Colt (manufacturer of the M16) and Ontario Knife Company made many of the M7 bayonets for the military and continue to make and sell them commercially.

Other manufacturers included Carl Eickhorn [for Colt], Columbus Milpar & Mfg.

The M7 was also manufactured in Canada, West Germany, the Philippines, Singapore, Israel, South Korea, and Australia.

While the United States Army officially replaced the M7 with the M9 bayonet beginning in 1985, and the United States Marine Corps replaced it with the OKC-3S bayonet beginning in 2003, on-hand stocks may continue in service for many years.

There are two variations of this scabbard, both with an olive drab fiberglass body with steel throat.

The scabbard throat flange is stamped "US M8" or "US M8A1" on the flat steel part along with manufacturer initials.
