hr-ejector-mod: "Whatever your reason, changing the auto ejector to extractor is a very simple job. Begin by removing the fore end screw, and the fore end. Remove the barrel from the receiver. Now examine the under lug. You will note the ejector, the ejector catch, and three roll pins. The rear most roll pin should be drifted out ( either direction ) until the ejector catch is free. I prefer to leave this pin retained in the off side of the under lug. In this way it won’t get lost and is started, ready to drive back in. If you now pull the punch out, the ejector catch will drop downward and the ejector will move outward. If the ejector does not seem to be free, just pull down a little on the end of the ejector catch. Figure 1. shows the parts I have mentioned as well as a second ejector that has been ground down. Modification of the ejector required about 5 minutes with the use of a common “Moto Tool”. Refer to the drawing in figure 2., to see what metal needs to be removed."
