The MM-1 revolver grenade launcher is manufactured in USA by the HawkEngineering Co, and is in use by Special Forces of USA, as well as of severalSouth American and African countries. While MM-1 may look much like upscaled MilkorMGL grenade launcher, most probably the MM-1 traces its ancestry back to the Manville machine projector, a revolver-type 20-shot tear gas gun,developed in USA for police use before the Second World War. The MM-1, whilebeing relatively heavy and quite bulky, can provide devastating firepower, withpractical rate of fire as much as 30 rounds per minute. It may be very useful in ambushes and other fast-pacing close combat scenarios.

MM-1 is a revolver-type weapon, with the heavy cylinder being rotated for eachshot by the clockwork-type spring. Spring is wound manually during the reloading. To reload the cylinder, the rear part of the gun is released androtated sideways to expose the rear of the cylinder, which is connected to the front part of the frame and barrel.
