Hey Everyone
I have a WE M4. The internal upgrades are all RA-tech; npas, cnc hammer, cnc sear and cnc valve locker.
My issue is that part 40 (plastic tube behind valve body) has broken twice on me already. Also, I have noticed that part 39 (valve guide rod wobbles, not sure if this is normal or not) Before I get another part 40, I was hoping if any one knows what may cause this issue of it breaking?
Thanks
