Does anyone know the inside diameter of a 13 inch troy alpha rail? I have a project in mind but need to know the ID to see if that rail will work. Thanks much.

1.385"

If you add any rails the ID will be reduced due to to the bar that the rails thread onto.

ETA: Mine has the front sight though I don't think that makes a difference.
