Sorry ,I have to disagree . The M14 ejector is NOT the same as the ejector on the M1 Garand .The M14 ejector has 3 bevels on the face as opposed to 2 on the Garand .The neck where the spring fits is also different M14 is .075 and the Garand is about .060. It might work in a pinch, but it will be difficult to keep the M14 spring which is larger to fit snug on a ejector with a smaller neck .
I am not saying it will not work ,I have never tried it . I am just saying that they are not the "Same".
I apoligize in advance if I stepped on any toes or offended anyone ,that was not my intent .
