Makes no difference at all....how the gun looks is totally irrelevant....they all operate the same way.....its scary looks does not make it any deadlier than any
other semi auto.....several use magazines just like the AR but don't look quite as 'military looking' as the AR....
How it was designed to look was for military training but again irrelevant.....and it looks like it does because they were trying to sell it to the military ...the that weapon
would be fully automatic capable....

An
assault rifle is a
rifle that uses an intermediate cartridge,
has the capacity to switch between semiautomatic/fully automatic fire and a detachable magazine.
the AR sold in stores does not have this capability....but does have a detachable magazine....
Other than having a detachable magazine, an AR15 is no different than any other semi auto rifle...if that is your hangup, ban the magazine or limit its capacity if
it makes you feel better....ammo clips are, in reality, nothing more than smaller capacity magazines and can be changed in 2 or 3 seconds...
Educate yourself....
