Yes, a muzzle brake can affect accuracy. Muzzle brakes redirect gases that normally exit the muzzle to help reduce recoil. This can change the point of impact for your shots. Some shooter experience increased accuracy with a muzzle brake, while others may find that their groups open up slightly. If you are concerned about accuracy, it is best to test your rifle with and without a muzzle brake to see which configuration works best for you.
