It sounds like whatever was done to the forend, would hold the bbls., away from the breech face, as much as the hook/pin will allow, and allow movement every time the gun fires, battering itself worse than ever.
A year or so back I posted on this forum that this is exactly what one of those J-Spring forend latches do & was severely lashed (verbally) for my statement. Happy to see a few agreeing, even if the circumstances are a bit different. The barrels should not be pulled away from the breech with additional pressure placed on the hinge joint.
