It has come to my attention that it is hard to get just the ejector hook for a 9mm Colt pattern AR15, and companies who have them available are charging more than I believe is a reasonable price for these parts.
This kit includes a CAD model, dimensions, a jig for literally hand carving one, and a 2 dimensional drawing in a format that can be given to any third party service of your choosing to make an entire sheet of these parts.
