This sound is commonly labeled as a silenced M4 from Escape from Tarkov, the hardcore shooter released by Battlestate Games in 2017. Short weapon audio clips from Tarkov spread widely through gameplay edits, compilations and meme videos because the game's gun sounds feel detailed and grounded. The suppressed M4 version stays popular because it communicates precision and danger without the oversized boom of a louder rifle. It is often grouped with other FPS reaction sounds such as Boom! Headshot! when creators want a sharper payoff.
