A "Semi-Automatic Ejector" is a firearm mechanism that uses a combination of a firing pin, spring, and gas pressure to automatically extract and eject spent casings from the chamber after each shot. It operates efficiently, swiftly removing the fired cartridge and preparing the firearm for the next round. The 🔫💥🔽 symbolizes the action of the semi-automatic ejector, with the gun firing (🔫), the explosion (💥), and the downward motion (🔽) representing the ejection of the spent casing.
