Re: Leupold 3.5x10 with M2 knobs question
Tell him to take the turret off the scope. 3 set screws on the turret, loosen em and lift the turret up. You can see on the scope body a metal 'block' where it will hit the zero stop, looking at the underside of the turret there should be a little detent in the shape of a ball bearing. If either of the 2 are missing, then it is not a zero-stop model.
