Muzzle brakes for reducing recoil forces from firing firearms may include a body extending longitudinally from a proximal end to a distal end. A bore may extend through the body from the proximal end to the distal end. The body may include a vented portion proximate the proximal end, the vented portion including at least one opening providing airflow communication between the bore and an exterior of the body. The opening may be oriented to direct vented gasses in a direction other than parallel to a longitudinal axis of the body. An unvented portion may be located proximate the distal end, the unvented portion free of any openings oriented to direct vented gasses in a direction other than parallel to a longitudinal axis of the body. A diameter of the bore in the vented portion may be greater than a diameter of the bore in the unvented portion.
