Benelli Raffaello CrioComfort
Benelli Raffaello CrioComfort is the name of a semi-automatic shotgun. It is manufactured by Italian arms manufacturer Benelli Armi SpA. Design details The shotgun has a relatively small number of component parts, incorporating a simple operating principle. The main features of the mechanism are the turning block bolt locking system and the cartridge feeding system (cut off). These serve to make the Raffaello CrioComfort reliable and practical, easy to strip and maintain. Operation Except for the gas operated M4, all Benelli semi-automatic shotguns operate on the same basic principle of inertial operation, with a fixed barrel, utilizing the kinetic energy of gun recoil. This system requires no outlet for gas or barrel recoil, but operates by means of a spring freely interposed between bolt head and bolt. During firing, due to the recoil of the gun, breech block inertia makes it move about 4 mm forward in relation to the power of the cartridge, compressing the spring. Wh ...

Benelli (firearms)
Benelli Armi SpA is an Italian firearm manufacturer best known for shotguns used by military, law enforcement and civilians, located in Urbino, Marche. Founded in 1967 as an offshoot of the Benelli (motorcycles), Benelli motorcycle factory that sold motorcycles through Montgomery Ward, Benelli produces the Gauge (bore diameter), 12-gauge Benelli M3 used by American SWAT teams. Benelli and Benelli USA have been owned by Beretta, Pietro Beretta SpA since 2000. Products Shotguns Many Benelli shotguns utilize an Recoil operation#Inertia operation, inertia-operated system developed by Bruno Civolani. In 1999, Benelli introduced the Benelli M4 Super 90, a gas operation, gas-operated semi-auto shotgun intended for military and law enforcement. The Benelli Super Black Eagle, used by waterfowl hunting, waterfowlers, was one of the first semi-automatic shotguns capable of firing the 2.75-, 3-, and 3.5-inch shotgun shells. Semi-automatic * 121, 121 SL-80, 121-M1 (12- and 20-gaug ...

Shotgun
A shotgun (also known as a scattergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which usually discharges numerous small pellets (petrology), pellet-like spherical sub-projectiles called shot (pellet), shot, or sometimes a single solid projectile called a shotgun slug, slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double barreled shotgun, double-barreled, or in the form of a combination gun. Like rifles, ...

Inertia
Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law of motion. After some other definitions, Newton states in his first law of motion: The word "perseveres" is a direct translation from Newton's Latin. Other, less forceful terms such as "to continue" or "to remain" are commonly found in modern textbooks. The modern use follows from some changes in Newton's original mechanics (as stated in the ''Principia'') made by Euler, d'Alembert, and other Cartesians. The term inertia comes from the Latin word ''iners'', meaning idle, sluggish. The term inertia may also refer to the resistance of any physical object to a change in its velocity. This includes changes to the object's speed or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight li ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ...

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gun is di ...

Spring (device)
A spring is an elastic object that stores mechanical energy. In everyday use the term often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel, although some non-metallic objects like the bow are also springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produces a ...

Design details The shotgun has a relatively small number of component parts, incorporating a simple operating principle. The main features of the mechanism are the turning block bolt locking system and the cartridge feeding system (cut off). Operation Benelli's range of semi-automatic shotguns operate on the same basic principle of inertial operation, with a fixed barrel, utilizing the kinetic energy of gun recoil. This system requires no outlet for gas or barrel recoil, but operates by means of a spring freely interposed between bolt head and bolt. During firing, due to the recoil of the gun, breech block inertia makes it move about 4 mm forward in relation to the power of the cartridge, compressing the spring. When this is fully compressed, it overcomes breech block inertia, thrusting it to the rear under residual pressure, permitting cartridge case extraction and ...
