Not to be confused with MAS Tritube, a related weapon.

The MAT Tritube was a French prototype triple-barreled assault rifle designed by Pierre Jampy, Henri Bouix and René Armand in 1972 and produced by the Manufacture Nationale d'Armes de Tulle in prototype form only.

An experimental assault rifle design, the MAT Tritube was an attempt at increasing the rate of fire of an assault rifle.


Designed by Pierre Jampy, Henri Bouix and René Armand,[1] the Tritube was designed in 1972[1] as an attempt to design a small-caliber assault rifle with a high rate of fire.

One prototype was built by the Manufacture Nationale d'Armes de Tulle and it competed against a similar design by the Manufacture d'armes de Saint-Étienne. The design of both weapons proved unsatisfactory and the concept was not developed further.[2]

Design Details[]

The Tritube operated using a lever delayed blowback system.[1] The weapon takes three round plastic clips with three rounds inside them; these are inserted into oversized magazines which hold a number of these plastic clips.[2]


The weapon takes 5.56×45mm NATO ammunition inside square plastic clips.[2]
