How do you install ejector spring in a jc Higgins model 20 12gauge shotgun?

Answer 1

There is a hidden groove on the bottom of the ejector spring area. While initially it seems as though you should mount the spring with the half moon facing up to match the cutout in the gun you actually put the half moon piece down in the groove on the bottom which holds the spring in place and allows it to sit flush inside the gun save the ejector portion on the end.
