I happen to come across a Springfield Armory White Feather /Carlos Hathcock M-25 (M-14 on Steroids) It's mine now. The previous owner didn't have any manuals or anything on this rifle when I bought it. It is in excellent conditions. I got a hold of Springfield Armory for a manual and they said they didn't have any and all they sent me was the typical M-14 manual. I started to break it down for a detailed inspection but stopped. I stopped because when I went to remove the trigger housing group it seem harder then usual to breakdown. So I didn't want to force it. Any help would be appreciated from someone who may own one like mine. I want to make sure before I go any further. Please and Thank You.
