This is a Benelli M4 with Pistol grip model 11707. I have upgraded it with both the Collapsible stock and magazine extension to make it 7+1, This also comes with the stock parts to convert back. I also added a Front night sight ( I do have the rear night to go with this ) I just preferred having the front on only. I also upgrade to a KZ USA forearm, Holds 14 spare rounds and adds Extended Rails on TOP, Bolt Side and Bottom. I also added an oversized charging handle as seen in the Photos also made in USA. I also have the Original forearm which comes with it. I have never Fired this shotgun, also it is 922 compliant by adding the USA additions.
I will ship FedEx once payment clears and FFL to ship.
