    I have a javelin m4a1 and there is something wrong with the trigger. I have to pull it extremely hard for it to shoot. So hard. Most times it doesn't shoot at all

    Try checking your trigger contacts: sometimes they get covered in a carbon build-up. (I think that's what it is.)
    This carbon build-up can mess up your trigger response.

    I have the gun like this right now. Other than that I'm not sure how to get into that

    Watch a guide online on "How to Disassemble an Airsoft M4." I like the one by Airsoftreviewer1. It doesn't need to be a Javelin specific guide: just a TM m4 model.

    I got everything apart but the last thing is my stock doesn't come off like most do. There's no screw inside and the lever doesn't pull down

    I'm not sure, I've never worked on a Javelin, so I don't know what to do from there. Maybe your GB just comes out with removal of the buffer tube.

    That's a hex screw down there. I have an APS and its the same way. FYI the bolt lock is going to catch when you try to take he gearbox out. You either have to bend it or take it out. I haven't been able to take it out( it uses some sort of pin and I have no idea how to take it out). If you have to bend it, it's likely that you won't be able to bend it back to where it was and it won't function the same

    APS = Javelin

    APS is the manufacturer. Javelin is the rebrand

    And yes that is hex screw at the bottom of your stock. Not sure what size though. Should be able to guess by eye.

    Be careful when opening the gearbox as well. Keep track of the parts.

    I have pics if you need them in my Tech Diary Thread.

    If you have them that would be greatly appreciated. I fixed the trigger problem but putting the gearbox back together was a challenge and now when I shoot it cycles but the blowback doesn't work and the bb's just fall out of the barrel

    For the blowback, you need to put the slide and spring back in. After you close it, just crack it open enough to insert them.

    As for the compression, just make sure to put silicone grease on the o rings, I know that mine loses compression through the cylinder head.

    Eh, you should disable the blowback feature. It's just another part that could break. It looks like it is mechanical so I don't think it's helping your electrical and mechanical efficiency. Do you want pictures of a properly assembled gearbox?

    Yes please. That would help. I think I'm going to get rid of the blowback. Can you take a picture of the gearbox open without the blowback

    What do you want in the gearbox? I already have mine out.
