M7 bayonet

The M7 bayonet is a bayonet that was used by the U.S. military for the M16 rifle, it can also be used with the M4A1 carbine, Steyr AUG and the IMI Galil assault rifles and carbines, and Mossberg combat shotguns. It can be used as a fighting knife and utility tool. It was introduced in 1964, when the M16 entered service during the Vietnam War.

The M7 is based on the older M6 bayonet for the M14 rifle. The most notable differences between the two are the diameter of the muzzle rings, and the locking mechanism. The M7's release mechanism is on the pommel, while the M6 has a spring-loaded lever near the guard that when depressed releases the bayonet. Both models are approximately the same length, have the same black finish, and use the M8A1, or later M10 sheath.

The M7 was partially replaced by the M9 bayonet in Army service, and the Marine Corps replaced it with the OKC-3S bayonet. The Army, Navy, and USAF still use M7s and may do so for years to come.

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

The M7 blade and hilt are very similar to the M4 bayonet with the Korean War era plastic grips for the M1/M2 carbines except that the M7 has a much larger muzzle ring. The M7 has the same two-lever locking mechanism as the M4, that connects to a lug on the M16 barrel. The blade and basic grip for the M7 is similar to the M6 (M14 rifle), M5 (M1 rifle), and M4 (M1/M2 carbine), all derived from the World War II M3 fighting knife.
