What does a muzzle brake do? In short, they help dampen recoil. This is especially true when it relates to large guns. In fact, muzzle brakes can reduce recoil by almost 50 percent.
Shots are louder – Noise increases with a muzzle brake. There is a sonic blast that spreads horizontally when you use a muzzle brake. The gas, as it escapes from the barrel in a side-to-side motion, also causes the sound of the shot to increase. Expect that as you shoot, the sound of firing the bullet will increase.
Muzzle brakes are effective with some models reducing felt recoil by as much as 50 percent. However, muzzle brakes are often the opposites of sound suppressors. They can make the rifle's report sound much louder, especially when fired in enclosed spaces.
Muzzle brakes are designed to reduce felt recoil, which can significantly improve accuracy and speed up follow-up shots. Flash hiders, on the other hand, are designed to reduce the visible signature of the muzzle flash and protect the shooter's vision in low light or night conditions.
