I am in need of some help. I am trying to figure out if a Swarovski with a 50mm objective (Z3, Z6, Z8i, or X5) sunshade will fit flush on my Primary Arms GLx. Thread pattern matches based on feedback from Tenebraex. Does anyone have one of these Swarovski scopes with a 50mm objective, and if so can you measure the outside diameter for me in millimeters? Hoping it'll line up flush with my scope. Thanks in advance.
