The Exhaust Valve for M1911 by KJ Works (Part No. 80) is a crucial replacement component, specifically developed for magazines of Gas Blowback (GBB) M1911 airsoft pistols manufactured by KJ Works.
This valve, located at the top of the magazine, is the component that is struck by the hammer and releases the gas needed to fire the BB and cycle the slide. Replacing a worn, damaged, or leaking exhaust valve is essential to ensure proper gas seal and consistency of each shot. Being an original replacement part (OEM), it ensures perfect compatibility and restoration of the functionalities intended by the manufacturer.

Important Maintenance Note: To preserve the lifespan of the seals (O-rings) of this and other valves, it is recommended to always leave a small amount of gas in the magazine after use. The silicone contained in most Green Gas helps keep the seals lubricated and moist, preventing them from drying out and cracking.
