I'm scared to superman into a bunker and risk scratching it...
..so yeah, nothing.
When I ordered the body I noticed that they required shipping insurance which is a good move. Not only that, but primary shipping is USPS Priority, so anywhere in the US, you will get it in 3 days. However I got mine in only 2!! When I openned it up, it looked so much better than on the website. The milling cannot be captured very well in a photogaph. It has to be seen and moved around to really be able to capture the beauty of it.
It was easy to install, except for having to switch the stock solenoid hose with the one that is provided. The new hose is only a couple millimeters longer, but odd enough, it is required for the rear 90* manifold to function properly. After that was done, I tried the BOB feature. One word... Awesome!! All you do is remove the rear grip frame screw and loosen the trigger frame screw right in front of the trigger. Then, unscrew the body's back plate and out comes the whole firing can, delrin donut, and bolt! Why smart parts didn't impliment something like this in the gun's initial release I will never know...
If you have the money (mine was $125 shipped) and are tired of the plastic body, not to mention being tired of having to take your whole marker apart just to get to the bolt, don't cheat yourself... get this body. Not only will it turn heads, but it also has some nice functionality.
