Ok cool I think I'll do it tomorrow as it too hot to play this weekend 😅. What sort of FPS should I expect running it stock with .28g? I know FPS isn't the being all and end all out but if it's fairly low I'd look into getting a spring next and people have said the stock isn't very good anyway.
I'd probably look to change the spring as well, which would you recommend? I have a spenca arms m90 already.
I can't find a 215mm inner barrel in stock and don't want to make it longer as it's small size is the main reason I got it
