Warning to G&G M14 users........ NOT properly designed for constant semi-auto use!!!!

Background, got a used G&G M14 a few months back to upgrade and set up for semi-auto only (so he could run a 400+fps spring). Fair nuff.

Back then, I noticed the right leaf contact was half split at the angle (note: there are two contact fingers inside most AEGs, each one looks like......... sorry for going cheap on the diagram............. \___ ). Anyways, I saw that, roughed the surfaces up with an emery board, cleaned well and made a nice solder fillet across the bent part to hold it together.

After much usage by the owner, he decided to sell the gun and buy a TM M14. The new owner asked me to reinstall the selective fire parts, and install the stock spring. I'm swapping things around, then notice the contact I had previously seen and 'fixed', had charred more and melted the solder (as if I hadn't even put it there!!!), but worse, what once was a roughly 5mm wide peice of copper like metal (the contact fingers), only has about 1mm left hanging on.

Point being, the contacts (these things again \_____) are made of thinner metal than I've seen in TM and CA guns (actually, the lines you see above are the rough thickness of them, very thin!). When the contact block comes close to the contact 'fingers', an arc happens and chars/eats away at the metal (right where the bend is).

The previous owner I've seen numerous times fire semi auto like it's full, 6-10 BBs per target in a few seconds kinda shooting (not like the 'sniper rifle' he tried to pass it off as). Each time you pull the trigger, the arcing occurs. Looks like the G&G M14 will have a much longer life when used in full auto only, than it will in semi.

Figured I'd mention this, part a heads up and part "Pay attention to this part!". Also, owners of this gun should dig around and find any info on whether there are replacement parts for this contact assembly.

EDIT: Will add this in, he bought a semi-used G&P stock spring from a friend of ours, I think it ended up shooting around 420ish, and he started complaining after a couple games that the grip/motor would get really hot during use. I got it back, did some test firing and such, found the same. Then I cycled it without the stock on my bench, wires, battery and motor got really hot, then the motor started smoking like an idling cigarette!!! And this was with properly shimmed gears!!!!!!!!!!!!!!! I left it sit for 10mins to cool down, the motor was still very warm to the touch after. He bought an EG1000 short motor for it, I installed it, it lasted through a good half dozen games before he sold it (yes, it still runs great now). My point, if you want to run a heavier spring in this rifle, invest in a TM short motor!!!!

This is true. At least this reinforces G&G's reputation though. Lol

My friends Classic Army G36 just had it's trigger mechanism fail due to arking and boy did it ever fail!

The contacts (that look like that \______ ) didn't actually burn too badly, it was the actual plug that the trigger pushed between them to make the contact that failed. There was a crescent moon shape missing off of one side of it from arking and this was a new gun that had only had maybe 5,000 rounds shot through it.

We figured part of the problem was that almost every shot was made on semi-auto but the main culprit seemed to be that during manufacturing one of the 2 contacts ( these buggers \______ ) had been twisted slightly so that when the plug slid in between them it was getting the arks on the it's very top corner instead of all along it's vertical front surface area.

Hope that made sense, I'm pretty bad at explainging things.Just thought I'd add it in as it seemed somewhat related.

Thanks for the info Stalker.

Sheers,
-Dr.

I had a gg m14 max. Hella accurate but i found that eventually the semi auto began to slip into full auto. I ended up selling it not sure if the next owners ever fixed it

Strange. I had one of these for 2 years. Only used it on semi. Traded that m14 a couple weeks ago and the internals were still fine including the contacts. Guess i got lucky.
