For those who know much more about guns than I do, couple of questions:

1. When was the tec-9 first made available to the public? (I ask because it was used in the Columbine shooting and I’m sure any lengthy discussion about gun control will raise it as an example of how the old assault weapons ban didn’t work completely)

2. When was the AR-15 first made available to the public? (in addition to the reasoning above, I’ve seen a lot of the “when we were in high school we had rifles on gun racks in our trucks and nobody shot up the school” memes)
