The Avatar Universe Hornet H-2S Gas Bro Conversion Kit for use with the aisoft G18 or G17 Pistols GBBs or AEPs is available in Japan and Orga Airsoft takes a look at one of these... "Introducing a conversion kit that turns your Glock into a science fiction submachine gun! Mass Effect (Mass Effect) It's often thought to be a kit with a design based on the gun that appears in PC games, but with the inclusion of an electric handgun, it quickly changes into a compact electric gun that can be used indoors and CQB!
