No, those are for cranking up the tail like a windage elevation sight.

It's all very well to run around saying regulation is bad, get the government off our backs, etc. Of course our lives are regulated. When you come to a stop sign, you stop; if you want to go fishing, you get a license; if you want to shoot ducks, you can shoot only three ducks. The alternative is dead bodies at the intersection, no fish, and no ducks. OK?
