Muzzle rise refers to the upward movement of a firearm's muzzle when it is fired. This phenomenon occurs due to the recoil generated by the bullet being discharged. As the bullet exits the barrel, the force pushes the gun backward, causing the muzzle to lift. Muzzle rise can affect accuracy, especially in rapid-fire situations. Shooters often need to compensate for this movement to maintain their aim. Techniques such as proper stance and grip, along with the use of compensators or muzzle brakes, can help reduce muzzle rise and improve shooting performance.
