US Army M-6 fighting Knife -
The M6 Bayonet is a bayonet used by the U.S. military for the M14 rifle. It was introduced in 1957,
at the same time as the rifle itself. It is the only type of bayonet made for the M14, and the
only other rifle it fits is the civilian version of the M14, the M1A.
Like its predecessor, the M5 bayonet for the M1 Garand rifle, the M6 was intended to serve additional
roles as a combat knife and utility knife. The basic blade design was like the M4, M5, and later M7
bayonets, based on the World War II designed M3 Trench Knife.
The M6 was replaced by the M7 bayonet after the Vietnam War, when the M16 Rifle was adopted by both
the United States Army and Marine Corps as the standard service rifle.
The handle of the bayonet is made of hard plastic. With a checkered pattern for ease of gripping.
Two rivets hold the handle in place. A lever is placed near the crossguard. It is used
to disengage the knife from the rifle.
