AK is an assault rifle.
AR-15 is an assault rifle
Brief History for those confused. In world war II, the Germans chopped the 8mm mauser in half (not literally) to to give the 7.92 x 33 Kurtz and chambered a full-auto weapon in that caliber. It was designed to be more powerful than a pistol but less powerful that the regular rifle. It was to be compact like a machine pistol. It was called the Sturmgewehr which is literally German for "assault rifle"
After the war everyone else caught onto the concept of an intermediate, full auto compact rifle--except those in charge at the US military, who insisted on staying with a 30 cal "full power" round. Thus the US forced NATO to use 308 over various intermediate proposals.
Then the US came to its senses, adopted the AR-15--said "sorry our bad" but we are in charge so we decide .223 you you all can suck it.
This happened about 1970 (While the M-16 is synonymous with Vietnam, European troups where equiped with .308 rifles to be good neighbros with outher NATO buds), so there are some 'purists' who insist that the AR-15 or AK-47 being an INTERMEDIATE cartridge is not a "man's gun" and thus prefer the full power of a "Battle Rifle"
We rediscovered this in PRS when everyone stopped shooting 308 and dropped down to 6 mil and about 30 grains of powder for anything inside 100 yards.
Basically the original rounds used in military rifles were WAY overpowered for the ranges at which combat took place.
Battle Rifle: Full Power Centerfire in a military caliber such as 30-06, 308, 303 British, 8MM Mauser, 7.62x54R (This term is used to contrast their how power status as a reaction against 'assault rifles')
Assault Rifle: Intermediate Power, AUTOMATIC, rifle. (unless you are a politician)
Great post.
A couple of technical questions for the history nerds.
Other than the original Armalite AR-15, what other AR-15's in production have a selective fire capable of automatic fire?
Would it be more accurate to state that the M-16 is an assault rifle to differentiate the selective fire differences between the AR-15 with semi-automatic only and the modern M-16's with selective fire capability in the modern lexicon?
The only reason I offer this critique on your post is the modern political trend of claiming AR-15's in wide circulation among the civilian population are assault rifles, when in fact without the full auto capability, I insist that they are not.
Also, as posted elsewhere in the forum, the earliest US Gov publication defining the assault rifle:
