Mine worked fine, was butt ugly. I had one on a Mossberg built Revelation M310. Sold the barrel to a guy at work after buying a new 28" Mossberg vent rib barrel with screw in chokes. I traded a guy out of the gun, wanted it for waterfowl when steel shot got mandated and I had to retire my double, which wasn't steel shot compatible. I had doubts that the C lect choke would work long with steel, either, thus the conversion. The barrel cost me 100 bucks with a modified choke tube included.
