Patent ID: 7412975

Claim:
A handheld, gas propelled missile launcher comprising: a barrel having a durable, one-piece, substantially cylindrical bore, said bore having a muzzle end including rifling, transitioning into said bore's surface, a ballistic module dimensioned to be received with said bore, said ballistic module including a payload spaced from one single gas cylinder by a gas cylinder opening means, a handle at an end of said barrel adjacent said gas cylinder, said handle including a spring-biased actuator stem remote from a sealed end of said cylinder, to move said gas cylinder against said opening means, and a retainer with a conical bore attached to a disc-holding opening, and a plurality of bores for gas passage, wherein said barrel has a muzzle area and said muzzle area includes an interior rifling configured with elongated channels with a radius corner at each side of the rifling channel spirally deployed within the interior bore, said rifling providing rotation on a propelled fabric projectile to determine improved stability of trajectory, improved range due to a 25% velocity gain and prevented loss of energy up to full penetration, and wherein said launcher further comprises a rotary buffer-safety device, comprising an annular band with a thumb tab, said annular band being captured within an annular track way at an end of the barrel and adjacent to said barrel, said annular band preventing the stem from advancing far enough to contact the cylinder unless the safety device is in its unlocked position whereat its port aligns with a track way for an actuator.
