Hope you get it sorted. Keep us updated.

Do it mate. The scamming B'stard deserves no chances. He knew what he was selling you.

That's a pisser! Could you, at least, charge back on your card or file a dispute on paypal? Hate seeing people get ripped off!

who read out in an Irish accent? I did! lol

Not what your asking but did you not throw it back at him and get a refund? EDIT: This one? - https://e-tactical.store/en/gearbox/9787-jg-works-metal-gearbox-for-mp5-series-a-x102.html

You dont need to tell me what a kerfuffle its been!!! 🤣🤣🤣

Ok, I heated the end of the spring and compressed about 15 mm ish. Put it all back together and it was totally dead!! Stripped it apart, and slipped, it all went flying all over the floor! Bollocks!!!!! So reshimmed, rebuilt, reassembled and it shoots lovely but stitting at a reasonably consistent 305fps on .28s so 1.2j. Still a little spicy. It was around 320fps on .28s - 1.3j. I've had a look but can't find a spring thats 160mm so I'll probably just heat/compress a little more. Not today though.

Whats a "human oran" and why can't you shoot it?

Who are your UK dealers?

Just looked at your website too. Seems legit. Theres no option to purchase directly from you, are you the manufacturer or a distributor?

I clicked on it and it played the video. Didnt have a clue what was going on though. Lol

Hi, Welcome. Are you from, or affiliated to, a particular manufacturer?

It looks like it's doing what it's supposed to. You pull the top slide backward and it compresses the spring, as it goes forwards it loads a bb (not bullet) into the barrel. Then you pull the trigger and the spring is released pushing the bb out. When you've pulled the top slide back, and let it go forward, does the spring release when you pull the trigger?

No.

Just an afterthought, G&G use 160mm springs but every aftermarket one seems to be 175mm. Unless I fit something like an M80 and hope that with it being compressed to 160mm makes it equivalent to an M100/90/95. I don't think the actual spring rating is that important as long as it's at the right fps. Not sure if rate of fire would be changed with it being a "weaker" spring but, again, will compressing it not affect that???? My head is about to fall off! I'm going for coffee!

Only got one bearing. Would removing a mm or 2 make that much difference? I'm looking at shortening my spring by about 17mm? I need to drop about about 20fps. Really grateful for all of your input too. 😁

That's a good shout. I might try that before cutting. 👍

Yes, me too. I've got heat and files so I think I'll cut it with my hacksaw and file it or cut it, heat it and hammer flat.

Right, I'm enjoying this home teching malarky but there is so much to learn. Like not all springs are equal. Like not equal in length!!! I suppose common sense should have told me that a longer spring, even though a lower rating, would make it more spicy than the standard m110 spring! Who knew that G&G use a shorter main spring? Well, I did actually when the seller told me! But did I realise the implications of that! No. Well I did but it was after I had bought the new spring and wanted to get it put together. Impatient? Me? Absofuckinglutely! Anyway, got it all put together and it shoots lovely. The protruding bearing is not an issue at all. My delivery of parts from @ak2m4 just came and although I am very happy with the service and cost, I didn't need it but will definitely being using him again. Thanks Pete. So, no pics this morning but while I start searching for springs in 160mm length, can anyone point me in the direction of some? Oh, I'm probably going to take the new spring out and cut 10mm off the end. Got nothing to lose at this point!

Its probably the exhaust valve. If you can, take it out and oil it or replace the o rings.

Nope, inserted the right way. I did continue to play with it before i came to work and the selector does sit flat ish on the gearbox. I've put it back in the reciever and, apart from forgetting to put the selector spring back in, it selects fine. I'll finish it off when i get up tomorrow and report back.

Ok, I really shouldnt be having a look as I dont have a good track record of doing things when I'm on nights . . . but Ive just pulled the selector plate off and the underside is already recessed in the two areas that sit over the bearings. I'm going to leave it for now and put it all back together properly over the weekend and see how it goes. 👍

Last night shift tonight so I'll pull it apart at the weekend and measure everything.
