Thanks Panman. The gasket and ring are fine. One thing I did notice on the picture on Wantsall's website is that the heatshield that is in thier pic fits tightly around the front sight. The heat shield that they sent me has a large rectangular cutout that gives the heatshield about a third of an inch rotation side to side which is enough for it to get caught under the pump on either the left or right side depending on which way it feels like roatating -- annoying. I think I will see if I can get them to replace the one they sent me with the one advertised on thier website.
