AR stands for "Assault Rifle". Many people think it stands for "Automatic Rifle" but that's only for fully automatic variations of it. The select-fire version is the "Assault Rifle" which can be full OR semi-auto. The civilian version of it is the "Assault Weapon", but that's ONLY semi-automatic. The numbers refer to the year it was designed (like the 30-06) or to the caliber in millimeters of the bullet it shoots (like the 45mm caliber).

Now the AR15 is therefore a selectable-firing Assault Rifle that shoots a 223mm bullet from a 15-round clip (actually it's 14-round clip plus one in the pipe, makes for a total of 15 bullets in the chamber). The M-15 is the "Machine-gun" version of the AR-15, hence the "M" instead of the "AR" which can be confused for "Assault rifle" OR "Automatic rifle".

The Military will sometimes use the M-14, but that just means you have to cock the hammer back to load the next round, so it's one less to start with than the AR-15. Guns like the M-1 Grand are bolt-action and so it only shoots one bullet at a time, hence the "1" in M-1. The bullet is much larger in the M-1 too, so that's why it's called the "Grand". If you need to learn more, do what I do and hang around the gunshows. That's where all the experts hang.
