I thought it was a fully automatic weapon but now people are saying semi - auto weapons are assault weapons. Which is it?!?!? Maybe if people could agree on an operational definition we could more properly debate the topic?!?!?!?!?!?! https://www.cnbc.com/2018/02/21/def...sault-weapon-is-a-very-contentious-issue.html “AR-15-style rifles are NOT ‘assault weapons’ or ‘assault rifles,’ according to NSSF’s website. “An assault rifle is fully automatic — a machine gun. Automatic firearms have been severely restricted from civilian ownership since 1934.” States also tend to have different definitions in gun laws for what is an assault weapon or assault rifle, and it often changes when lawmakers seek to close what they perceive as loopholes.
