If someone sends a tired '77 to v-Mach* the results should be fantastic but a used pro sport?
This is my issue.
I've got a HW77 and a prosport and I've gone through both of them.
I've fitted new springs and guides and seals etc
Both shoot well (I think) the prosport it's definitely a smoother gun but that doesn't really translate to better accuracy.
Both are accurate.
But a hw77 that shot like a prosport?? That would be cool.
*other tuners are available
