The Benelli CB-M2 is an experimental submachine gun.

History

Originally designed in the 1980s, the Benelli CB-M2 was supposedly invented to use a caseless round. However, due to inefficiency, it brought no sales and the project was shelved.

Design Details

The CB-M2 looked like a regular submachine gun, but had a void behind the magazine well; this was an ejection port for rounds to be pulled out when a jam occured. It is similar to a rimfire weapon, where the hammer strikes the top of the cartridge.

Ammunition

AUPO

Some 9mm AUPO rounds.

A brochure advertizing the CB-M2.

The CB-M2 used an experimental 9mm round, the 9x25mm AUPO. Similar to the ubiquitous 9x19mm Parabellum in ballistics, the 9mm AUPO round was advertized as caseless, but was not exactly so, as the cartridge's "case" was permanently attached to the bullet, and left the barrel together with the bullet when firing.
