Corps replaced it with the OKC-3S bayonet. The Army, Navy, and USAF still use M7s and may do so for years to come. M8 and M8A1 Scabbard There are two variations of this scabbard, both with an olive drab fiberglass body with steel throat. The early version M8 scabbard only a had a belt loop and lacked the double hook that earlier bayonet scabbards had for attaching to load carrying equipment such as the M1910 Haversack. The improved M8A1 scabbard manufactured later in WW II has the M1910 bent wire hook. The scabbard throat flange is stamped "US M8" or "US M8A1" on the flat steel part along with manufacturer initials. Some M8 scabbards were later modified by adding the M1910 hook. Later M8A1 scabbards were manufactured with a modified extended tab on the web hanger to provide more clearance for the M5 bayonet which rubbed against the wider bayonet handle. 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.
