M5 bayonet

The M5 Bayonet was adopted by the U.S. Military in 1953 to replace other bayonets for the U.S. rifle, caliber .30, M1 (Garand). It uses the M8A1 scabbard.

During the Korean War, the M1 bayonet and M1905 bayonet which mount to the M1, were proven difficult to remove with gloves on. As a result the U.S. M5 Garand bayonet was designed and issued in 1953. This was a total redesign and looks nothing like the original M1905 or M1 bayonets for the M1 Garand. The M5 is the only U.S. bayonet without a barrel mount ring on the crossguard, making it look more like a fighting knife than a bayonet.

The M5 bayonet has a 6¾ inch blade, and overall length is 11½ inches. Weight is 11½ ounces. The blade has one side sharpened for its full length and three inches of the other side are sharpened. There is a relatively large push button release to deal with removal while wearing gloves.

The stud on the bayonet crossguard fits the gas cylinder lock screw under the M1 barrel. Locking grooves attach to the bayonet lug on the rifle. The M5 fits only the M1 and does not interchange with any other firearms.

There were three different patterns made: M5, M5-1 and M5A1.

The grips are checkered black molded plastic and all metal parts are a dark gray parkerized finish. There are no markings on the blade. The manufacturer name or initials and "US M5" (or other model) will be found stamped under the cross guard. Many M5 family bayonets were made in Korea after the Korean War and these will have "K" stamped in place of the "US". Manufacturers included Aerial Cutlery, Jones & Dickinson Tool, Imperial Knife, Utica Cutlery, and Columbus Milpar & Mfg. The M5A1 was manufactured during the 1960s and was the last bayonet made for the M1 Garand.

There are two variations of this scabbard, both with an olive drab fiberglass body with steel throat. The early version, designated M8, has only a belt loop, no hook. The M8A1 retains the general look and can be slipped over a belt, but also has the M1910 bent wire hook available. The model is stamped "US M8" or "US M8A1" on the flat steel part along with manufacturer initials. This sheath is correct for all post-war US bayonets including the M4, M5, M6, and M7. It was also used with the M3 fighting knife.
