"So far so good in a Umarex 416. FPS is a little weaker than advertised with the recommended G&P motor. with .20 and 7.4 Lipo it's shooting around 320.

Good construction and easy installation.

-decent contruction
-durable components
-o-ring nozzle
-AR latch doesnt pop out
-well greased
-nice compression
-might as well put in 10$ more and get extra parts then spend 60$ for just the shell

-SPRING IS CUT for the FPS, must get new one or it will mess up your internals later on
-no ball bearings on piston head or spring guide
-not really perfectly shimmed, was still able to move bearings up and down
-trigger seems like its rubbing on the wires due to the fat insulation
-for some reason my box didnt come with spare parts (motor contacts, heatshrink) maybe they forgot it or something

"Alright not much to say so lets get to the pros and cons


Deans wiring

28 rps on a matrix 3000 high torqe motor

comes with lots of shims (I love shimming the gears for some reason)

Great trigger contacts

Near perfect air seal


The piston wasn't even bad I replaced it because It looked like cream cheese but either my madbul piston swiss cheesed and 2nd to last tooth removed with a ball bearing piston head is a dream in any v.2

Gears are good but their axles are not

Overall: Don't get this gearbox unless you are a tech G&P is a lot like Tokyo Maurui, it was made for upgrades, but once you get it shimmed and set up with something strong like I have like Echo 1 18:1 gears and my madbul piston, Everybody and their mother with a KWA is wondering how they are getting destroyed in reliability and performance.
