I made new one, look into first post. Its some kind of modern-weapons presentation by models, you known like in car salons or expo. Just have that idea and decide made it (why not?) Claudia still make model pictures and i new guns, so we mix that ideas together heh.
Its energy weapons so, plug is for battery, they are heavy so designed to hold them in backpack. Ofcourse models dont have full army equipment, she just show that gun (even hold it wrong way)
