Diameter of Alaskan Scope Tubes

[bigskybound]

May seem a silly question, but what is the diameter of Lyman Alaskan tubes? Can't seem to Google that up. Thanks in advance for helping a newbie out.

Right around .880-.005. The Alaskan is a 7/8" scope, of course. If you are looking for rings, you are looking for 7/8". CC

AKA 22mm.
