"Gaylord comes with a bone of his own"...brilliant

the general consensus is you don't need a thrust bearing on both the piston head and spring guide, it won't do any harm but it will put a little more stress on the spring. again every aeg is slightly difference, worth experimenting with both. personally i only ever fit the single bearing on the spring guide.

JG's use very cheap springs, they generally are quite thick and short, made from cheaper "piano wire", hence can degrade quickly. Firstly you want to grab a new spring, ideally grab one which has been tested by the seller so you know what to expect, that way you can rule out issues. 260fps with 0.25g is pretty low, that's around 290fps with 0.2g. My guess is you have a couple of issues with the airseal together with a degraded spring. Does the AEG use a quick change spring? If so that's the easiest route to increase without opening the gearbox.

Let me know how that Gearparts M105 spring works out for you, plus any problems. I've not opened one of the new DE yet, will get hold of one soon though.

I've had the E&C version in the past and it's pretty decent, just upgraded the motor and hop rubber. It's the cheapest AEG they do, if you can get it outside UK you should be able to get one with the COLT markings

I haven't used one myself, they have been around for over 20 years, they don't have a great reputation though. I do hear the motors are pretty good though. What worries me about sites like JustBB is they don't give any internal pictures of the gearbox, not even an external picture. It's the most costly part of an AEG

SRC rebrand if I remember right?

Whole load of memories just came flooding back

@Cannonfodder Pretty sure I've got a 16K in parent attic somewhere

Upgrading the Atari ST to a C64, they can only dream about an Amiga 🙂

I've wondered about this as well. I would guess since Aliexpress is the payment provider everything goes through them but who's to say they actually pay the UK government the correct fees. There's no way they can check, when you look at an Aliexpress label there's no indication of any tax paid. So Aliexpress make a little extra from the 20%, UK government make a little extra from whatever payments are made and can reduce checks on goods coming in (extra saving). The only saving grace here is if you use a Chinese or HK website who don't charge UK VAT their side, their might be less checks so less chance of import tax and duty.

Hi Alex, as you're mostly playing CQB then perhaps 22TPA motor is the easiest upgrade, good on battery efficiency and low on heat for the semi-shots , for extra snappy'ness you could run a 11.1v but you might then need to upgrade the gears and piston. Can add a Mosfet if you wish but it's not 100% necessary.

The best I've come across is Super Lube Silicone, stuff is fantastic and long lasting, really weird properties as well, not sure what they put in it. I also use Sealeys, it does the job but doesn't last as long.

DHL though, that's gonna sting for sure. I asked one broker last week to quote me 60kg (non rifs) from HK and got back £1350.000 lol...Hopefully they have negotiated a decent rate, however DHL are firmly in the won't ship replica camp so not sure what they can do about that.

@colinjallen shipping cost clearly gone through the roof, £51 sounded high but I just checked my DSV / UPS account and for a 4kg package pickup from Wroclaw Poland to UK came out to £70. However do the reverse, UK to Poland via Parcel2Go and UPS standard is £27 (£50 insurance).

ideally you'll need to open up the gearbox to check the components, do a full inspection etc. if you're not ready to open it up then you can check the hop rubber (bucking).

22.22222222222222% ain't bad indeed if that includes UK VAT, duty and handling charge as I believe Polish VAT is 23%

if you're flush with cash then sure treat yourself to something new, but in general there's isn't a gearbox issue which can't be fixed with new parts and time etc. Your problem could be a number of things, slipping gears? ARL perhaps. Best thing you can do is make a little video of it firing and another one with a look inside at all the bits

as skara said it's got the molded nub on the arm now so not hugely beneficial for flat contact-patch buckings. last few days I've been testing my new nubs and bucking with lots of different combinations of gearbox shells, chambers, nozzles - it really is a nightmare of a minefield. If you do a lot of builds then it's really worth keeping a few different brands to hand.

Welcome buddy, you'll find lots of friendly players, have fun

Not yet been but a few of my local customers / friends have, they really like it. doing some good stuff

@Rogerborg I was going to say that the ZCI 70 is pretty well molded using silicon, the one in the picture looks more like it's made from more of a epdm rubber

that is super strange, never seen that before. I just checked a few of the ones I still have here and they all have the nub and ridge in place. It's possible that you do have a molded mutant on your hands there

show us your piston, don't be shy

From my own personal experience I don't get too hung up on bore sizing, especially with lower price cheaper barrels. If you took a bore measuring tool you'd probably find it was nowhere near the specified size lol.... As for maintenance I'd take out and clean after every game (that's just me though).
