Problem with Magpul PTS Masada

[Escaladeur]

Hello,

I have buy an used Magpul PTS Masada but I have one problem with.

The BBs are not going all the time in chanber (nozzle front). It's take minimum 20 sec in auto mode each time I change mag to work properly.

I have look more seruistly at all of the parts of this massada to know where is the problem, but it's my first time and im not sure. I don't know why, but the nozzle don't go back before forward. Is't normal ?

I can give you some picture or video to help you.

Thanks

PS: sory for my english
