Hi Jay, been awhile! No, my RBL is just clicking right along. I did slick up the chambers and it is now an extractor gun. Past that it serves its intended purpose killing phez and the occasional grouse and very occasionally these days a Hun. No problems. My largest dissatisfaction is the engraving. less, or none would be more. Mine has great wood for the 2X.
I will add that it was a good deal at 3K. I wouldn't pay what CSMC wants now. Lots of other options.
