sorry to hijack this, I take it then I better off not buying a SLY barrel kit for my vanguard demon to replace the stock barrell

well if it comes with more bore sizes then yes replace it, cos it will be more efficient if the bore size is exact

I have to barrels with my demon, .691 and a 689 I think it is

better off getting a barrel kit like the empire sniper kit or something
