This component is a crucial part of the Uberti 1873 Cattleman revolver, a replica of the iconic Colt Single Action Army. It serves as the axle for the cylinder, allowing it to rotate and align each chamber with the barrel for firing. This part is typically a hardened steel rod, precisely machined for a snug fit within the frame and cylinder.
Proper function of this essential element is paramount for safe and reliable operation of the revolver. A well-maintained and correctly fitted example ensures smooth cylinder rotation, consistent alignment with the barrel, and prevents binding or seizing. Historical context highlights the importance of this design in the evolution of repeating firearms, enabling faster reloading and increased firepower in the late 19th century. Its continued use in modern replicas reflects the enduring practicality and elegance of the original design.
