Works great!

Solid! No warp or wave, comes with a dual o-ring aluminum cylinder head, aluminum o-ring nozzle (21.25mm), ribbed stainless cylinder, full metal rack piston, aluminum piston head, and a M115ish spring. Gears are 16:1 steel with what looks like a thin paint, so they are likely PMI but I can't be sure. The tappet spring seems normal strength or better, and the tappet is fiber reinforced polycarbonate - no replacing needed! The gearbox itself is microswitch type, so fair warning - you can't use internal ETU's with this gun! You'll need an external one like a Gate Warfet. No corner breaks up from the factory either, you'll have to relief cut the cylinder corners yourself.

All in all? Solid as hell. A great gearbox to build on if you're using an external mosfet setup. It comes with enough awesome parts out of the box that you won't have to change much at all.

So far so good, absolutely no problems. It miiiiight be a little tight with slight whining. Very slight. This product is amazing and has held up the past few months. Will purchase again if I need an easy installation and upgrade!

coupled this gearbox with a ZCI motor both brand new, the gears didn't survive a single magazine, I opened the box because it made some noise and was locked up, what I found was the spur gear that drives the sector gear, all of the teeth had come off. The good, I like the trigger switch even if it makes this gearbox somewhat propritary, coupled with an adjustable trigger and a mosfet would make this a very nice setup. The gear quality does not justify the price for this gearbox, maybe I got a bad set of gears, I am going to radius the corners which at this price should have been raised, before assembly
