I have both 30 and 50 round Spectre mags. I am not ready to sell, them as I want to keep the 30 round ones and I am unsure if the 50 round mags function correctly. I know one does not. However, it sound like you might want to just scan them for a 3d printer. I am going to be unavailable for the next few days, but go ahead a send me an e-mail telling me what you want to do, buy them or scan them. I will work with you on it.
