In fairness I did ask about what you get from SFS various stages of tune but when it was pointed out there is no buttoning done on any of Tony's tunes I asked who from the BBS could do it so I could just go with a vmach kit after the buttoning had been done.
No he wasn't........He just didn't read the thread properly, my apologies.
I would not by a potato gun from them
I bought a hw 45 from them -- it was not shooting right the trigger seemed way to heavy so I went to ajust it --the grubscrew was missing
even my mate checked it for me and it was gone
I took it back and told them tony took it back to workshop came back and asked what I was talking about its there plain to see - yes it was but he lied he fitted one ---- why lie --- I was just happy it was sorted
