If you are looking for the inner diameter I have found the stock barrel to be around .691 + a little. Thread size is referred to as a "twist-lock"<----exclusive to AGD.
Several barrel choices can be made here

Hope this helps

barrel size? you can use many different types of barrels, the size (diameter of the barrel) does not matter, just the threads (cocker) or the old twist locks.

barrel size: length- will get you accuracy up to a point...
Diameter- match to paint for accuracy
