    jat, I was taking apart my v3 gearbox using mechbox.com's vidyas and I accidentally knocked the trigger assembly into pieces

    any idea how to reassemble it :(


    also how do I shim

    What do you mean in pieces. What part of the trigger assembly?

    nvm, trigger assembly was the easiest part EVAR!!!

    basically the entire thing was disassembled but after a quick vidya I took it apart and back together multiple times

    it was actually p fucking easy

    Edited:

    also pics for shimming would be nice... I'm a visual learner :C

    Could you tell something about the slots in cylinders (and lack of them) and barrel lengths relative to them and why is it important?

    I think the pill shaped slots in cylinders is to see if your spring is reset or something

    Edited:

    hang on, is the term 'shimming' supposed to be aligning your 3 gears right or is it something different? I read the OP and the term 'shimming' seems to refer to something else

    I assumed from watching mechbox.com's v3 gearbox disassembly that 'shimming' means aligning your 3 main gears right

    Edited:

    I just wanna know how to align your 3 gears right because the vidya by mechbox.com was rather vague

    those are to let air into the cylinder. They basically make the cylinder "shorter". As in a smaller volume of compressed air.

    not only do longer barrels need more volume, but heavier bbs also need more volume. I forgot to put that in.

    Edited:

    also there's a problem that can happen, i cant remember the name for it off the top of my head, but if the piston pulls back while the bb is still in the barrel it can pull air out of the barrel and slow the bb down. Ported piston heads help prevent this

    Edited:

    THERE'S TOO MUCH INFORMATION MAKE IT STOP

    oh i didnt see your edits there.

    Shimming means putting shims to raise or lower the gear.
    ask a specific question and you'll receive a specific answer. I've already typed up that paragraph about shimming so ask something specific about it. brb sleep.

    hmm I managed to replace my cyma ak spring with a weaker one but the gearbox closed somewhat funny and the fitting on the body is off by a millimeter now

    it shoots fine though, should I go back into the gearbox and reshim and shit so it fits the body better?

    Shimming won't affect how it fits in the body, you should just pop your gearbox out, you've probably got a body pin out of place. If your gearbox is shut nice and tight, then its just a fitting issue.
    I've experienced those with my SR-25, fucking AR body pins are the worst things ever.
    Either way, shimming affects internals only, unless you applied like 1 million shims for some horrible reason and you've got a 5mm gap in between your gearbox sides.

    Only thing that caught my attention was the mention of Torx screws, I've never seen them in an airsoft gun, only on my car.
    I still haven't read the OP yet anyways, so let me go do that. I really only use gas guns at this point, so I don't keep up on my AEG jazz.

    Edited:

    Super important: G&P's and TM's don't need their gearboxes opened either.
    Also, Classic Army in my opinion is the absolute bottom of the airsoft world above clearsoft and absolute shit tier, others will argue that though.

    Oh, maybe mention how huge a deal good airseal is. A proper airseal lets you get higher fps off a lower powered spring which means you get less wear. It also just makes everything better.

    Everything else checks out, but I'm not reading super in depth right now, we'll just have to wait until someone works on their shit with this guide and something goes horribly wrong.

    naw I mean like, when I put my top cover for my gearbox back into place, I could see that the metal area over the spur gear was slightly raised (as if something was preventing me from fitting the gearbox shell together, or I had something out of place and in the way) and with some effort, I managed to cram everything together (by forcibly squishing it together)

    should I leave it...? It shoots fine as of now but the fitting on the outer body is somewhat funny

    Brute force. Just something you have to live with. There is a mod to be able to change your spring without opening the gearbox.

    What I do is I stick the spring in the piston, put the spring guide on the end of the spring, then stick a screwdriver in the hole on the end of the spring guide and hold the screwdriver to get it mostly in place.

    I dunno about that. For field guns, a classic setup with an LRB with trump most everything and Polarstars are scary as fuck.
    In CQB the only advantage AEGs have are mag sizes, which are important, but not critical. I for example am planning out a hicap fed semi auto shotgun, with an external rig for all the gas ever, and its on the cheap.

    This is a bushing.

    A gearbox shouldn't be able to flex at all.

    It's not a plastic gearbox is it?

    In this case, what do you mean by no fitting. What part of the spur gear was not fitting with what.

    I dunno about that. I consider myself a fairly competent tech, especially when it comes down to my gas guns, and honestly I find that my gas guns equal if not surpass my AEG's performance on a regular basis.

    You can get an AEG up to 650 fps at 45rps with good accuracy as well.
    You can get 2 inch groupings at 100 feet with bolt action rifles.

    Just because your gas guns are better than your aegs, does not make it true for the rest of the world. Unfortunately im spouting off an opinion because I cant find all the fancy graphs and science behind it right now so you're just going to have to trust me. When I do find it (im a bit busier trying to find some information about an engine oil additive to use in a gearbox and writing up the other bits) I'll post it.

    But you're totally fair to be skeptical until then

    Well obviously both AEGs and gas guns have their pros and cons as well as their ideal application.

    You can really tune a gas gun to optimal performance just like you can to an AEG if you know what you're doing.

    Clearly if you wanted 45rps you'd go with an AEG, but you could definitely very easily get a gas gun up to 650fps no problem.

    easily, I own several 1000fps+ air rifles. Ive seen a large bore air rifle used to take down an elk.

    But that's dealing with single shot rifles. When it comes to automatic systems, it's another story.
    Gas in mag systems are terribly inconsistent. If you look at paint ball, they've gotten pretty good with gas systems. The closest thing to copying paintball is the P* engine. If you have an external gas rig, like a regulated HPA kit, then you're good to go for airsoft and you can get it just as accurate as an AEG.

    Gas is a novelty. It offers no advantages over the current AEG systems and is more costly to boot.

    Edited:

    Also this is based on the current state of the gas airsoft tech. Based on what the p* can do, if gas catches on with that kind of design, than I think people might start leaving AEG for gas.
    Other gas setups are a joke right now.

    I actually want to get a p* dmr. It's just right now, AEG is a better option than any other gas.

    Edited:

    getting a WMG from youtube, but if that's what I think it is, vortex guns are retardedly simple

    What he said.
    At most you might wear out some o-rings and they're pretty much drop in. Just you need to run a HPA rig and need a way to refill it.

    They theoretically can go up to 50rps and can be run up to either 80 or 200psi, but im guessing 80. I dont remember exactly. So you can switch your gun from a CQB to a DMR just by adjusting the controller settings

    Edited:

    also they're coming out with a version 3 drop in.

    It was supposed to be out by December but w/e

    In all honestly it seems really cool, but really expensive. I know the rifles are $600+, and I've heard the gearboxes are around $300.
