What is the function of a muzzle brake?

The primary function of a muzzle brake is to reduce recoil and muzzle rise, which enhances the shooter's ability to maintain control during rapid firing or when firing powerful ammunition. When a bullet exits the barrel, it creates a large amount of gas and pressure that pushes the weapon in the opposite direction. A muzzle brake redirects this escaping gas sideways and backward, counteracting the rearward force (recoil) and helping to stabilize the firearm’s position as it fires. By mitigating both recoil and muzzle rise, muzzle brakes allow for quicker follow-up shots, improved accuracy in successive shots, and a more comfortable shooting experience, especially in high-caliber firearms.

While enhancing accuracy might be a secondary benefit due to improved follow-up shot capability, the main and direct purpose of a muzzle brake centers on controlling the recoil and muzzle movement during firing. This makes the option about reducing recoil and muzzle rise the most accurate choice when discussing the primary function of a muzzle brake.
