I have one on my H&R 20 guage. Neat idea. I haven't had time to take it out yet, it's been friggin cold outside anyways, so I'm not sure how easy they are to use. I know I want to paint the front post orange already though! The sight radius seems long enough when I'm playing with it though. For twenty bucks you'll still have the heatshield. It was one of my first mods to my Mossberg. It's saved my hands a few times.
