M4 Battle Brown 14" + DOOR-BREACHER
State of art
Description
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.

Technologies
Benelli’s gas operating mechanism is famed for its reliability, strength and safety and guarantees accurate shooting over the years – as approved by the Marines. Simplicity, sturdiness, original and ingenious design are the distinguishing features of the patented A.R.G.O. Auto Regulating Gas Operated system, the gas-operated mechanism at the heart of the MR1 and M4 models.
A.R.G.O. guarantees firing precision, reliability, durability and confirms the technological superiority of Benelli.
Consisting of a gas operation unitcontaining a short-stroke piston, A.R.G.O. is located under the barrel,near the firing chamber, in order to exploit the hotter gasses andgreater pressure. The gasses flowing from the barrel expand (in thegas collection cylinder) and rapidly accelerate the piston stroke,which simultaneously impacts with the bolt follower pins transmittingsufficient thrust to the bolt to send it backwards. It is self-cleaningbecause the position of the gas operation unit means that it works with gasses that are still hot and with relatively high pressures;in this way, the operation will always be safe with less build upof deposits. It is self-regulating because the gas operation valve actsas a regulator that expels excess gasses during firing.The greaterthe volume of gas flowing from the barrel, the quicker the pin valveopens and allows it to escape, in this way reducing the pressureinside the gas operation unitSelf-cleaning and self-regulating, A.R.G.O. guarantees firing precision, reliability, durability and confirms the technological superiority of Benelli.
