some test firing of my g36 before game season starts... and this happened.







fired about 500 rounds full speed in all... probably another 1000 rounds at half speed.

CA 7mm bearings. Will be ordering up some bushings now.

and maybe a new set of gears. The SHS 13:1s are still in good shape... the spur on the fat side is a bit polished for obvious reasons... it ate away at the gearbox more than the gear. Some grinding occurred at the extreme sides of the teeth... so my spur and sector are a fraction more helical than straight cut now.

I didn't even lay into the trigger when it went... just pulled it sounded like the motor height came undone... I pulled once more to verify, no more cycle. And that was that. Pretty obvious what happened once the gearbox came out.

So I know this is mostly dedicated to an AEG gun doc but....

I was sent an M4 to look after. Took it apart.

....and look at what I found!!!



This was a build up of "lube gunk". The owner complained that it no longer fired and would vent gas on the first pull of the trigger.

I surmise that because of the cold gas venting from the magazine, it completely froze the gunk up and made it super hard.....

This is what happens when you don't take care of business like you should, fellahs.

The gunk was soooooo thick and hard that it didn't return the bolt all the way such that the loading muzzle and gas route packing on the magazine didn't line up. Ergo, all the vented gas.



Look at how thick the fucker is!!!
That's one helluva lot of lube....
I had to mildly heat the muzzle up just to get it off because it was soooo compacted in there good and tight that it refused to be scraped off.

Frack!!!!!

This is the side effects:



notice how much of the bolt was still sticking into the buffer tube. This prevented me from properly taking the upper and lower receiver apart. I had to undo the front pin and completely separate the two halves just to get the damn bolt out....

I don't know what the hell kind of lube this guy was using but...WTFBBQ!?

Also, why the hell would this be all over the loading muzzle anyways!???

Anyways, problem solved. Gimmie my $50 fee....
...or a carton of Belmonts. Large Kings.

I'm surprised a couple of strikes of the F/A wouldn't get it to seat forward enough to open up.

The gunk hardened so much. It felt like hard rubber after.
It was "packed" in there when the muzzle slams into the hop up chamber. I guess repetition made it so well packed that the bolt no longer returned to battery.

That was as far as the bolt went...

And that's why you don't use bearings.

I have a TM G36C that like to do the same thing till I changed to steel bushings...

Would some solvent work?

I was given a G&G SCAR-L and a long outer barrel to replace the stock short one.
Ok fine, that's a normal request.

Open up the gun and take the barrel out of packaging.....STAR type SCAR barrel.

Sigh.

Yay, I got another gun that wasn't put together very well. Now I have to clean up the mess.

Cracked and missing piece from the switch assembly.


Two piece contacts sandwiched and tried soldering them together.


Mismatched contacts that isn't even making contact.


And the soldering job. OMG!!!





The wiring was also shredded but I don't want to post all the issues with this gun. And to whoever did this job, I'm not bashing you, but please don't do this or anything that you don't know how to.
