I've been told AEG gearbox grease works its way out the barrel for the first thousand (or more) rounds. Soaked bucking seems fairly common.
As I read the AEG operators manuals (radical idea that it is!) I'm not seeing any lubrication required for them. All the moving parts are in the gearbox. My couple-year old KM4 manual says to clean the barrel with silicone lubricant but experts here note this is harmful and I don't use it. But the bucking did get oil soaked. My never-lubricatred RM4 bucking was very oily too. I cleaned it when I put the 6.02mm barrel in it last month. (Once I figured out how to separate the receivers.)
Those of us used to service weapons which rarely can be over-lubricated need to practice restraint with these guns!
When I had the KM4 bucking out for cleaning I tried the GGG (G&G?) bucking but found the KWA works best for me. Order a spare the next time you order parts. A lot easier to fit a new bucking than clean an old swollen one.

Next, do you have a different mag that you can test? Also, how many BB's are you putting into the mag? Because the mag starts off miss feeding and then works after 40-60 rounds It sounds like a mag issue. But, if multiple mags are doing the exact same thing then my mind turns to the feed ramp.
So we can isolate the problem, this is what I want to eliminate until we figure this out:
- Damaged bucking or hop-up unit - Let's reconfirm and move to other potential issues
- Are there any modifications to the gun?
- Have you removed the gearbox from the lower receiver?
- Have the front wires been moved? There is a small clip that retains them near the nozzle, has that been removed or moved?
- Magazine feed issues - Over loading can cause this. Are you using a new speed loader? Also lubing the mag can cause jams - have you opened or lubed these mags?
- Poor ammo - What BB's are you using?
- Feed ramp damaged or misaligned - If it was removed to get to the gearbox then my guess is that it is not properly seated. Also, the feed ramp may have plastic blocking it causing feed issues
