So as seen in my other thread my specna arms edge gearbox just shat itself and exploded so I'm after a replacement QD gearbox that will fit the edge series lower reciever and not take 4 weeks to arrive Any help would be greatly appreciated

I bought one then had to cancel as it appears the lonex gearbox doesn't fit specna arms lower reciever so still trying to find something that will

I just purchased a lonex gearbox it has lots of extra reinforcement around the cylinder head it isn't raduised though. Wondering if I can salvage that piston

Can anyone recommend a replacement gearbox that won't explode on 13:1 gears

I had upgraded the gears to 13:1 and installed a perun v2 but that's all. Didn't expect anything like this to happen

Yeah unfortunately, doesn't matter now though just took my gun in the garden to test the mag movement and this happened. I think maybe the feeding issues have been a precursor to this. About ready to give up

So I'm having an issue with my specna arms sa-07 edge where with certain mags namely all my high cap and my lonex 200 round mid caps I'm getting misfeeds blank shots and bb's just rolling out of the mag. I've got a game tomorrow so I am desperate to solve this issue asap

So in the persuit of resolving my feeding issue I have found that the nozzle is nor perfectly seated in the tappet plate and there is a couple of mm gap but if I push the tappet plate a bit the fit.ent is perfect and there is no wobble. This is with the stock and zci tapped plate and with the zci, rocket and stock nozzle so can I glue the nozzle to the tappet plate with some super glue or epoxy? Also the gears I have are the ZCI advanced 13:1 with the built in delayer chip but it's only a small circle in comparison to other delayer chips I have seen so qcould I 3d print a petg ring to put around it to increase its size and assist with feeding? Finally I have sanded a few microns off my rocket nozzle to match the stock length of 21.37mm would this have any impact I have attched an image below of the nozzle

Ah cheers I didn't see that whilst looking through the manual. Could incorrect precocking setting cause a jam like I have been experiencing

Just a quick on really as I could not find much online. Can you mix active breaking and precocking I have a perun v2 and wondered if you can mix both as I am trying to narrow down a solution to a different problem

@ak2m4I have ordered one of your xt m4 nozzles as you said they have the tightest fit I am hoping this combined with the new tappet plate and spring might resolve this issue

I have just checked and I do have quiet a bit of wobble on my nozzle maybe it's nozzle misalignment caused by the lonex mags

Yep seems to drop down fine this only happens at random did it with both maple leaf and zci, it happened faster on the maple leaf but I really spammed semi auto got some random dry shots and then this

Ok update tried with zci hop rubber and get jams as well maybe there is something else going on. This is what I was met with 😕 One question, can precocking have any impact on things like this as my perun has a small amount of precocking enabled

I'm on my way home now so will try all the above when I get in and if I have no luck I will put an order in for the maple leaf barrel. Will have to grab a 310mm as you don't have any 290mm left but I can't imagine the extra 16mm will make much difference in my fps and the excess will be hidden inside my mock suppressor anyway

Yep so in pursuit of getting this solved I have: swapped for zci plastic hop chamber Replaced the piston head to a rocket double oring Replaced the nozzle to a rocket double oring and sanded a tiny tiny amount off the top to match the original nozzle height. Tried the MR Hop rubber and standard maple leaf 60 Still had the same issue with inconsistent dry firing and eventually a jam. I have now ordered a new Chinese tappet spring zci tapped plate and a shorter zci nozzle to see if swapping these helps I spend £90 on the mags and when I explained the issue the return was rejected based on them staying it was my gun not the mags with the issue so I've got £90 of useless mags unless I identify the problem I do have a couple of the zci hop rubbers that you supplied with the barrel and the hop chamber so when I get home I will get one of these installed I see how it goes. I will also fill the mags as much as physically possible and leave them till Saturday when my next game is and see of that helps

So cutting some coils on the mag springs helps?

Yeah I grabbed it from ak2m4 I think I've been his no.1 customer over the past months spent about £200 on barrel gearbox parts ect. He is the only one with the maple leaf barrel in stock at 310mm if I grab one today maybe I can get it by Friday fingers crossed. I have done a bit more research and some people are only able to use the ZCI hop rubber with zci barrels without issue and I'm using a maple leaf 60 o do have a few zci hop rubbers floating around at home that came with my zci hop chamber and barrel so nay give them a go it might just be the hop rubber giving me issues

I have noticed that when it jams there are 2 bb's trapped and they don't move at all no matter how many times I fire I might just grab a new maple leaf barrel but the 290mm is out of stock everywhere so may have to grab the 310mm and have an extra 16mm sticking out

It's definitely only the high capacity mid caps that I have that are having feeding problems. How do I fix mid cap syndrome? Would a shorter nozzle new tappet spring and new tappet plate help?

I am using a rocket 21.4mm nozzle would grabbing 21 3mm nozzle help fix this qnd maybe a new tappet plate and spring?

Yep, only happens with my lonex mags i get dry firing and eventually a jam, they are higher capacity 200 round midcaps whereas my other mags are 140 round or high caps they all work flawlessly but when I put my stock barrel in my linex mags feed fine

So my ZCI barrel is having issues with my lonex 200 round pmags it's misfeeding a getting blocked I've tried prometheus bucking malle leaf macrom a MR HOP with the same result. I want to use my lonex mags so will have to grab a new barrel, the maple leaf 290mm is out of stock everywhere so I was looking at the mad bull black python v2 us this any good? If not could someone recommend an alternative

Wicked cheers guys

That's awesome thank you, also is it normal for the battery to get warm under use? I don't mean burning hot or anything but just noticeably warmer to the touch after spamming semi and some burst fire
