AR-15 Savant
I would prefer, it has a similar look. But it's design has some important differences; it is Semi-Automatic only, and doesn't have full automatic fire or a three round burst function. These are important differences. I'm not going to give the left any leverage.
The fella in the video was not wrong. The military adopted the Colt/Armalite AR15. They simply changed the name when it was adopted. The AR15 was a machinegun or a semi auto.
The AR15 can be a Title 1 Semi Auto, or Title 2 Select Fire.
