I have 80 extractors, EDM wire cut from prehardened steel using Cutters dxf. They are ready to use. They come as a package with the spring and plunger. Also included is a firing pin spring. The price is $12 each. Shipping is $5. A set of ten comes to $149. They also come with a drawing another member has made for locations of holes and mill cuts. This is a reliable alternative to the original RG-G design. Very simple and easier to assemble. The springs are from Lee Springs, and are individually priced much lower than the low qty. price. If there is enough interest I may do another run of at least 100. Thanks for looking.
