Submachine gun competition

Submachine gun and belt-fed machine gun shooting competitions take place across the United States every month in many states where firearms which fall under the National Firearms Act are legal. Although submachine gun competitions have been happening in the United States of America since the early 1980s, it is one of the least-known shooting disciplines due to the restricted nature of the firearms involved. 
To the novice submachine gun competitor, the average match would have many of the same elements as an IDPA or IPSC event with the only difference being the firearm used and the amounts of ammunition carried. Usually competitors move through a stage, navigating the course of fire (COF) and shooting the various target types while being timed. 
A competitor in a typical subgun match may use anywhere from 300 to 800 rounds of ammunition depending on the number of targets, the shooter's skill, and the stage design. Some sub gun events incorporate other firearms into the matches such as pistol and shotgun. 
Some of the firearms used are the Heckler & Koch MP5, Uzi and Mini Uzi, Colt 9mm SMG, Sterling, Mac-10, Sten, Thompson, Carl Gustav M/45 / Swedish K, Reising, and the MP40, as well as many others.
