Don't buy more once you go down the slippery slope there's no way back.

ok it was when i posted

Zero one has g&g mags in stock https://www.zerooneairsoft.com/product_info.php?products_id=4035

Ok then this is probably what the gear box looks like https://www.guay2.com/en/product/detail-1903 etu is internal you need a tech. If it's new take it back under warranty.

Does it have blow back ie did the ejection port cover move when firing?

Unless you can confirm the model it might not have a etu.

It's not that difficult to take apart. Two body pins and the mag release hold the upper body and stock on and the the gear box is held in by the selector switch which is held in place by a grub screw in the right hand side selector switch I think then two screws in the mag well.

Have just searched or have 7ou messaged them?
