no the 416 ones are systema clones i now know their is a huge diffrence on the new fets one any news on what they shoot or is it stock jg around 400 and they come with metal spring guides correct?

I was looking at a new JG Mechbox for my stock TM SR-16 Knights baby. It's a Complete Version 2 mechbox /w high power motor set (Rear Wired) and it's Jing Gong's new Black 2008+ version so I don't know if it has the MOSFET's or not. What is the general consensus on upgrading to this mechbox/motor combo?

Go for it. JG is a good brand.

Thanks for the "go for it" advice Styrak, but I have heard of issues with the JG mechboxes and the fact that they are not as stable as the TM mechboxes. I just wanna get more FPS out of my TM SR-16 and the drop in seems to be the "easiest" solution but I don't want to add any problems to the perfectly functioning gun...just want some more FPS (currently 280 FPS from the stock TM mechbox)

Hearing issues is one thing, but trying it out and having it in your hands is another.
There's basicaly 3 models of it.
1 - Black reinforced gearbox with plastic bushings
2 - Black reinforced gearbox with metal bearing bushings
3 - Black reinforced gearbox with metal bering bushings + mosfet

Number 3 is the newest one. But if you feel that it's problematic with you, buy a new Systema complete gearbox which run for US $579.

lol maybe I'm just lucky that i never ran into these breaking piston problems and v2's cracking..

I have a Dboys gearbox running in my AR right now, and it's pulling 387FPS with a lipo using Element 300% Torque up.
And I've fired thousands of rounds, and short bursts on the lipo. Even holding it down for 4-5 seconds. Nothing has broke yet. Hmm China stuff aren't that bad nowadays.. lol

I like the JG drop-in mechbox, but beware. Even being reinforced, it won't last with that M130 spring. Downgrade to something more realistic like M100-110 instead, and preferably, install a sorbo pad. I had my mechbox in my JG 416 crack at the nozzle from the stock spring.
