Paladin601, The funny thing is,the buffer and buffer pilot you show, from my understanding should go in a M1-M1A. But I just got a real clean and shiny West Hurley 1928 in,opened it up and found the buffer and rod you show in your picture! Go figure. Why would anyone change it out that way? Or do you think that's what was laying around at the factory, I guess I would find that hard to believe. By the way I was told the spring in a 1928 should be 69 coils and 11" long. The one they had in mine had 77 coils
