We attended our first CAS this weekend and my gunsmith brought my new Yellow Boy ('66, slicked up and different sights) to the range so I shot it. The first stage looked into the sun and I immediately noticed the sun reflecting off the brass frame and right into my eye, making it very difficult to aim. This is a new rifle so the frame is still highly polished. Is there a way to age, or dull this thing up so the sun does not reflect of it. Any "coachin'" here would be appreciated.
