You do not put "gas" in a Desert Eagle...gas operated means the slide is operated via the escaping gas of the catridge that was just fired - forcing the slide back, ejecting the spent round, slide will come forward due to the recoil spring and a new round will be chambered.

The Barrett M82 is a .50 caliber semi-automatic sniper rifle that operates using a short-stroke gas piston system. When a round is fired, gas from the fired cartridge is diverted through a port to cycle the action, ejecting the spent casing and chambering a new round from the magazine. Its modular design allows for easy maintenance and customization, while the heavy barrel enhances accuracy and reduces recoil. The M82 is primarily used for long-range engagements and anti-material purposes due to its powerful caliber.
A pistol which automatically loads the next round into the chamber for firing after the previous round is fired.
