There has been some talk of these new Black Ops guns so I decided to buy one and open it up. The gear box is much better than what you would think of a 99$ gun. The gears where metal (was expecting plastic). The gear box was shimmed ( In the worst possilbe way ) by the factory. It definately has to be degreased. I have included pictures of the gear box, wiring, barrel and hopup, motor (both sides are blank), and piston. If better pictures or close ups are needed please say so.
