Precision Rifle Barrels Regarding Airsoft Precision/tightbore Barrels And Range/accuracy Improvements?

Regarding airsoft precision/tightbore barrels and range/accuracy improvements? - precision rifle barrels

I have a gun Socom16 G & G already has a 6.04mm contain tightbore him. I wonder whether a 6.03mm tightbore not significantly affect the range and accuracy. Someone there are further recommendations on how to extract a greater range and accuracy of the weapon? A final question is, if I were in a M120 spring, which other parts should I replace to make sure that spending the spring do not break my gun? Thanks
