Frequently Asked Questions

What is the Cei Rigotti rifle?

The Cei Rigotti is an early Italian self-loading rifle designed by Amerigo Cei-Rigotti around 1900. It features a unique short-stroke gas piston system and was chambered in calibers like 7.65 Mauser or 6.5 Carcano.

How does the Cei Rigotti's gas system work?

It employs a short-stroke gas piston located in a housing on the receiver. Gas pressure from firing pushes a piston that connects to a tube, which then operates the bolt handle for cycling the action.

What is unique about the Cei Rigotti's bolt operation?

Unlike many contemporary designs, the Cei Rigotti uses a helical groove machined directly into the bolt itself. This internal groove guides the bolt's rotation and cycling, facilitating the action's operation.

Was the Cei Rigotti based on the Carcano rifle?

No, despite being an Italian design, the Cei Rigotti was built from the ground up as a distinct model. While it might share some visual similarities, its internal mechanics and receiver design are unique.
