Well I took my Bobby Christain Virginia smoothrifle, that i purchased off from this sight. To my first ever smoothbore compition at our local club this weekend. It looks like i have to keep this gun, I hit a 9 out of 10 targets and took first place. Being this was my first smoothbore shoot and never shooting this gun without the rear sight i was very happy. For the shoot I removed the rear sight and plugged the dove tail with a brass plug that is flat with the barrel. I'm not sure the sight will ever go back on. I have to say Bobby builds a great little gun. This 36 inch colerain barrel was jug choked by caywood, and to those that worry about roundball accuracy after it has been jug choked, have no fear.
