Thanks for getting back with me. I need to get these dies at least to have. I have always been a M1 Carbine fan and have owned a couple through the years. I also always wanted one in 5.7mm, so when IAI began to produce them, I made sure that I bought one while the limited supply lasted. I don't know how many of these 5.7mm Carbines were produced by them, but I don't think that there were very many.
