The next step in putting the Rear Sight Back together is to secure the Rear Sight Base and Cover Spring in place. This can be a little tricky.

One way of many to do so is to first center the Rear Sight Base and then lift it until it just barely touches the Cover Spring. Then take a small flat bladed screwdriver and push forward and down on the rear portion of the Spring Cover until it slips into the groove cut for it in the top of the Receiver. A small film of oil on the receiver can help this process a bit.

For clarity, the photo below shows the screwdriver without any protection on it. Use a cleaning patch or some other buffer between the screwdriver and the Cover Spring so as not to scratch the Cover Spring.

Before going any further take the time to grease the splines on the Elevation Knob and the Rear Sight Aperture.

With the base portion of the sight reassembled and the parts greased - complete the final steps.
