Abstract: A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16) with a cartridge case (26) therein and countermass main body (18) movable in opposite directions. Gas from a deflagrating propellant moves the movable members and applies directionally opposite forces upon the breech end surface (40) and the stand pressure surface (32), which results in the force cancellation and ensures that the barrel (12) remains stable during firing. This solves the problem of the angle of departure and contributes to a high accuracy of shooting.
Abstract: A method of firing of arms which utilizes both action and reaction forces in the process of firing. The action force propels the projectile (14) while the opposite in direction reaction force is used with an independent freely moving inert mass (20) in which a cartridge case (18) resides. Since the movement of the inert mass (20) does not affect the position of the barrel (12) prior to the projectile (14) leaving the muzzle, the barrel (12) remains steady during firing, thus achieving very high accuracy of shooting.
Abstract: A single trigger sequential firing mechanism for a double barrel firearm fires the two barrels or chambers successively upon successive trigger actuation, without need for a separate selector switch.
