Jgg63 klonk

[Dannn]

After a few second burst on full auto when I release the trigger there's a klonk.... I know it could be anything but any ideas, could it be the piston just returning ?

Define klonk. Preferably with a video.

 

The piston returning after releasing the trigger is a small "clack". If the anti-reversal latch is missing then it's a longer sound as the gears move the motor.

I'll do a video tomorrow, bestvnot give it fully auto at this time !

The clonk after auto it's hard to make out on video

nothing to worry about and relatively normal.

 

Not entirely sure what causes it (and I'm not going to try an work it out in this heat), but common on a lot of lower-low/mid end AEGs

if its new it may just need wearing in

[Samurai]

Everything is fine.

 

That sound is because your bevel gear has 4 teeth that the anti reversal latch can catch into and when it starts to reverse, it can move a bit until it catches.

 

If you want to get rid of it, there are bevel gears with 6 or more of those teeth.
