Abstract
A firearm with muzzle noise reducer is disclosed with one or more barrels in which the bullets reach their final velocity in front of the barrel and a muzzle noise reducer constructed such that it can divert propellant gas upon reaching the final bullet velocity. This construction for diverting the propellant generally is in form of openings located length-wise in a barrel. The openings may have different forms and arrangements, e.g. an electronic and/or inertia-activated time-control element that controls the divergence of propellent gas. A method of reducing the muzzle noise is also disclosed.
