I currently own the Copper John Dead Nuts Pro with the .19 pins. Everthing everyone said above is correct. The new sight cover that is coming out is just like the Butler Creek scope covers people use on their guns except they are not clear. They will retail for about $25 though. I love my Dead nuts pro, Copper john has made a lifelong customer out of me with this one. Everything on it is machined aluminum and stays nice and tight. I would not hesitate to buy another one. And also Copper John's customer service is #1, always very helpful, quick to respond, and listens to their customers advice. Go with the Copper John you won't regret it.
