Happened to me shortly after I got my ROA

It was caused by ramming a ball with the locking cam in the unlocked position - my bad

I was at Bisley so I took it to Fultons. The gunsmith held it in a soft jaw vice (thin end down with the bend just clear of the vice jaw) and gently tapped it straight with a soft faced hammer, little bit at a time and removing from vice to check straightness after each tap. No heat treatment. I could have done it myself.

Has been fine ever since (more than 15 years).

Mine had a much more severe bend than appears in your photo, but not is the same place - mine was bent right on the semi-circular cut out for the cam lock - the pin is very thin there. I suppose that there is a chance it will break but the bend does not look to be very severe so should be OK.

WHATEVER YOU DO, DO NOT STRAIGHTEN IT TOO FAR AS THIS WILL VERY LIKELY CAUSE CRACKING.
