I already have a sp110 spring in it which shoots 385 with .20's. What would anyone suggest for a little bit better accuracy. A online gaming friend of mine from Canada suggested either a Prometheus tight bore inner barrel. Any other suggestions? pistons etc. I may have posted this in another forum, but I can't remember which one lol.
i would say start with your compression. With that spring you should be shooting just over 400+ so it leads me to believe you have some loss in compression somewhere. Maybe get a cylinder head and piston head and maybe even a nozzle with an o-ring. You'll be shooting more consistently and then you can grab a tight bore, maybe use .25's and I'm sure you'll be really happy with the results.
The gearbox is all stock CA gearset that came with it. What is this nozzle you are talking about? What brand piston and cyl head would you recommend? I go to the AEX in Sac/Citrus Heights off of Antelope Road from Davis as often as I can when I have time.
