The Kammerlader M1857 was a Norwegian-designed breech-loading rifle that represented an evolution of the earlier Kammerlader rifles introduced in the 1840s. The M1857 incorporated improvements to the breech mechanism, making it more robust and easier to operate. This design featured a pivoting breech block that allowed for faster reloading compared to muzzle-loading weapons, and it fired a 17.5mm Minie-style projectile. The rifle was equipped with a long barrel and a precision rear sight, making it accurate for its time. The Kammerlader design was unique for its sealed chamber system, which helped minimize gas leakage, a common issue in early breech-loading firearms.

Production of the Kammerlader M1857 was carried out at the Kongsberg Arms Factory in Norway, with several thousand units manufactured to equip the Norwegian armed forces. While exact production figures are debated, it is estimated that between 4,000 and 6,000 rifles of this model were produced. The M1857 was primarily issued to infantry units and served alongside other Kammerlader variants during a period when European militaries were transitioning from smoothbore muskets to rifled arms. Although it was advanced for its era, the Kammerlader M1857 was soon outclassed by metallic cartridge rifles, which offered even greater reliability and ease of use.

The Kammerlader M1857 holds a special place in the history of Norwegian firearms, as it reflects the country's early adoption of breech-loading technology. It saw limited combat use, given Norway's relatively peaceful history during this period, but it served as an important stepping stone in military rifle development. Today, surviving examples are prized by collectors and historians for their innovative design and craftsmanship, symbolizing a pivotal era in the evolution of military small arms during the 19th century.
