Definition
Uses energy from firing to complete the loading cycle automatically, while firing only one round for each pull of the trigger.
Mainstream development
Semi-automatic rifles reduce the need to operate the bolt manually. Early self-loading rifles appeared in the late 19th and early 20th centuries. The US Army's adoption of the M1 Garand in 1936 is a prominent example of later large-scale use, rather than the invention date of the category. The English term self-loading emphasizes automatic loading and should not invariably be equated with semi-automatic-only fire in actual usage.
China: from early prototypes to the Type 56 semi-automatic rifle
Drawing on items in the Military Museum's collection, the PLA Daily described the Type 56 semi-automatic rifle, copied from the Soviet SKS, and the subsequent process of domestic production. This is one part of the history of China's service equipment, rather than evidence that China had conducted no earlier experiments with self-loading firearms.
This review also found references to Liu Qing'en's early prototypes in Hanyang. Historical accounts call them 自动步枪 (automatic rifles), but their precise dates, testing status, and classification under modern firing-mode terminology still require cross-checking against original archives. They are therefore not treated as an established claim of priority.
Principles and impact
Problems solved
- Reduces the need to operate the bolt manually between shots.
Principles
- Uses energy from firing to complete the loading cycle, with each separate trigger pull firing one round.
Improvements
- Compared with manually operated repeating rifles, the firearm completes the loading cycle itself.
Significance
- Helped drive the adoption of self-loading military rifles in the 20th century.

Not recorded
Events
The US Army adopted the M1 in 1936、China introduced the SKS and developed the Type 56 semi-automatic rifle
Applications
Military rifles、Ceremonial firearms, such as the Type 56 semi-automatic rifle
Limitations
- Automatic loading still depends on reliable feeding; holding the trigger down does not produce continuous fire.
