Just found a Hastings 24" barrel for the A5 mag. If i purchase, it would bring the A5 into the realm of a modern turkey gun (well sort of). It would make it more comfortable to carry and the screw in chokes are available including an x-full .675. Briley and Carlson's also make them. It is the C-2 Hastings chokes.
Does anyone have any experience with the Hasting barrels and chokes?
