Huang's JG mechboxes

[spartan117]

Has anyone purchased Huang's JG m130 mechboxes? Are they reliable? What parts do you recommend to swap out?

[Qlong]

I have, and put in a sorbo pad, 1000+ shots no problems.

Considering the country of origin, my guess is the quality control will be hit or miss. You might get one that outlasts a TM, you might get one that dies after less than 500rnds.

Personally, spend the little extra and build a mechbox from deep fire, modify, or other parts. Far cheaper than SystemA, Prometheus, Guarder, etc. but better in the end.

modify and deep fire are both from China, just like JG, that contradicts you're first sentence

I have experience with JG mech boxes, they are actually very good with surprisingly good parts.

Are any modifications or cleaning/regreasing needed? I seriously hate opening mechboxes...

[T_A_N_K]

Reshimming it and checking the grease in it would probably be a good idea.

Actually it doesn't. If you have ever seen any JG internals and you have ever seen any of the modify or deep fire parts, it would be quite obvious. Though they are both made in China they are made to very largely different standards. A JG mechbox can be had for less than $100, building a mechbox from scratch from modify or deep fire parts would run far more than that, maybe around $200. Plus you get far better shimming, double check that parts line up properly, and much higher quality grease (all because you do it yourself.)

Just think about it for a second.....

-Metal bearing spring guide instead of cheap cast solid metal spring giude
-Polycarb piston with multiple metal teeth instead of nylon
-Chrome plated low friction piston instead of brass (sometimes with flash from the manufacturing process)
you can say the same for any part of the mechbox, plus the shell itself in JG guns often have casting problems and small air bubbles, never seen that with any modify or deep fire shells.

Not just airsoft, but anything really, just because its made in China doesn't mean its the same. My $450 WACOM tablet is made in China, does that mean its the same quality as the crap $50 tablet I can buy in China town?

I also have experience with JG mechboxes, they have the highest failure rate of any mechbox I know of. Yes the failure rate is still quite low, it is still a lot higher than SystemA, TM, CA, G&P, etc.

dude, I have no idea what you are saying anymore!

Yeah, just reread that and it doesn't make much sense, damn ranting, lol.

Mainland Chinese QC is lower than Japanese and Hong Kong. The JG preassembled mechboxes are from what I've seen low quality knock offs of TM, so no real performance parts, only thing good about TM is the reliability. If you make a mechbox out of Modify or Deep Fire parts you can test fit everything ahead of time, check the items for manufacturing faults, do the shimming and greasing yourself, etc. etc. It would end up being far better than a JG mechbox, though cost probably more than double. Mainland Chinese performance parts are still better than Mainland Chinese discount parts. It would still be better to use Japanese parts, but modify and deep fire have so far impressed me fairly well with cost vs. quality, just need to pay more attention and inspect more when you receive them than you do with Japanese parts.

My original comment about country of origin and QC was more in reference to test fitting parts, not installing parts that had faults in them, bad shimming, bad greasing, etc.

And my WACOM tablet reference doesn't work, turns out its made in Japan.

I got one of these mechboxes for my C8, and it has given me nothing but grief. I installed it, fired a few shots, and the thing locked solid. I thought perhaps it was the spring, so I installed a Prometheus MS110SP spring. From that point on, I had no more jamming issues. However, that's where the other problems started.

I install the mechbox, and it works fine for a bit.. Then I'm unable to fire in auto anymore. Regardless of where the selector is set (except safe), it fires in semi only. It wil do that for a bunch of shots, then the trigger will sort of 'block' and it won't fire anymore. I can depress the trigger past the 'blocking' part, but still no action. Removing the motor from the grip and reconnecting it confirms that no power is going to the motor.

I've tried everything. I've replaced the trigger, cutoff lever and selector plate, and still get the same results. I'm at a loss.

While the mechbox shell itself seems nice and solid, as do the gears and other internals, I just can't get the damn thing to work right.

there we go, now you make sense!

or...

...from what you're describing, I replaced the switch assemblies in two different JG mechboxes what were doing the same sort of thing and it worked (at least for now). On one I also swapped in a TM cutoff lever and on the other the just the switch assembly (actually just the top block that gets pushed into the contacts). The switch assemblies (and parts of) were "old" stock TM ones that I had laying around from various builds.

It's only another $20...

Yeah, I didn't buy any new parts for it. It was all old TM I had laying around from my broken TM mechbox this one was going to replace. The last part I'm going try replacing is the switch assembly. It's the last part I can try. After that, I'm junking it.

On a side note though, I really like those JG motors. Regardless what mechbox I'm going to end up using in my C8, I'm planning on using the JG motor. This is the same motor I have in my JG 416 (the one that came wiht the mechbox). I tried swapping back and forth between the TM EG1000 motor and JG motor, and the JG feels much more responsive with higher torque.
