My SWAG math gives me 1.44" scope height, 51mm scope diameter, 16mm barrel and 3.1mm gap. 25.5mm objective/half + 8mm barrel/half + 3.1mm gap = 36.6mm = 1.44" scope height. Tks.Here's an easy way to get real close with that gun, if you have a set of dial calipers or similar measuring device. It requires three measurements and some math. First, measure the outside diameter of that scope's front bell, then measure the diameter of that barrel housing right by the break, and measure the air gap distance between the bell and the spring/piston housing. For the math, add the scope and barrel diameter measurements together and then divide that number in half, then add the air gap number to it. This will get you very close to the centerline.
