BEST GAS AND NOZZLE UPGRADE ADVICE FOR WE M4A1 NEEDED PLZ

[SethB]

As mentioned in subject need advice on my WE M4A1 TAN GBBR. The one with the annoying plastic feeding nozzle that break very easy.

I've had the rifle less then a month and burned through two plastic nozzles already and i be damed if i am buying a new one for every game. 

Any advice on this and do i trust WE is just saying buy only there own brand gas and BBs to make money out of me (i hear pro pain is an option is this true)

do i consider buying the RA tech metal nozzle with using the stock spring to bring the FPS to a more consistent output.

so far i used the blaster 0.2 bbs and abbey vortex gas.
