Compact and multipurpose: The M4 model with short magazine tube (3 magnum or 4 standard cartridges + 1 in the chamber) and 14” (355 mm), barrel is a compact weapon that has been devised for use in more restricted environments.
Versatile and reliable: The versatility of the m4 shotgun can also be seen in its interchangeable stocks: telescopic, fixed stock or pistol grip stock, in technopolymer reinforced with fibre-glass, replaceable without tools. The choice of tubular magazine is fundamental since it allows the continual reloading of cartridges without having to loosen grip or move from a firing position: the weapon is thus always loaded and ready to fire and there are no breaks in defensive cover. All models have a limited number of parts, which have been assembled in such a way as to allow quick and easy stripping and re-assembly without tools.
