I got the blue fox for my first gun did some nice upgrades to throw .32 and it’s a very nice gun the upgrades I did was a Begadi mag 5 bucking, zci barrel and a asg m105 spring. Also greased the gears rather than that manufactured max they use horrible stuff. But yea easy simple and effective upgrades if you want to lift heavier BBs. That’s what worked for me some people may say to use maple leaf macrons but I have not had hands on or worked with them on the blue fox I know that’s what worked for me and I also did the upgrades for my cousin who has the red version and both guns are perfect.
