Yeah the 30 Carbine round is this weird in between round that's hotter than pistol ammo but anemic compared to rifle rounds . When it was invented it was a nearly perfect caliber PDW platform. I just wish some company would offer any type of carbine or pistol in the 30 Carbine caliber now so that the ammo companies would start producing more ammo at cheaper prices.I like the carbine a lot more than the AR. And I've used one for more than 40yrs. But I have to admit, the carbine won't out shoot an AR platform
The M1C will never be as user friendly or ergonomic as an AR. But neither is an AK and for whatever reason I dig ...no I LOVE both rifles a lot more than ARs. Color me old uncool and a non operator.
