Barrel lenght

Hi,


Have my Well l96 mb01.
Setup:
AA Hop up
ML Macaron 70
AP Cilynder
AP red cilynder inners
AP M180 spring (610fps with 0.2. Field limits 650fps)
AP trigger
Prometheus 509mm 6.03 barrel (Cylinder/Barrel ratio 2.23:1)

Question:Is that barrel lenght for my setup is fine? Because i find, that many people use between 430-470mm long barrels. How shorter barrel can effect shooting distance/accuracy? (Now it shoot accuracy 80m~. Using 0.48 BLS bbs.).

Or maybe there is any other inners which would make my gun even better?
