M4 GBB Gas Route Bucking question
So with some more time now, I've been able to get back to working on my wonky M4 GBB. I've narrowed it down, and I think it's the gas route bucking that is causing my bolt jamming issues. I think it's just too tight, so when I fire the nozzle gets jammed on the bucking. My question is can I shave the bucking to bring it down a bit, or is there some after market buckings that are recommended? Any help would be appreciated.
Pictures will be good. Mind you, the nozzle should be going -all the way into- the bucking. Seems your nozzle is protruding in too far.
Here are some pics, sorry for the delay and thanks for the help Q.

Also made a quick video of test firing.

Ah with the pix you mean the magazine gas buck routing? For the moment, I thought you meant the hop up bucking. You got to get the right sized gas route bucking. That's why there are different sizes :-
