New hop not hopping

[DanBow]

Haven't really had much chance to use my Cyma emg dd Mk18 due to, in part not played much, but mainly it was a sack of shit. The couple of times that I did use it it was either too hot, even though I'd adjusted the npas all the way down or the mags venting after a few shots. 

So, inbetween other projects I have on at the mo, I've had it stripped on my bench. Dining table would be a better name but I'll go with bench. Ive stripped and oiled all the valves on the mags, presuming it was sticky valves. Didn't realise there are 2, well strictly speaking 3, valves in a mag. All taken out and oiled. I was thinking of doing a full seal replace but that can wait. Ive stripped the front end and cleaned everything and put a new 4uantum bucking and nub in. Problem now is that there isn't enough hop, even on the highest setting, so the BBs just roll out of the barrel! I'll take it apart again and check I've installed it right but am I missing anything? Apart from my marbles!

Oh, also, I haven't tried it yet but after stripping every thing down I had a proper look at the npas valve. I had tightened the bomt until I could feel the resistance, only realising after ud seen it that it needs to tightened more sonit moves the bit valve against the bolt bit. 

A see I am at the bottom of a large learning curve.

The the CGS guns are uh, boy they're rough. I dunno if it's worth sinking much more time or money into tbh.

Step one, bin/sell the mags. Consider either the Double Eagle Stanags (not the PMAGs those are ass) or the TM Stanags. They should be compatible and are just better made all round.

If it were me though, I'd just get an MWS instead tbh. The CGS isn't much cheaper but misses a lot of the internal parts that make the MWS good. You're not really at the bottom of a curve sadly, the CGS is just ass.

Not even worth getting the DE Stanags with the CGS, because the routers on CGS mags sit about 1.5mm taller, which means getting seal is near impossible - you can't install CGS routers on the DE mags either, as the CGS ones are fractionally larger footprint, so whilst you can install MWS routers in CGS mags, the other way doesn't work.

I love the CGS for being like, "oh it's an MWS system," but then they changed literally everything slightly so you can't use MWS parts and then just manufactured it really crappy

It came with 5 mags of 2 different types. 2 have the plastic outer casings with pictures of bullets inside(ripped out on day one) and 3 all metal ones with the fill valve on the back seam near the top. The plastic covered ones have the fill valve under a sliding cover on the bottom. All 5 came with purple Laylax(?) seals in them and now they're all oiled up they seem to run and feed fine.

Purple is just the bog standard colour of CGS OEM routers (e.g. https://highpressureairsoft.co.uk/products/cgs-enhanced-tm-m4-mws-gas-route-seal-set-70-degree - HPA UK on the misinformation train in that description though until the start of the last sentence, its all bollocks), Laylax have nothing to do with it.

Yep, my bad. Just looked at the original advert and no mention of them being Laylax. I think they are on my pistol mags.

If the hop unit is similar to the MWS one, you need to turn it all the way off when you take the barrel and hop unit out and then turn the hop back on after reinstallation or you can miss the adjuster and not apply any hop no matter how much you turn the wheel.

Thanks, I did notice this and did it the way you suggested. It took a lot of head scratching but the penny dropped though! Lol
