Currently I'm running it with:
- PSSM190 thick type spring (modified length)
- Classic Army advanced steel cylinder (with included spring guide)
- Classic Army APS vacuum piston (royal blue, aluminum)
- Stock CA trigger system
- PSG-1 madbull tightbore (cut to length)
- Stock CA hop-up
I guess another question I have is how loud is the stock trigger system compared to the zero trigger systems? Is there a difference? My stock trigger system has been great even under all that stress and the trigger pull isn't bad at all. But if the stock trigger is creating my noise then maybe it's time to purchase a zero trigger. Or maybe it's as quiet as it's going to get and I should just shut up and like it!
