g&p metal body issues

[hadur]

im having some issues with my g&p metal body.. i have yet to even put my gun together due to the fact that the jg mechbox wont fit into the g&p body.. is this the bodies fault ? or the mechbox's fault.. ive ordered a new magpul body from huang.. but if its the jg mechbox there will mose likely be problems regardless of body .. none of the pin holes are lining up with any of the pin holes in the body.. i cant put on the mag release, i cant get the front or rear body pins through.. im not sure what the issue is

JG is a TM clone. It "should" fit without issues. But with the very vague description youve told us with no pictures, you cannot expect us to be able to help you.

If you can provide pictures it would also help.

I'd have to say that the issue is mixing the brands.
G&P has been making metal bodies for at least 8 years, and I have never had an issue working with any of them with Systema or TM mech boxes. G&P has proven to me that they have very high standards of quality assurance, where as JG is a clone, and odds are that they manufacture their line of products to work only with their AEGs (possibly to avoid copy right infringement of the design).
D-Boyz is also notorious for this, and as an example their M14 tappet plates, hop up units, and nozzles are not compatible with TM (their set up, length, and duration are different), therefore even though TM parts are the accepted industry standard, they will obviously not work a D-Boyz M14.

See if anyone close to you has a TM shell handy to check the alignment. I'll bet that you find that it will seat perfectly into the G&P body.

I'm not saying that JG is a bad brand, you just have to be aware that their tolerances may be different....and you may have inadvertently fallen victim to this.

It's hard to provide pictures of such areas. As light barely makes it into there , it seems almost as if there's a pivot point near the trigger and when the back body nearly lines up the middle one won't and the gearbox is sitting at a strange angle , I will see if I can get my hands on a tm shell and try it out

did you put the buffer tube on?

I know I have had bad luck with the black JG mechboxes ( inside and out) not the best piece available.

G&P bodies generally are great they are usually right on the money and very well crafted.

Im guessing its your Box

I can't comment specifically on G&P Bodies, but I did just recently replace a JG M4 receiver with a metal Guarder body, and the mechbox does seem a little tighter in there than it did in the JG body. Everything lined up pretty decently, but the hop-up chamber is noticeably more snug than it was in the JG body to the point that the cocking handle won't pull the mock bolt carrier back all the way, nor will it push it back into place when it's released, and the dust cover can't close enough to lock. I'd assume that the metal body leaves a tad less room on the inside than the original JG body does.

As for nothing lining up, they should. Make sure that your mechbox is seated in the right place, for starters. I know that when I was loading mine into the upper receiver, it had a habit of sliding a little too far, so I'd have to pull it back out a bit. Make sure you pull cocking handle out a bit as you slide in the mechbox as well, so that the little notch in the handle falls into the groove that runs along the top of the mechbox.

That aside, I guess just make sure that everything else is in its proper place, like the wiring, hop-up chamber, barrel, etc. For sure, though, I'd say that it's the JG parts; they seem a tad larger than they should be.

Is your mechbox rear wired?

JG IS a bad brand. They're chinese, they'll stamp ANYTHING on a box to get it to sell (no offense to any Chinese people).
The whole 100% TM compatible thing isn't necessarily true, and if it is, it's true on paper and then lost in production and bad quality control

Better off buying a G&P complete mechbox and getting the gears shimmed, they're tanks once they're shimmed properly lol

You don't need to open a G&P complete box from the factory, they are built and shimmed fine.

As for JG i disagree, the problem is that in Canada their is incomplete information. JG makes ECHO and it is considered a quality entry to mid level gun in the states, the JG416 IMO is the best one on the market.

I'll bash JG but if you get their NEW products you won't have too much problem with them. The problem is knowing if what you are buying is from the newer production runs or if it's a JG CLONE from another factory. In many cases boxes labeled JG that I have seen in Canada where stamped with "NO EXPORT" on them. The label was used to separate the low end boxes that are VERY off spec and leave them for use inside China.

These boxes are usually exported by Chinese individuals who are locals and mailed abroad for resale by the foreign living family.

I would suggest you read a Mainland Chinese airsoft forum, their are countless and constant complaints as to why the Factories won't sell the export quality goods inside China. Locals in China like the G&P, and Japanese guns.

The last 2 I got both needed the usual 1.2-1.6mm of shimming on the gears.
Either way, better safe than sorry, especially when it comes to G&P gears, only Only takes a few seconds to check the shimming on a mechbox when it's out of the gun

Very true. The number of times that my JG had fitting issue with different parts was ridiculous.. they are SOMETIMES tm compatible, and sometimes they are not even close.

Buy good brands to begin with. The only way you learn is but making the mistake of buying shit brands to save money... and then having the product fall short... and believe me, I've bought china guns, and gear... and then ended up replacing them with better product.

so i test fitted a tm gearbox in my G&p body.. and it still doesnt line up.. closer.. but not quite.. the tm gearbox i tried is a few years old.. if that makes a difference.. this is getting rather frustrating.. the one thing i spent a rather sizable amount on.. doesnt seem to want to accept a mechbox.. if i were to buy a G&P mechbox.. how could i even be somewhat sure that it would fit and not be a total waste of 200$

Thats just one of the risks you take with airsoft. Best bet is to try and sell the one you have because it won't work with what you have, and try your luck again with another one.
