I have something you might be interested in. Maybe 10 + years ago, I bought a top cover that came with a G-3 sight welded on the rear portion. I believe, but I am not certain, it was from Red Star, and it was a commercial product, not a Bubba special. If you are interested, I can take a photo, and e-mail it to you. I am looking for $50. for the set-up. Thanks.
