The M4 is capable of automatic fire, the AR 15 is not
When Armalite first developed the rifle, they gave it the nomenclature of AR-15. When they sold the rights to Colt, Colt continued using the AR-15 name, and applied it to all variants of the rifle (usually accompanied by a model number). M16 is a military nomenclature - the rifles are still AR-15 rifles, but built to certain specifications, as required by military and law enforcement customers.
The AR-15 uses a direct impingement operating system, whereas the Mini 14 uses a gas piston system based on the M14 rifle.
Armalite rifle. Donβt listen to that idiot who said autolite rifle
About .05, obviously.
A sporter air rifle and what?
AR-15 = Semi-Auto civilian rifle M4 = Select Fire Military rifle
There is no difference.
A carbine is a type of rifle.
The Colt AR-15 is a sporter rifle
The nature of this question makes it difficult to determine what you are asking, so I'm going to throw a few answers at you to hopefully answer it. AR in the firearms world is the initialism of ArmaLite, the company that employed the inventor of the AR-15 design, Eugene Stoner. Technically one could call any firearm built by the Armalite company an AR. However, the AR-15 and its derivatives are extremely common firearms and the design has been copied by many companies. Rifles built in the pattern of the AR-15 (and the earlier AR-10) are often referred to as "AR's" as a catchall term for that design family.
