5. Looks of Machine Guns Gas fed systems work from gas left from the shell after the gun was fired. The M-16 is an example of the gas fed system. Recoil system powers the gun from the recoil pushing on the bolt. Most earlier machine guns used the recoil system. Blowback system works just like the recoil system except the gun housing moves instead of the bolt. The Tommy gun uses the Blowback system.
