System For Air-Based Propellant Gun Adaptation

Abstract

A pneumatic firearm firing system is utilized to discharge a projectile from a firearm utilizing propulsion provided by a pneumatic propellant. A pressurized projectile retainer is utilized to concentrically hold a projectile under pressure due to a quantity of compressed gas provided from a compressed gas vessel. The quantity of compressed gas is held within a fluid conduit that is engaged into the pressurized projectile retainer. The pressurized projectile retainer is engaged into a front end of a firearm bolt. When a trigger of the firearm is pulled, a flexible collared portion of the pressurized projectile retainer is projected forward from a rigid collared portion of the firearm bolt, releasing the projectile from the pressurized projectile retainer and causing the projectile to be propelled forward due to the propulsion provided by the quantity of compressed gas.
