Gas Blowback Airsoft Guns

About Gas Blowback Airsoft Guns

Gas blowback (GBB) airsoft guns offer one of the most realistic shooting experiences available. Powered by green gas, CO2, or HPA adapter systems, GBB platforms use compressed gas to propel the BB while cycling the slide or bolt, delivering realistic recoil, responsive trigger feel, and authentic weapon operation.

Whether you're looking for a compact gas blowback pistol, a full-size GBB rifle, or a gas-powered shotgun, this collection brings together the best gas-powered airsoft platforms, magazines, parts, and accessories in one place.
