摘要

Set for temporary modification of firearm into firearm simulator powered by compressed gas for simulating shooting comprises a combination of the real firearm components (10, 12) and the simulated firearm components (10, 12) including a simulated barrel unit (24, 34, 102, 724), the simulated barrel unit includes a separate magazine (48, 60) for tightly accommodating a limited volume of compressed gas, a filling port (50, 62, 823, 650) for filling the compressed gas magazine (48, 60), a metering valve (86, 98, 120) triggered by a firing mechanism in the firearm (10, 12) to release compressed gas from the magazine (48, 60) to simulate firing from the firearm (10, 12) and a leading end for mounting the laser unit (52).
