I also have a sporting clays gun (Opal Sporting) that I purchased used after posting a similar question on this site. I am extremely pleased with the gun and shoot it very well. Although it was custom built for someone else, it feels like it was fit to me.
The only minor problems that I have had were the triggers were a little heavy (now a crisp 3 - ¼ lbs on each side) and one of the ejector rods was bent somewhere in the past. The gun has great feel and works on a clays course at least as well as a target grade O/U.
I have run at least 3000 rounds through the gun in about 6 months with absolutely no problems. Overall a great gun and I believe they are very well built for the money.
