Falcon...The gun you had is in the minority. I've owned a few and shot some more, and there aren't many that have both barrels shooting at the same point of aim. I had a .223/12 that had impact differences of nearly 8" at 50 yds. How in the world can a person be asked to spend $500+ on a gun like this?
Some that had the scope mount that hooked on one side were a joke. You could put a small amount of pressure on the scope and it would move 1/4".
The older ones were OK at best as far as craftsmanship goes...IMO the newer ones were even worse.
