Did all the USMC M40A1 rifle use the Redfield Standard mounts or were there variations inside the corps on types of scope mounts used? I've seen many pictures of the rifles, and some have two piece mounts or 1 piece Picatinney style rails instead of the standard one-piece, however, since so many of these pictures are untitled I'm not sure if these are official USMC rifles all the time.
Anyone have experience with them?
