Benelli Raffaello CrioComfort is the name of a semi-automatic
shotgun
A shotgun (also known as a scattergun, peppergun, 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 discharges numerous small ...
. It is manufactured by Italian arms manufacturer
Benelli Armi SpA
Benelli Armi S.p.A. is an Italian firearm manufacturer located in Urbino, Marche, Italy. Founded in 1967 as an offshoot of the Benelli (motorcycles), Benelli motorcycle factory that sold motorcycles through Montgomery Ward, Benelli and Benelli US ...

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
inertia
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newto ...
l operation, with a fixed barrel, utilizing the
kinetic energy
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion.
In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2.Resnick, Rober ...

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, for according to Newton's third law the force requ ...
.
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 reloading with the conventional system.
The pressure of the spring is calculated to delay the opening of the action, which occurs after the shot has left the barrel, and to regulate the different pressures produced by cartridges of varying power, with no need for braking.
