The M4 is the semiautomatic shotgun: with Benelli patent self-cleaning auto-regulating gas system with rotating locking head. The high-tech nature of its design and development is thanks to Benelli’s experience in the design of semiautomatic shotguns. The M4 was selected by the US armed forces: as its Joint Service Combat Shotgun, after passing all of the stringent acceptance tests for efficiency, reliability, ballistic precision and strength in the worst possible conditions. The M4 is also available with telescopic stock that can be adjusted in 5 positions.
