Berthier Carbine with Chauchat Magazine
This video details a rare modification of a Berthier cavalry carbine to accept an 18-20 round Chauchat (CSRG) magazine. Expert Ian McCollum explains the historical context for WWI aircraft crews and survival scenarios. The modification involved significant structural changes, including the stock, magazine well, trigger guard, and receiver, to integrate the single-stack semi-circular magazine. Due to its complexity and rarity, only four such examples are known to exist.
