The kickback system!!!
I got interested in guns after I wrote an article about snipers on pdf. The quest to know more about guns lead me to this.
The story began long time back when one fine day in my physics class my teacher taught me that “every action has equal and opposite reaction”, this is what we know as Newton’s 3rd law. It’s an interesting law, which said if I slap somebody then chances of me getting one in return was very high. Scary!
I was also taught that this law has many applications, like the recoiling systems of a gun. Recoil is also called knockback, kickback or simply kick.
So what is kickback system?
If I had to define recoil or the kickback then I’ll define it as the backward momentum* of a gun when the ball is discharged. Now, according to 3rd law of Newton, the recoil caused by the gun will balance the forward momentum of the ball (a projectile). This momentum is transferred to the ground through the body of the shooter if you're holding a gun, while in heavier guns the momentum is transferred to the ground through its mount. The diagram should help you understand this process better.
* Momentum is the quantity of motion of a moving body, calculated as product of mass and velocity of the object.

Now it is very important to understand that in firearms which 're recoil operated, the entire firearm doesn't recoil when the bullet is fired, but only a part of the firearm is allowed to recoil and the rest of the firearm remains motionless, well almost. In case of a recoil operated action has the bolt is locked at the point of firing, ergo it enables the recoil operated action to fire heavier cartridges.
Now there are 3 types of recoiling systems
1) Long recoil: For example automatic shotguns.
2) short recoil: For example automatic machine guns and semiautomatic pistols.
3) Inertia: For example bigger shotguns
1) Short recoil-
When you press the trigger in a gun with short recoil, the slide and barrel which are initially locked together (shown by 2 slots in diagram) move back. While slide moves the entire distance backwards the, barrel moves about half the distance, disengages itself form the slide and tilts down slightly. Simultaneously the bullet is fired and then the slide comes forward, the barrel is put in place a new bullet is put in place for the next shot.
Now if you’re wondering how does the barrel tilt as it moves back, then it’s the interaction of the pin and barrel which causes it. The pin moves down and the slot helps the barrel to tilt. Why this is done so is to maintain safe amount of gas pressure in the chamber while the slide and barrel are locked. A tight gas ensures greater range. But if the slide moves back early then it will reduce the gas pressure in the chamber and reduce the force propelling the bullet out of the barrel.
(pls note the barrel tilt shown in the diagram is intentional to make it more visible to the viewers)
It is interesting to note that in some guns the barrel is slowed down while in others the bolt is accelerated to achieve this effect. As the the slide moves backwards, it compresses a recoil spring. The recoil spring then pushes the bolt forwards after the old cartridge is ejected.
2) Inertial recoil system- Inertia is the tendency of an object at rest to remain at rest, this is the main principle of inertial recoil systems. When a inertial recoil system based gun is fired all of its part move rear-wards except the barrel. The difference in motion between the bolt and the gun compresses a short,very stiff inertia spring between the body bolt and bolt head. As the shot leaves the gun, the spring vigorously re-bounces, this in turn creates enough force to unlock the rotating bolt head, eject the spent shell. The new shell is put in place and the spring pushes the assembly forward, locking the rotating bolt head. This system is adaptable to almost any sort of ammunition. Those who use it swear by it, and heres why:
It has just 3 simple parts, the bolt body, inertia spring and rotating bolt head. This reduces the mass and ergo inertia driven systems are faster (about 5rounds per second). The gas is not channeled into the system unlike short and long recoil system. This also gives an ease of cleaning.
When the rifle is held vertically up…
3) Long recoil systems:
Unlike short recoil systems In the long recoil systems the barrel along with the slide moves thr complete distance, and has a lot of moving parts. There are 2 recoil springs as shown in the diagram the one in the butt is used by the bolt while the barrel uses the spring placed at the bottom. When the trigger is pressed, the hammer comes u, strikes the firing pin, which shoots the bullet. Now as the barrel moves back,at some point it unlocks from the bolt, while the bolt stays back the barrel moves forward ejecting the spent shell.
Thrilling? Isnt it???
Before I wind up this article, let me tell you a short story of a man called Bruno Civolani. This man understood the importance of inertia, and its application in guns but nobody was ready to accept his model. His struggle to find someone who backed his idea continued for 2yrs, when he stumbled upon a moped manufacturing company called Benelli.The benelli system turned very popular because of the speed at which it could fire. Believe it or not until 2012 all inertia-operated firearms either were made by Benelli, or used a design licensed from Benelli. A similar story which reminds me Lamborghini's entry into luxury sports cars.
As Curt Richardson said " Failure is a part of innovation...perhaps the most important part".

@Slav Defence That's my official entry into best writer's competition. But my request is, the article should not be taken in the run for title holders. Thanks!
