Finally got a chance to go out and try my new lower front sight today. Only got to shoot at 100 yards but the results were great. I was using the rear Williams peep with the new lower front sight that T/C had sent me free. First 3 shots were about a 4 inch group about 4 inches high! Guess the new sight is a success! Lowered the rear peep and my next group was about 3 inches about 1 inch high. Since my self imposed limit on range for this setup is 100 yards, I would call that very good.
