I guess 20 years ago, I bought the first Citori Plus O/U to come to a large local distributor. It was a non-ported 32" gun and the rib rattled and jingled when the gun was closed. I wrote to Browning about it and was told it did that because it was adjustable. They also said that the recoil reduction device leaked lubricant because it required no lubrication and that it made a clicking noise because it absorbed recoil.
It went to a new owner soon afterward. A product is only as good as the service behind it.
