CAA's new and improved magazine coupler now comes with both small and large removable pouch pulls. The pouch pull automatically sets the height of the magazines, so they don't interfere with the ejection port. The MC16N's robust design with thicker walls provides more resistance to breakage. Based on the proven clamping design, the MC16N now has three adjustment screws for additional strength. The MC16N joins the CAA family of magazine couplers, along with the MCD16 for polymer AR15/M16 30 round magazines and the original MC16 for aluminum 30 round magazine.
