No, all Armalite rifles had an AR designation. Even this dumb thing:

Look I don't make the rules, ar means assault rifle now and if you knew your history you'd know the ar 15 is the fifteenth one

Relatedly, the G36 and the AK-47 are also assault rifles and never classified as "AR" because Armalite doesn't make them. And the HK-416? It's literally just an AR-15 with a different brand name.

AK stands for Assault Rifle in Russian. The G means "Gruesome" as in what happens when you are Assaulted with a Rifle

It's not, though? Armalite didn't make 15 models or rifles and the model 15 was based on the model 10. More importantly, most of the AR series were not even assault rifles. The AR-5 was basically a bolt action pistol.

"If you know your history" is an odd thing to say in this context.

That rifle you listed sure like like you could mount an assault with it. It's what the AR-1? The first assault rifle? And the 1 also means only one bullet goes in the magazine. AR-15s have 15 bullet magazines. Keep up mate

Are you doing a bit?

No I would never lie on the internet
