Before we get into how a flash hider works, it’s important to understand what muzzle rise is and why it’s a problem. Muzzle rise is the tendency of a firearm’s muzzle to climb upwards after firing. This is caused by a combination of recoil and the weight of the firearm itself. The heavier the firearm, the more severe the muzzle rise.
Muzzle rise is problematic because it makes follow-up shots more difficult. The gun has to be brought back down into position before another shot can be taken, and this takes time and effort. A flash hider can help to mitigate this problem by redirecting some of the gases that are produced when a round is fired.
