V2 firing full auto on semi

Acid44 · September 29th, 2013, 22:56

About a month ago my gun got a bit wet, and since then it's been firing full auto on semi. I've looked at everything (aside from opening the gearbox) and all seems to be fine. I made sure everything was dry before firing it again after it got wet, aswell. Any ideas to the cause/where I should be looking for problems?

Standard procedure is to first replace the cutoff lever. If that does not fix the problem, then replace the sector gear.

there is plenty of video of people "over the beach"ing an aeg... while it probably isn't good for it long term, it shows that aegs can get wet and even be completely submerged under water and still operate.

I would not recommend it... but people have done such tests.

I doubt getting it wet has contributed to your full auto problem.

Do as venture as recommended. The cutoff is the first suspect. If your gun is about a year old and a king arms m4... then it's a very definite culprit.

If it's spotty-auto(sometimes burst or full) it could be arcing of your trigger contacts. What sort of battery are you using?

I'm using the standard 8.4 which came with the gun, which is a Lancer Tactical M4 RIS.

It isn't bursting or full auto-ing, it's either firing properly semi, or just full auto, and full auto works fine on its own (if that matters). Will check the cutoff lever when I have some free time, thanks.

Full auto in semi is ussually the cut off lever.

If you need a doctor to fix it I'm in the area

A broken selector plate also causes this.

Acid44 · October 4th, 2013, 20:07

Wouldn't that cause it to fire full auto all the time, though? It still fires semi about half the time.

Adamlxlx · October 4th, 2013, 21:08

Shiat sorry. Apparently i am lacking reading skills today. Even so how do your contacts look?

Acid44 · October 5th, 2013, 00:31

Haven't had time to pull it apart yet. Hopefully tomorrow, maybe tonight

Acid44 · October 20th, 2013, 21:26

Alright, finally have some time and have it apart now.

Selector plate looks fine, trigger contacts are perfectly clean, cutoff lever looks fine and it working properly. I don't see anything wrong in here at all. Any ideas?

Do you have any experience with guns? How do you know the cutoff levers looks fine? Or anything else for that matter?

lurkingknight · October 20th, 2013, 22:01

you're talking less than a quarter of a millimeter difference between a cutoff that is flipping high enough to work vs just flipping so it looks like it's working. If you aren't used to looking at a new one vs a worn one, it's hard to tell the difference.

Acid44 · October 20th, 2013, 22:15

@Styrak - I know how it looked new, and how it looks now, just guessing it looks fine, I guess.

With the gears in, spinning them by hand and holding everything in place, the cutoff was stopping them.

Either way, I don't think it's that now. I cut the selector plate so it would run semi only, and it's working in semi now, but there was nothing visibly wrong with the selector plate before, so is it possible something just wasn't seated right and causing it to fire full?

The cutoff lever is so cheap it's a swap it out automatically item.

You can't tell if it's off-spec by eye, you can't tell by rolling the gears by hand, you have to swap, rebuild, and test.

When you say working on semi is that when you test in pieces or when it's fully built up?
