I had my fjs m4 tested and now the problem is that the gun won’t feed well
I’ve opened and cleaned the magazine , No sign of problem there
Opened the gun also , No sign of problem there , also ( idk why )
I use a combination of hardend , blueish and green gel balls ( green one’s also hardened ) but it has a problem and this problem annoys me , any help appreciated
Is it the same with different mags or are you only using the one?
You can check to see if a msg is feeding by using a 9v battery on the terminals, from memory the + was typically the front terminal, it’s also easier if you have one of those battery housings with wires stretched.
If it’s not the mag and it isn’t cycling when in the blaster then a wire has broken leading to the mag terminals somewhere.

Mag prime works , Gun works but the mag prime has some cycling delays , the gun shoots but sometimes gels don’t come out ontime and dry fires
It may be a mag problem and i have only this magazine
Dunno , maybe but the motors healthy and new . i recieved the blaster brand new today
I have a very strong suspicion your feeding issues are caused by a mix of oversize poor quality gels.
Ditch the mix, grow a batch of quality gels that are roughly the same size and see how it feeds. I’d avoid ultra hard gels at this point.
Mixes of less than average quality gels are really only good for grenades. 
Sadly that doesn’t guarantee there isn’t a possible fault out of the factory. These things are regularly shipped from China with issues that prevent them from working.
Welcome to gel blasters.
