my two cents

Make sure you are shimming using the gearbox shell, gears and bushings only for initial test fitting.

test fit the shell halves by holding them together in your hand and use a small push device to test for side to side lateral slop in the gears by pushing back and forth on the gear shafts individually.

add or remove shims as needed, keeping the spacing of the gears from each other, also a priority. You don't want a gear pushed up on another gear. gears work with gears, not gear bodies trying to turn against one another.

You also want to make sure the tappet plate can move freely once the two shell halves are together. or the sector gear isn't shimmed too high and its pushing on the tappet plate. This will torque the tappet away from the delayer and can lead to tappet failure. Everything is happier when it moves in a straight plane of motion for optimum engagement.

for the final test screw it together and check for spin and any lateral movement including free tappet movement.

next, check the sector gear engagement point on the piston, does it need it's aoe corrected? is the piston seated properly in the guides during reassembly or is the piston jumping out of the guides during operation? It might need a new piston.

Does this aeg use a ball bearing spring guide or piston head, this will also smooth things out.

if free movement of the gears, sector engagement is good then reassemble, check the tappet plate is moving freely, plug in the battery, test once, adjust motor height if needed, carefully, see if it smooths things out and cycles better.

this episode of: will it break if i swing it at a tree

sometimes there's a saying, "Don't believe the hype" Sometimes a polished up turd is still just a turd.

To be honest my friend, most of us in the airsoft community have been where you are right now and the frustrations are real.

My advice is use it as a learning experience, be patient and take a look at the gearbox, apply some if not all of what i've suggested and see if it works out.

patience is a virtue in both airsoft and life.

I won't send you a bill for this first session of airsoft anxiety counselling 101

Believe me, (most) things can be fixed and most things cannot. It is no different in the airsoft world and these things do need tinkering with to make a good gun a great gun or a shit gun a parts in a bucket gun. Parts in a bucket is only after you've given it a good go with applicable knowledge for the task.

The lord hates a quitter but after everything has been tried no amount of voodoo magic can resurrect certain things and cost effectiveness / availability of parts become a factor.

If you need some help let me know, i will do my best to assist ok

I feel like you wrote all that just to call dibs when he quits and wants to get all of his broken stuff.

Everything you wrote is nothing new to me but thank you very for at least trying to help. I didn't shim the gearbox simply because I wanted to use the gun stock for a bit as I usually do before shimming/upgrading. I've been playing airsoft for 5 years and had experience with about 8 guns now. A Cyma AK which still rock solid even after 3 years and the rust, I did upgrade it quite a bit. My LCT is a year and a half old, still works fine. I also bought a E&C M27 awhile ago, maybe 6-7 months old now, works fine too, just had to shim it. Krytac is the first letting me down, 3 months old and just a few games played with.

I think it like buying a reliable brand of automobile. One out of a thousand is a lemon.
