First project gun. Need some advice.

[BlacksunshineGAAS]

Lipoly- Yep thats the kit I am referring to. They have a very high failure rate. Evike was flooded with returns of these. The issue is really a QC one more then anything else. I've heard stories of people having them and they perform great. But then many stories and personal exp that many are simply garbage out of the box. Its very hit or miss. I'd hate to see this guy on his first go wind up realizing halfway in his is one of those lemons that winds up needing a while GB replacement. internals can add up quick and sometimes its better to just get the whole shebang then mess with what you have.

YMMV.

At any rate just from the pics it looks the parts needed are cylinder head,airnozzle and tappet plate AND SPRING. Everything else looks ok for the time being. While your at it I'd also say get a good spring guide with bearings.

Good luck I hope your's isn't a total loss like the ones I've had the "pleasure" of working on.

dbl post.. wtf. weird..

I hope it turns out to be a good rifle too. I think it will be ok. You remarked about the tappet plate - what did you see that was wrong about it?

AndyC, look to see if the gears are shimmed properly as that was the problem in the Matrix Challenge Kit I worked on. I don’t know if the Owner took the shims out or the gun didn’t come with any shims but it didn’t have a single shim on any of the gears, the spur gear was destroyed because of it and the bevel gear was grinding on the top half of the gearbox.
The gun was used for about 6 months with ~80,000 rounds. I was asked to fix the air nozzle (had a small chip in the front), but when I opened the gearbox up I for the gears stripped. These issues aside, I thought the gun was pretty stable and if it hadn’t been for the bad shimming I thought the AEG was somewhat nice.
Pictures:
Each Tooth pick points to a broken tooth on the gear.

OK, I removed the three gears and each has a shim on the bottom. The gears are not knicked, worn too badly or marred in any way nor is the GB itself. I did notice a lack of grease though. Just a smidge here and there and all black-ish colored.

If there is very little grease, you may as well buy some white lithium grease (the same stuff Nec mentioned earlier), and clean out the black gunk.

It really does help keep your gun much quieter, and in the long run, healthier.

Opps sorry I missed the pic where you actually had one. they are kinda cheap tho. that's really why I suggest swapping it. replace it before it breaks kinda idea. I would just check it real well for stress marks and cracks. With the air nozzle having been destroyed the way it is I'd be concerned the tappet took some damage as well. That may lead to poor feeding.

[AndyC]

OK. I checked the Tappet Plate. It's in decent shape, fairly rigid and no cracks or other damage. I am also assuming that from the info on Evike.com, this is basically a JG aeg or JG compatible as most of the internal plastics are red in color just like JG oem seem to be.

The Matrix challange kit is a AIM TOP AEG rebranded (did you miss the pictures above?) so all the Parts are AIM TOP not JG.

BlacksunshineGAAS, I don't recall AndyC saying anything about the air nozzle being broken so there for I would asume his tappet plate would be fine. It was the Cylinder head that broke unless I skipped over something.

[AndyC]

AIM TOP. Got it. Yes, the air nozzle wasn't bad and not mentioned. I replaced it just for gp.

Not sure how much of the listed 'included' parts I have though.....

[BlacksunshineGAAS]

NEC (sorry for some reason I thought your screen name was Lipoly)- I didn't notice a nozzle in his pics so I assumed that he didn't have one to go with the GB. I just saw the hole in the middle of the cylinder head and assumed that there was an incident that caused that port to be gone. not knowing the history of it I assume that all the parts not pictured are either gone/not included. Maybe it was me assuming how exactly it broke and what could have taken damage.
