I just put a set of Williams Firesights fiber optic sights on my 17L. The front sight is about .160" tall. I'm hitting 6+ inches high at 25 yards. I know I need a taller front sight. I see that Dawson and Warren Tactical list many different heights of fiber optic front sights. Does anyone have any suggestions as to what height front sight I should try on my 17L ? Thanks.
