Default Gas Operated

I'm probably going to sound like a complete idiot here by asking this, but I'm still learning about guns and how they operate. What does it mean that a rifle is "gas operated" such as an AK-47 for example?

As each bullet travels through the AK barrel, a portion of the gases expanding behind it is diverted into the gas tube above the barrel, where it impacts the gas piston. The piston, in turn, is driven backward, pushing the bolt carrier, which causes the bolt to move backwards, ejecting the spent round, and chambering a new round when the recoil spring pushes it backfire, automatically cycling fresh rounds into the chamber, until the magazine is exhausted or pressure is released from the trigger.

All gas operated rifles like the AK and AR have a gas port in the barrel that directs gasses back to cycle the action, either by way of a piston (AK) or the direct impingement method (AR15).

M-1 Garands and M14's (M1-A) have the piston below the barrel. This is one of the semi-automatic types of mechanisms. Other types include recoil operated and blow-back. Gun mechanicals are unbelievably interesting and can be exceedingly complex, depending on how far into it you want to delve. I am a "gun-nut" and find the subject fascinating.

There are some great books out there. Do a search on Amazon and see what pops up.
