It already has a light recoil, but a muzzle brake will provide two primary benefits with each shot:
1. Reduced recoil
2. Reduced muzzle rise
As everyone knows, the explosion of the gun powder in the cartridge produces expanding gasses that propel the bullet through the barrel and out the muzzle. Under original muzzle configuration, those gasses continue straight out in the same line as the bullet creating an opposite force: recoil.
That recoil, due to how the firearm is held and positioned, tends to result in muzzle rise as well. That muzzle rise must be corrected before firing the next round. Because the muzzle brake directs gasses to the sides and up, the recoil and resulting muzzle rise are both reduced allowing for greater speed and accuracy with proper training.
The one downside is the sound of the shot is also redirected to the sides and up. That means the experience is less pleasant for those who might be next to you at the range. And proper hearing protection is absolutely essential — even though that is always the case.
