...an AR-15 variant, showed that the weapon was anything but high-powered...
The MSM calls any rifle larger than a BB gun a “high power” rifle.
Many MSM “reporters” are left wing lunatics fresh from being brainwashed and subsequently programmed in college “Journalism” classes.
You sure that some media talking heads are not ignorant enough to describe a BB gun as high powered?
There is some talk of the rifle being a 22lr variant.
