A semiautomatic firearm fires one shot with each pull of the trigger. A fully automatic firearm is a machinegun. When you pull the trigger, the weapon will fire until the trigger is released, or it runs out of ammo. There are forms of full auto firearms that fire a predetermined number of shots with each trigger pull- usually 3. This is known as "burst" fire- but is in the same LEGAL class as fully automatic.

I think you have a marking of R I A- for Rock Island Arsenal. Your Inland has probably been back through the Arsenal for repair or replacement of worn/damaged parts.
On full auto about 850 rounds per minute. However, the M2 was the full auto - the M1 was semi auto only, and the rate of fire was as fast as one could pull the trigger.
The M1 carbine is a semi-automatic rifle meaning that with one pull of the trigger the rifle will fire one bullet. The M2 carbine is a selective fire rifle meaning that there is a switch on the rifle which will select semi-automatic or fully-automatic fire. With fully automatic fire the weapon will continue firing as long as the trigger is pulled until the magazine is empty. This type of rifle is properly classified as an assault weapon. Both rifles share many common parts and barrels will interchange. The main mechanical difference is in the fire control parts. Possession of a certain number of unregistered M2 parts is considered by the BATF to be possession of an unlicensed machine gun and is a felony.
