Frequently Asked Questions

What are the three main types of Chassepot-Gras cavalry carbines?

The three types are distinguished by their receiver markings: 'Manufacture Imperiale' (Second Empire), 'St. Etienne' script (transition period circa 1871-1872), and 'Manufacture d'Armes' (Third Republic, post-1873). Each type reflects a different era of French arms production.

How can I identify a Chassepot-Gras carbine conversion?

Look for the '-74' designation following the '1866' model number on the receiver or barrel. This indicates the firearm was converted from the original Chassepot paper cartridge system to fire the 11mm Gras metallic cartridge.

What is the significance of the 'M 80' marking on a Chassepot-Gras carbine?

The 'M 80' marking signifies a safety upgrade implemented around 1880. It denotes the addition of a gas relief cutout in the receiver, designed to vent propellant gases away from the shooter in case of a cartridge failure.

What are the typical physical characteristics of Chassepot-Gras cavalry carbines?

These carbines are generally shorter and lighter than infantry rifles, featuring a bolt-action, single-shot mechanism. They commonly have brass furniture, including two barrel bands and a nose cap, and a barrel length of approximately 700mm.
