Dont waste your time and money. I had a SMK XS20 (HW95 copy) that was tuned by Bonnie and Clyde. It was a super gun, but the amount of work needed to get it to that stage would have cost as much as second hand 95. We are talking work only, not including the price of the gun.....
These guns are truly dire out of the box. Save up a bit more money and get a quality second-hand German gun. It might seem a bit odd, but used guns will shoot a hell of a lot better than new, as the sharpness is rounded off when they are bedded in.
