Take the steel ring and put it below the spring (base of the receiver). This isn't chambered for the 2 9/16 is it?
I would say that it is almost impossible to get an A5 to double feed unless parts are broken, even then the carrier will be up and the shells will come out of the loading port.
The part that unlocks the bolt from the barrel is unlocked by the link on the cam , when it moves back it the link changes angle and moves the cam and unlocks the barrel.
I am mobile here but when I get home I can give you instructions on how to remove the bolt if you want. I have pictures of the parts too.
