UPDATE From Benelli:
"Due to the prolonged delay we were experiencing with the ATF approving final paperwork, we had to discontinue this item and all backorders are cancelled. We will be coming out with similar models in the first quarter of next year (2014). The only difference is that they will not have the extended magazine capacity or any type of collapsible stock…..just standard tactical or pistol grip stocks." Dated October 2013
Now the same Benelli M4 used by the U.S. Marine Corps can be your home defense shotgun of choice. When the U.S. Marine Corps went shopping for a shotgun, they bought the M4 — the 12-gauge shotgun that functions the first time, every time. Its unique Auto Regulating Gas Operated (A.R.G.O.) system developed by Benelli engineers has dual stainless steel, self-cleaning pistons located just ahead of the chamber that operate directly against the bolt assembly.
