Sheesh! AR-15’s? You’d think they would opt for the full auto M16 or newer small arms...
Heaven knows they’ve ordered enough ammo to go full auto.
Robbery by pen is not enough now it will be @ gunpoint!
It is difficult to tell the difference between an M-16 / M4 and an AR-15 unless you can see the selector switch/safety up close. My guess is that Government employees/LEO's would have the mil-spec versions.
The Honorable Jeff Duncan is a civilian and is probably more familiar with the firearms which are available at his local gun shop, the AR-15. Truthfully, they all qualify as AR-15 variants, some with select fire, others without.
