The cheat itself dates back to the sniper days.
As far as the "Chicken and Egg" question?
I remember SEEING beavertails, as a safety device, first, in 1993.. But nobody used them because they were ridiculous looking.
But as soon as teams started doing the old Sniper trick, most tournaments made them manditory to prevent cheating in 1994.
So technically, the safety aspect came first, but it was the cheating aspect that is the reason they are used.
Same with Automag reg locks. I remember they were out simply as a safety device, but as soon as people started cheating, tournaments made them required.
Rubber bands though, how can you ban those? Some guns came with them...
