Rifle silhouette is one of the most frustrating, most fulfilling of all shooting sports.... has something to do with the pseudo-science of psychology's well-documented phenomenon of intermittent reinforcement..... The more you see them fly off the rail, the more you want to see them fly off the rail; and the more you see just them sitting there, mocking you, the more you want to see them fly off the rail! And once you see that first one fly, you are irrevocably doomed to a lifetime of trying to make all of them little suckers fly off rails....

My question is if you are looking at the front sight, how do you see them fly off the rail? LOL

My question.... if you shoot with a scope, how can you see a front sight?

That is simple. my rifles don't have front sights.
