"fully semi-automatic" select fire
The urban dictionary folks need some help with understanding of how weapons work and their terminology.
There is no such thing as "fully semi-automatic". It is either Semi-automatic, which means one squeeze of trigger and one round is fired, OR it is "Full automatic" which means one squeeze of trigger and howeve many rounds per minute can come flying out without having to depres the trigger again....
So it is either semi-automatic, or FULL automatic.
I love it when people who know nothing about gun basics start offering up renditions to show how ignorant they really are..
