Illustration of forces in muzzle rise. Projectile and propellant gases act on barrel along barrel centerline A. Forces are resisted by shooter contact with gun at grips and stock B.

Forces A and B operating over moment arm / height C create torque or moment D, which rotates the firearm's muzzle up as ...
