M1014/11701: Limited edition flag model. Comes with a oem collapsible stock that doesn’t function. The receiver extension is neutered to prevent function. Barrel does not have removable chokes. The original release of 1-2500 came with aluminum trigger frames. Current production flag editions outside of this initial release have polymer frames. Original release had a different barrel design that didn’t have the seating ring that mates against the receiver face. Handguards were slightly different as to account for this seat ring. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock.
11703: When originally released, this was a 4 port barreled model made for low recoil rounds. Everyone hated it and Benelli would replace the barrel if asked. The shotgun would beat itself to death if standard rounds were used. It also came with the neutered receiver extension. It came with a pistol grip stock. Barrel assembly has removable chokes. Came with an aluminum trigger frame. For some stupid reason, Benelli released this model number again around 2014 with some changes. The barrel is the standard 2 port barrel. It has a regular 3 position receiver extension. It came with a polymer trigger frame. Came with a field stock. Why they didn’t give it its own model number, we will never know. These models are rare to see anymore. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock.
11707: This is the gold standard model. Comes with a 3 position receiver extension. Barrel is a 2 port barrel with removable chokes. The barrel have the new seat ring design and some modifications to the barrel extension inside the receiver. Early production models came with aluminum trigger frames where as current production models have the polymer ones. We’ve seen some minor changes in finishes on small parts like the Argo plugs and receiver anodizing over the years. Some Receivers almost have an OD green hue. These models come with a 5 round magazine that has a limiter in place. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock. I will note that 60 were released from Benelli with 7 round magazines and functional collapsible stocks until the ATF made them stop.
11710: This M4 essentially the same as a 11707, but it comes with a field stock.
11711: This model has all of the features of the 11707, but the shotgun was plated in Np3 by Robar. These are quite rare and not to be confused with the Cerakote model that is painted silver to copy the look. These true NP3 plated models are arguably considered the best model due to the performance of the Np3 finish. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock.
11713: This M4 is a law enforcement model that is 922(R) exempt like the 11721. This model has all of the features of the 11707. The only real difference is it comes with a steel 7 round magazine tube.
11717: This model has all of the features of the 11707, but the shotgun has a three tone desert camo pattern. 922(r) rules apply for modifying the shotgun’s capacity and collapsible stock.
11721: This is a law enforcement model that has all the features of the 11707 but doesn’t have to abide by 922(R) restrictions. It isn’t meant to be sold to civilians, but they often are. They are sold at a premium price. Given that it comes with a collapsible stock, this makes the price more appealing. The shotgun includes a 7 round steel magazine tube.
11723: This is a 14” Entry gun version of the M4 the barrel doesn’t have a removable choke. This would be a NFA firearm. It comes with the field stock. Other features are similar to the 11707/11721. 5 round capacity due to length.
11724: This is a 14” Entry gun version of the M4 the barrel doesn’t have a removable choke. This would be a NFA firearm. It comes with the oem collapsible stock other features are similar to the 11707/11721. 5 round capacity due to length.
11795: This model is similar to the 11707 in features. The only real difference is it is Cerakoted. I have seen both a H2O titanium finish and a dark earth color option. Pistol grip and field stocks can be had under this model.
11796: This is a law enforcement model like the 11713/11724. The only difference is the Cerakote paint options. The firearm is generally sold with the oem collapsible stock and a 7 round magazine tube.
There may be other options and models out there. Benelli has a European model with a slightly longer barrel. There is also a redesigned M4A1 that has been floated that uses the Supernova collapsible stock and has a railed handguard assembly from the factory. I don’t think these options have been imported to America yet.
