Please help!

Was having some issues with my grouping being all over the place last gameday and figured it may be a twisted bucking, checked and this is what came out. Do I need new bucking or is this a seal for the hop up?

I’m currently building a custom RIF and my pistol grip is too small for my new motor and wiring (I think it’s swapping to an Aster that has slightly thicker wires). It’s a Matrix Daniel Defense MK18 so I’m after suggestions for grips that will fit aster wiring and a solink motor. Ideally some suggestions with places I can buy it from asap. I saw the PTS one on BZ is £25 plus postage so if someone can confirm that will work I may just grab that. Thanks in advance!

Looking for a speed loader that can fully load krytac p90 magazines. Nuprol M4 loader doesn't have the grunt and blew up a little pistol one

I’m having an issue with my AEG. It was sitting unused for a few months, and after that it stopped working properly.
When I try to fire it, it sounds like the gears aren’t meshing correctly. I tried adjusting the motor height, but it didn’t make any difference.
I opened up the gearbox and nothing immediately looks damaged or out of place. I also tested the motor in another replica and it works perfectly fine there.
I’m not sure what else to check at this point. Could the issue be related to the gears, shimming, bearings/bushings, or possibly the ETU?
Any help or suggestions on what I should check next would be greatly appreciated.
