Honestly I don’t really want to. Last time I was there, they belittled my M16 build and told me they thought it sucked. Also, while directionally correct, the guy there was totally talking out his ass about that EBBR gearbox. Besides that, this thing is clearly not ever going to be competitive. I don’t think that jamming problem is solvable. Maybe if I get just the right gels but fuck that. I’m going to 3d print a lower and frankenmod it into some sort of fucked up stockless machine pistol and use it purely as a toy.
We are trying to help best we can. Sounds like you’ve had a bad hair day.

Huh ok, that’s odd about the fitment, one would think if they sold the gearbox separately they would have it do it could fit a standard receiver or at least advertise it as not being compatible, maybe that’s why they advise having a tech fit it due to having to modify the shell.
Pretty sure the stand alone gearbox has the M5 screw hole on the back so maybe they didn’t mould it on the nylon build, some receivers just use a M5 nut on the inside instead of relying on the spring retainer, SLR do this from memory.
Great customer service to be talking trash about a customers build, especially when they themselves don’t know what they’re talking about or selling. WAT always came off as Milsim Elitists to me, not willing to deal with anyone not able to drop $1k on a blaster so it looks 100% accurate to the real thing.
Only had one in store interaction with them myself and don’t have any intention on dealing with them again just based service, also they’re like an hours drive away.
If you work at or own a gel blaster store you should never trash talk someones build! …unless it has a drop stock or is a paintball looking speedyboi thing. (That is a joke, but not for me!)
I have only had a few dealings with WAT online for parts, so I can’t comment to any service beyond what I ordered came.
Would be interesting to get an ATM gearbox kit and see how close it is, and if it is an actual ATM box. I always found it odd they make a gearbox that doesn’t fit anything, and that is the feedback I have seen across the board so far.
There is nothing like crafting and filing until it works though!

Yes re WAT I’ve never been there besides online service is good.
But ah to treat customers like low lifes they are going to loose them very quickly. I didn’t know this and apologies was only trying to help. As some said they are great.

Oh, the one you got is definitely below-par. For a normal 416 EBBR, it shoots between 230-250fps, so far I have not got one shot below 210fps.
The gearbox is a knock off of the LDT ATM but the quality is near that one. Basically, it is buying the gearbox, the shell is far from good.
It only takes hardened gel balls. Milky one won’t work. It does not jam unless wrong gel balls or the one you got is having issues as I does not have one that jammed so far.
If you have questions on the issue, I might be able to ask around as the supplier is easy to reach out.

Just a note here, the LDT ATM one isn’t coming with a full metal gearbox housing as well.

I have an installation guide in Chinese, if you don’t mind, I can send you one. It is a moderate level of mod.
Oh really? Just looked like metal from the images, thanks for clarifying.

I can’t even open their website… did you buy in-store or online?
Ha, did you look at the one review someone left on it 
Looks about right for them.
And yeah I think “Gel Ball Warehouse” had actually closed down last year, so must of been GBU which would explain the poor performance cause it seems anything they sell I just bad by proxy.

It’s a pretty copy paste description. Don’t know what a nylon metal is? It’s not a metal gearbox as OP pointed out, OP also didn’t get any iron sights as it’s listed.
It sounds more like a faulty unit rather than false advertisement on fps thou as AK commented too. I’d say OP should of hit up the store about it’s poor performance ootb but if it was from GBU good luck with that.
It’s the “fire breaker” description that did it for me as a copy paste effort 
It only has to have a pot metal outer barrel for it to get the “nylon and metal” description these days.

But it’s hardened Nylon handguard What did they hammer forge some Nylon or what didn’t swing hard enough
Anyway hope the OP can get it sorted.
I had to remove a heap of material to get LDT ATM box into a classic army xm177.
First time comment in this forum. This might be the EBG gearbox. Separated gearbox have better polish than the one come with HK 416 blaster ( what your own maybe). I think you can try to hone the lower receiver just like the guy at this video. He got a separate gearbox and fit it in m4 Sijun receiver. For the gel, try ultra hard gel ( the blur one) ?. Hope it helps, this is the name of youtube video:
