We show the S&J Hardware Benelli M4 +1 magazine tube and combat charging handle, and a complete installation.

The M4 +1 magazine tube allows the maximum legal limit of the largest shell that the M4 was designed for, 5 - 3" shells. With the ability to ghost load the M4 with a shell on the lifter that means you can get 5 - 3" shells in the magazine, 1 on the lifter, and 1 in the chamber. This allows for greater capacity of shorter shells such as 2-3/4" for 6 in the magazine tube, 1 on the lifter, and 1 in the chamber.

Discussed are also a few FAQ and a quick safety precaution.
