Nordic Components
Clamp-on magazine extension that adds 2 rounds to the Benelli M4, extending capacity from 5+1 to 7+1.
The Nordic Components +2 magazine extension clamps onto the existing Benelli M4 factory magazine tube to add 2 rounds of capacity, bringing the total from 5+1 to 7+1. Unlike full tube replacements, the Nordic extension preserves the factory tube and simply extends beyond it with an aluminum housing and additional spring length. Installation requires no permanent modification and can be reversed. The clamp-on design makes it the easiest and most affordable way to max out M4 tube capacity. Nordic Components is a well-established name in shotgun extensions across multiple platforms, and their M4-specific model maintains the reliability and cycling characteristics the Benelli is known for.
