CAA MC16N AR-15 / M4 Magazine Coupler

The MC16N links two 30-round aluminum AR-15 / M4 magazines and sets their stagger automatically so the spare mag clears the rifle’s ejection port.  A removable pouch-pull loop lets you yank both mags free at once or run the coupler without the loop for a sleeker profile.  Molded from impact-resistant polymer with extra-thick walls, the unit tightens with three steel cross-screws for rock-solid rigidity under recoil.
