The Mannlicher M1895 (German: Infanterie Repetier-Gewehr M.95, Hungarian: Gyalogsági Ismétlő Puska M95; "Infantry Repeating-Rifle M95") is a bolt-action rifle, designed by Ferdinand Ritter von Mannlicher that used a refined version of his revolutionary straight-pull action bolt, much like the Mannlicher M1890 carbine. It was nicknamed the Ruck-Zu(rü)ck (German slang for "back and forth") by Austrian troops and "Ta-Pum" by Italian troops who even wrote a song about it during The Great War.
The M1895 is unusual in employing a straight-pull bolt action, as opposed to the more common rotating bolt-handle of other rifles. It consequently renowned for combining a high rate of fire (around 30–35 rounds per minute) with reliability and sturdiness, although this requires decent care and maintenance with an extractor that is vulnerable to breakage due to a lack of primary extraction.
Originally they were chambered for the round-nosed 8×50mmR cartridge, but almost all were rechambered to accept the more powerful spitzer 8×56mmR cartridge in the 1930s.
