I picked up an 1896 .30-.40 Krag at a Gun Show recently. It is no great collector item, as the the top hand guard and sights have been removed. Someone put a Redfield peep sight set up on it that apprears to be in great shape. However, I have never dealt with aperature sights before. Which one is the elevation screw and which is the windage adjustment? Common sense tells me that the top screw is for windage; and the side screw is for elevation. But I wanted to confirm this as I know nothing about peep sight adjustments. Thanks in advance for your feedback.
