The M24/29 is a light support weapon of French origin. It was developed to replace the troublesome M1915 Chauchat. The M24/29 proved to be a succesful design and is known for its quality. In French service it was designated the Fusil-mitrailleur modèle 1924 modifié 1929 or FM 24/29 for short.

The M24/29 is based on the Czech ZB-30 and started out as the M1924 chambered in the proprietary 7.5x57mm round. When the 7.5x54mm round was standardized in 1929 the design was altered and the new weapon was designated M24/29. The M24/29 is gas operated and features two triggers, one for semi-automatic fire and the other for automatic fire. The magazines are inserted at the top, resulting in the sights to be offset to the left.

The M24/29 fires the French 7.5x54mm round from a 25 round magazine. The two triggers allow for semi-automatic fire and automatic fire at 450 to 550 rpm. The maximum range against area targets is 800 meters.

The M24/29 was the standard automatic weapon in French service when World War 2 started. In the 1960's it was replaced by the AAT-52, but remained in use with the gendarmerie until the year 2000. In the 1960's it was widely exported to the ex-French colonies and often remained in active use well into the 1980's. Nowadays the M24/29 is considered obsolete.
