Wimberley Arms WA-4 7 Round Mag Tube Extension – Benelli M4 Compatible

Extend the standard 5 round magazine of your WA-4 or Benelli M4 to the 7 rounds it deserves. This starts as round stock steel and is bored and CNC’d to the correct size and then threaded. If worse comes to worse, these should work great as nunchucks if you buy two.
