Not sure what they do differently, but if they had not tuned his gun for him, and done one sourced by themselves it would have been called a spectre which I treated myself to as a fiftieth present. At first (quite a while) I had a serious love hate relationship with it. Everyone loved it's manners but struggled with consistent accuracy. I tried selling it, but you pay so over the odds of a 95, no one will give you the money invested.
BUT!!!!! it ain't up for sale any longer, I've now really gelled with it and can produce what is for me acceptable accuracy, to the extent I've this week ordered an imp. Won't see it till April, but it will be worth the wait.
Enjoy your new rifle! If Tony worked his stuff on the trigger too it must be very nice to shoot.
