(Deep Rising) - M1-L1 Triple-Pulse Rifle

An "M1-L1 triple-pulse rifle" lying on the floor of an elevator in Deep Rising.

The M1-L1 triple-pulse assault rifle was a fictional automatic weapon used by a crew of pirates led by Hanover (Wes Studi) in the movie Deep Rising. It had a rotating cluster of 5 barrels and was described by Hanover as being water-tight, air-cooled, and feeding from a 1,000-round magazine (impossible in real life). The weapons' caliber is never stated, but during one scene where the guns are fired by the pirates, 5.56x45mm brass is shown dropping at their feet. It was also described as being manufactured in the People's Republic of China (the crates containing the weapons were adorned with Mandarin characters).

In reality, the prop M1-L1 rifles were built upon Calico M955A submachine guns, and the rotating barrels on the weapons were not functional (they were fitted around the real barrel of the Calico, and were rigged to spin when the trigger was pulled, hence giving the illusion that the weapon fired through them).
