GG&G Benelli M2 2-sht Ext Mag Tube

The GG&G Benelli M2 2-shot Extension Mag Tube is a purpose-built capacity upgrade designed for tactical professionals, law enforcement operators, and home defense shooters who demand reliable performance under pressure. This magazine extension adds two additional rounds to your Benelli M2 shotgun, resulting in a total capacity of 2+1 (2 in the magazine and 1 in the chamber) without requiring any permanent modifications to your firearm.

Built by GG&G, Inc.—a manufacturer with deep roots in the tactical community—this extension tube integrates seamlessly with the Benelli M2's proven inertia-driven operating system and magazine assembly, maintaining the shotgun's reliability and cycling characteristics. Installation requires basic firearm maintenance knowledge and familiarity with shotgun takedown procedures—no gunsmithing or permanent alterations needed. The tube is engineered to withstand the stress cycles of tactical use, remaining durable through repeated loading, firing, and unloading cycles.

Operators carrying a Benelli M2 for patrol, tactical breaching, or home defense will find this extension particularly valuable, as the extra ammunition capacity provides a meaningful advantage in real-world engagement sequences. The compact profile keeps overall length manageable while maximizing ammunition reserves, a critical balance in close-quarters and dynamic environments where reload time directly impacts outcome.
