Bulgaria adopted the M90 carbines in 189?. These contract weapons were manufactured by the Steyr factory, and were purchased and used by the Bulgarians in 8x50r original caliber.
The bolt is of two-piece design with the bolt handle and bolt body are one piece; mounted within the bolt body is the bolt shaft or bolt cylinder. The
locking lugs are mounted on the head of the bolt cylinder and the bolt cylinder rotates within the bolt body during the locking and unlocking process. This bolt
is used with all the later Austrian straight-pull bolt-action Mannlichers and, since it provides for frontal locking, is considered to be a stronger system
than that of the Models 85, 86, and 88. The magazine system adopted with the M1886 is used in the M1890 carbine and the later rifles.
The receivers were marked with 'OE WG STEYR' and the Bulgarian Lion on the chamber as shown.
The new action reverted to the helically-grooved bolt head system of Mannlicher's first straight-pull action, patented in 1884, as this had proved much stronger than the bar-lock. The M1890 cavalry carbine embodied a much shorter action than its predecessors, allowing the trigger guard to flow straight into the magazine casing and the cocking piece lay almost directly above the trigger.
In 1934 Bulgaria adopted the M30 8x56R Austrian Cartridge, begun manufacturing 8x56R ammunition. Many of these M90 Carbines were rechambered for the
8x56R cartridge, the S-Patrone with the "S" chamber marking. These were referred to as 'Karabina M90 S' or 'Kal. 8mm Mannlicher S'.
