I am about to get this gun from a friend of a friend.
It's a tokio mauri. I am not sure what the modele is (I am not yet familiare with riffle to identify this modele)
from what he told me the fps is a little low (playing outside so I would like a 370/380fps). I guess changing the spring would do it. Is there anything I should also change with this modele if I change spring?
I saw some post telling that with TM you might have to also change other parts, but no parts were specify.
I'll appreciate any help you can give me
