Legal Automatic

Is it legal to own a semi-automatic assault rifle in Kentucky?
I am thinking about purchasing an Adaptive Combat Rifle (ACR), and live in a pretty small town, but I am looking at this,

Just let me know if it is legal, I think this gun is semi-automatic, Im pretty sure it is. I would also NEED a link to whatever source you may have.
The link you provided states clearly that this weapon is semi-auto.
“Specifications
Action : Semi-Automatic”
Lose the use of the phrase “Assault rifle”…you just want to buy a semi-auto rifle in .223.
Gunbroker among others carries them.
