Message me and I'll sort you out with some GPA springs if you want

Welcome, what part of Texas? Lived there myself for a year, good fun.

@Aj698 damn that's some good consistency, not jealous at all 😃 What spring was that with?

For context I had lazz send the gears back to me for testing, not sure he mentioned this in his videos. I tried them in an e&c, lonex, and v3 JG gearbox and the spun perfectly, no issues at all, videos are up in anyone is interested. All I can put the problem down to is either some incompatibility with certain brand of 13:1 or as @Floperator says ensure the bushings are level. Seems like @Rogerborg has a neat solution. I wonder if its only 13's that cause the issue?

some brands of gearbox just don't like certain ratios and certain types brands of gears I've found over the years, it's why I stock both SHS and ZCI. If you can, try the gears in another shell you might have, or if you got the gears from me then feel to send them back to me and I'll try them out.

on the other part of the shell is there any reinforced material ? sometimes this blocks 13:1 gears from working due to the size of the sector gear

empty pls

take a pic of the inside of the gearbox shell please

appreciate the thanks, noticed more than a few "hit and run" advice takers recently. Glad you got the power problems sorted out, a nice feeling when you suddenly get the thing working

Good longer strength steel screw works for me. Never had any problems personally. Your AOE doesn't look too bad, maybe just leave it.

why don't you add 1 or 2 more shims to the piston head? you said there's no more space for washers, how come?

Does the current Nuprol Pioneer Defender still use the old micro-switched gearbox design?

I see you posted this on one of Facebook groups also, I only glanced at a few replies are comical. It's a Specna arms right? Without fully knowing what spring is actually installed it's difficult to know how bad the problem is. You mentioned a M100 but the ship could be just saying that judging on the fps drop. They could have fitted the M120 or M110, plus different brands are different powers etc. You say you've used it for 4 games, over what period of time? Probably loss of compression in the piston head, cylinder head, nozzle, bucking etc combined with the cheap Chinese spring losing its power. Could even be something as simple as a regrease and oring. If still in warranty the store should have opened it up to check though, wouldn't have taken long.

Do you have a set of vanilla 16:1 or 18:1 you could just swop out?

Be interested to try that little wedge - does seem the simplest solution. I just tried the locking nut that comes with the Retro Arms hop unit however it does nothing to keep the chamber and barrel aligned.

It is indeed a problem. The wall thickness of a Macaron edges on the thinner side as well so there's even more scope for the bugger to move around. I wonder if if could use 3 small grub screws? Think it would work?

I imagine that the airport staff here in the UK won't be able to check the UKARA database. Maybe it's a good idea to speak to your local site, ask them to send an email to your email address stating you're a player at their airsoft site. Or a phone call to the registered number on their webpage who can then verify you (hoping someone picks up).

@KarlosM15 it arrived today according to the tracking, give us a pic when you get a chance 🙂

@PureSilver sounds good, seems they have adjusted the games and fixed the issues.

I did go to the opening event, or may have been 2nd but left lunchtime as it was just too crowded (think numbers were around 40) - spent most of my time standing in the stairwell sadly. Hopefully they've reduced the numbers a little as I think would play quite well. As the norm difficult with a CQB site where you have to balance player numbers with the cost of running etc. Chatted with another group who also left lunchtime as well. Sounds like they've addressed some of the issues now. @PureSilver how many players were on your day?

I did wonder this as well. I've never seen an E&C with a closed cylinder before, they don't advertise it in their catalog either which is why the 500mm inner barrel threw me a little. @KarlosM15 let us know when you fit the new inner barrel will you please.

@Speedbird_666 thanks for all the pictures and writeup, had my eye on this for a while and really love the looks and ergonomics, although give me the fixed stock version. The PTS EPG integrated grip is nice and cheeky. Do "standard" gearboxes fit btw?

@Adolf Hamster oh yeah just seen on the product description page. 🙂

Why do you need a 500mm inner barrel bud?
