Introduction

The ZfK 55(Zielfernrohr Karabiner 55) is a precision rifle designed and manufactured in Switzerland in the 1950s. Known for its remarkable accuracy and robust design, it is derived from the Stgw 57 assault rifle, but specifically optimized for precision shooting. Intended for the Swiss army’s elite marksmen, the ZfK 55 is today a highly prized collector’s rifle and a symbol of Swiss weapons expertise.

History of the ZfK 55

Development and adoption

In the 1950s, the Swiss army sought to equip its snipers with a semi-automatic precision rifle derived from the Sturmgewehr 57. The ZfK 55 was developed from this platform, incorporating modifications to improve accuracy and shooting stability.

Officially adopted in 1955, it is produced in limited quantities (around 4,150 units), making it a rare and sought-after rifle today. Its use remained limited to specialized units and snipers in the Swiss army, until it was gradually replaced by more modern rifles in the 1980s.
