I want to build a precision rifle for my son so that he can shoot with me when I take the Vudoo out. I have a CZ 455 that I'm going to mount in a MDT chassis, and I want to mount a SWFA SS 10X42 scope on it. What I don't know is which ring height is appropriate for this mount. I'm going to get a set of 11 mm dovetail mounts for the scope as I don't want to go through the expense of adding a rail. Also, I've heard that the MDT chassis, when used with an AR buttstock, places the shooter's eye pretty low, so I'm concerned that too tall a ring will make it hard for my son to get a proper cheek weld. I suppose that I could always go with an XLR stock, but that will add another $225.00 to the rifle in addition to the chassis. Quite frankly, I'm broke after purchasing the Vudoo lol. If anyone out there knows the answer to my question, I'd appreciate the guidance. Thank you.
