"pretty easy to see that its actually a true cnc gearbox, its very light, crazy strong. it runs my Prometheus 170 with no issues , im loving the micro switch on it as well, it gives a very short and light trigger pull with fast response, and the wiring on it is a rather nice braided silver, i had no issues swapping this shell into any of my v.2 compatible guns and overall its just a good shell, if your looking to make your gun ludicrously strong or to just flat out never break, id say this is a good and very attractive looking option

"The gearbox itself seems very well built. Very light weight. But the trigger unit or wiring fried one of my batteries. After i got the internals installed i plugged the battery for a test run. As soon as i plugged the battery in, the battery started to heat up and sizzle. If you get this id advise putting a fuse in there somewhere.
