Hello Everyone, Today I have an Mp5K BODY ONLY. It is an Echo 1 SOB II. It comes with everything you see in the picture, the gearbox shell, trigger, and trigger spring. It had an F1 in it, which I still have the nozzle to if you want it. The body is full metal and has a retractable and foldable stock. Looking for $65 shipped. Hit me up with questions! Aaron
