<p>A muzzle launcher launches spin stabilized projectiles from the muzzle of a firearm. The muzzle launcher attaches to the muzzle of a firearm, and comprises one or more bores; each bore containing one or more projectile. An existing impulse cartridge provides the gas pressure necessary for launching the projectiles. The design of the muzzle launcher comprises selecting the volume behind the projectiles, the mass of the projectiles, and the length of bore travel in addition to the propellant charge used to produce the desired minimum and maximum effective ranges, recoil energy, and trajectory. The bores are optionally rifled to provide spin-stabilization of the projectiles.</p> |
