Benelli M4 Magazine Extension

Benelli M4 Magazine Extension increases Benelli M4 Magazine Capacity +2 for USA Residents, and +1 for Canadian Residents (see more info below). CNC Precision made of 4140 Hardened Steel, Ships to USA and Canada. This Benelli M4 Magazine Extension is for those M4 owners who do not wish to perform the tasks needed to swap out their OEM Benelli M4 Magazine full tube, but still desire to increase to full capacity.

It is a simple process to expand your capacity with this extension, and requires no gunsmithing whatsoever.The Rx Arms Benelli M4 magazine extension is the highest quality mag extension you can find.  It is finished in both Black Nitride (for incredible corrosion resistance on the interior), and then custom Cerekote on the exterior to match the OEM Tube.  This is the same treatment that the Rx Arms Benelli M4 Magazine Extension Full Tube gets. The Custom Cerekote colour will create a uniform look on the firearm.  Most other Benelli M4 Magazine Extensions on the market are black, and they do not match the tube, nor the barrel.

Canadian Residents Information:

  • It is the gun owners responsibility in Canada, to ensure that their magazine capacity is compliant with Canadian law.
    • Some customers prefer their gunsmith to plug their tube for them, if you wish to take this option, choose “unplugged”.
