Heavy Barrel RU got a prototype version of a launcher for the the Kick Shell from TAGinn to test... "Based on the grenade launcher for 12K gas shells, I present a prototype of an airsoft grenade launcher for a carbine (compatible with the RIS interface + there is a transition to m-lock). The ammunition used is the Kick shell launcher from TAG inn, grenades of the KS series. If desired, the grenade launcher can be easily reconfigured into a single-shot pistol and retrofitted with a buttstock."
