How a Gun Works..?

Question

Ok now I get how a basic gun works w/ the pistons firing it off, and the force from the bullet winding the bolt back and all of that. But how do bigger/mounted guns work? Like anything bigger than a .50 Cal (I'll just use the 50 as an example).

I know that the trigger lets the bolt loose, it pulls the bullet down through the Chambering Ramp, the forward force makes the piston slide forward and hits the bullets primer; shooting the bullet forward. Then the force from the bullet brings back the bolt and the whole process restarts. So I understand the actual firing. But;

-How does the bullet get to the Cartridge Guide?
-How does the shell get out of the gun? (You always see them coming out onto the ground, what makes them come out of the gun)
-And what exactly does the Operating Rod do? I cant really see a point but it probably has a major role

So three questions; 10 points for 3 answers. Thanks for your time.

Probably not

The world must be coming to an end...........A LIBERAL that owns a firearm? What we they do next.

You can use the web, can't you (questioner)?

Answer 2

The caliber .50 machine gun, M2 is recoil operated. Recoil operation means that the bolt is locked to the barrel extension when the cartridge is fired. This assembly of bolt and barrel recoil back 5/8ths of an inch. Two little arms called lock depressors push the lock block down. The bolt recoils the rest of the way back. The fired casing is ejected downward by the new cartridge which shings down into the T-slot on the face of the bolt.

As the bolt travels reward, the cartridge extractor pulls a fresh cartridge out of the belt. The reward travel also causes the feed pawl to pull the belt in for the next cartridge. Both the cartridge extractor and the feed pawl arm work off of cam slots cut in the bolt.

As the bolt travels forward, it picks up the barrel, and the lock block moves up to lock the bolt and barrel assembly together. Just before the bolt moves into battery, the trigger bar trips the sear, which releases the striker, firing the cartridge. Exactly how far out of battery the sear is tripped is called the "timing".

The M2 machine gun does not fire from open bolt like M60, the M240B or the M249 SAW. The bolt is in the closed position when the trigger is pulled. To fire it semiautomatically, the bolt catch must be released by a sleeve on the buffer assembly. The bolt catch will hold the bolt after firing a round, and must be pressed to allow the bolt to go forward. Pressing the butterfly trigger will fire the weapon.

Answer 3

Go to the library ,get a copy of Small Arms Of the World .
Different weapons work by various systems .

Answer 4

There are many different mechanical engineering designs for firearms. This is a good website to illustrate some of these systems. http://science.howstuffworks.com/gun-roundup.htm
