The Type 24 also known as the Zhongzheng, Chiang Kai-shek rifle, or Jiang Jieshi Rifle, is a historically significant firearm in China's turbulent early 20th century. It was a Chinese-made reproduction of the German Standardmodell rifle, which laid the foundation for the renowned Karabiner 98k. Named after the Chinese Generalissimo Chiang Kai-shek, this rifle was initially produced in 1935, marked as the Type 24 in accordance with the Republican calendar.

Despite its relatively low initial production due to China's limited industrial capacity, the Chiang Kai-shek rifle served as a primary battle rifle for the Chinese National Revolutionary Army (NRA). Modeled after the Oberndorf Export Mauser, it was a shortened and lightened version of the Gewehr 98, displaying similarities to the Karabiner 98k. The rifle's unique design, including its rear-mounted locking lugs and distinctive bayonet attachment capability, set it apart from other contemporary rifles.

Over time, as China's industrial capabilities in cities like Chongqing and Kunming grew, so did the production of these rifles. They became emblematic of the Generalissimo's National Revolutionary Army, despite an ironic twist—these rifles were also heavily used by the Communists in opposition to Chiang Kai-shek during the Chinese Civil War.

The Chiang Kai-shek rifle's historical significance is further underscored by the claim of Chinese Sergeant Tung Chih Yeh, who boasted of shooting over 100 Imperial Japanese Army soldiers using this very rifle. About 600,000 of these rifles were produced between 1935 and 1949, with roughly 400,000 manufactured during the war.

While it eventually phased out from frontline service in favor of more modern American aid equipment, the Chiang Kai-shek rifle continued to serve the ROC armed forces into the 1970s, particularly in reserve forces. It also remained a prominent ceremonial rifle, still used by the ROC Army for ceremonial and parade purposes to this day.

The Type Chiang Kai-shek rifle's legacy extended beyond China's borders, seeing use in conflicts such as the Korean War and the Vietnam War. It continued to be utilized by various factions within China, including the People's Liberation Army, Red Guard factions during the Cultural Revolution, and local paramilitaries up until 1980.

This rifle's major advantages over its contemporaries included its superior stopping power, rate of fire, and range, owed to the 7.92x57 Mauser cartridge it utilized. Despite firing with more blast and recoil, it offered a significant leap forward in battlefield effectiveness. Additionally, its compatibility with the HY1935 bayonet made it a versatile tool for soldiers on the field. The Chiang Kai-shek rifle stands as a symbol of a pivotal era in Chinese history and a testament to the innovation and adaptability of its armed forces.
