The M4 is the semiautomatic shotgun with Benelli patent self-cleaning, auto-regulating gas system and rotating locking head. Its high-tech design and development stem from Benelli’s experience designing 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 a telescopic stock that can be adjusted in 5 positions.
