The clamping feedneck has a very nice finish to it. Mine was black polish and had no scratches on it. Its strong and will clamp down your feedneck like you want it to. The grooves allow you to adjust the clamping force comfortably and easily. I was using this with my richet loader which would not fit snuggly even when changing the o-rings on the loaders neck. I bought this and the problem is non existant. Installation is a snap. Un-screw your old feedneck and the screw this one on.
If your looking for a clamping feedneck for your cocker then I would recommend this one. Personally I think it looks better than others.
