FB02 – Euro Rail Base for Bettinsoli Superimposed Express Rifles

12 mm / 60° Euro Rail Interface

The Contessa FB02 Euro Rail Base is a precision-machined fixed mounting base designed specifically for Bettinsoli Superimposed (Over & Under) Express rifles. Engineered around the 12 mm / 60° Euro Rail standard, this base provides a secure and repeatable interface for use with Contessa Euro Rail Quick Release (QD) mounts.

Manufactured by Contessa Alessandro & C., the FB02 installs directly onto the rifle and forms the foundation of Contessa’s modular Euro Rail system. Once fitted, compatible QD mounts can be attached or removed in seconds using Contessa’s proven clamping mechanism—allowing shooters to swap optics on a single rifle or share an optic between compatible rifles without loss of zero.

Constructed from blued steel, the FB02 delivers excellent rigidity, long-term durability, and a traditional finish that complements classic express rifles while meeting modern performance requirements.
