Re: we m4 upgrading

as far as I know the ra-tech npas only offers you the option to turn down the fps and isn't much of an upgrade. The co2 nozzle works for both co2 and green and is a stronger, better option imo. The original barrel and hopup is crap so if you upgrade that, the nozzle and rod (connects nozzle to bolt) then you should be fine.

I've done this, except for the barrel and hopup and mine works great...when it's not double feeding that is.
