armed. Maybe we should rethink the laws where nobody is aloud to have a gun of schools or bars because it only disarms the honest ppl. remember this, The 2 biggest "Mass murderers" in the USA ever didn't use guns at all (9/11 and Ok city). Crazies will Kill, no law will stop them. CA bar shooter case in point, 20 round clips are 100% illegal in CA, do we make them 200% illegal? PPl say"Well he will just get it from another state" . Lets say all the states ban them for argument sake. What is going to stop them from being imported from mexico etc? we have massive tractor trailer loads of drugs being imported daily, why cant they bring in illegal guns too? Laws only hurt the honest ppl, criminals dont care about laws.Both you and I know that anyone with basic science can make a killing device to kill many ppl if they wanted to that doesn't necessarily have to be a firearm. Want to slow down gun crimes? stop letting "violent repeat offenders " out of jail, they are responsible for 90% + of killings in the usa.
