I agree with everything that Butcha said. I have owned one since they came out and have never had a problem with it. We sank a boat once in 4 ft of water with my 870 at the bottom of the channel, retreived it(boat too), field stripped it, got rid of the loon goo and kept on hunting with it the rest of the day. Had a Wingmaster before that...never any trouble. You can`t go wrong with one.
