Chimera M203 full metal under barrel grenade launcher (Double Bell M203 with RE-BUILT trigger to fire TAGinn VOG grenades) is sold as a pyrotechnics accessory for both airsoft and air guns, hence is subject to age restriction of 18 or over. Pls note, the original factory firing pin is not pushing far enough to initiate the launch. Our price includes full metal M203 (£110) with 3 types of mounts + TAG Evo Shell Pro Co2 cartridge (£120) or TAGInn KC spring-loaded cartridge (£168). Pls visit Ammo & Air page for a selection of suitable grenades and extra cartridges. Despite trigger modification (the firing pin was made to push further), Chimera M203 remains fully compatible with MOSCART gas grenades (!)
