ABSTRACT:
A gun flash hider, formed to include a first expansion chamber, a first flow divider, a plurality of first exhaust passages, an exhaust head, a second expansion chamber, a plurality of second exhaust passages and a second flow divider, whereby high-temperature high-pressure gas produced after firing a bullet undergoes two expansion decompressions and two flow diversion decompressions, through which the gas is sequentially discharged from the first exhaust passages and the second exhaust passages, thereby substantially reducing sonic boom volume, amount of flame and recoil force produced when firing the bullet, and increasing stability and shooting accuracy when using a gun.
