Benelli 81043 M4 LE 2-Shot  Mag-Extension Kit

Benelli M4 LE 2-Shot Magazine Extension Tube | 81043

The Benelli 81043 is a factory 2-shot magazine extension tube designed for the Benelli M4 12-gauge shotgun. For M4 owners looking to add magazine capacity while keeping the shotgun equipped with genuine Benelli components, this is the OEM extension tube rather than an aftermarket alternative.

This part is the extension tube only. It is not a complete magazine-extension kit, so the remaining magazine components required for installation and operation must already be present or sourced separately.

Factory Benelli M4 Magazine Extension

The 81043 is designed specifically for the Benelli M4 platform and adds two rounds of magazine capacity when installed as part of the proper magazine assembly.

For owners who prefer factory Benelli components, the 81043 provides an OEM solution that maintains the original appearance and fit of the M4 platform.

Steel Construction

The extension tube is manufactured from steel and finished in matte blued black to match the functional, duty-oriented finish of the Benelli M4.

Its straightforward design extends the existing magazine system without changing the basic layout of the shotgun.

Extension Tube Only

IMPORTANT: The Benelli 81043 includes the magazine extension tube only. A magazine spring retainer, magazine follower, magazine spring, and magazine cap are required for a complete functional assembly and are not included.

Before ordering, confirm which magazine components are already installed on your M4 and which additional parts will be required to complete the conversion.

Designed for the Benelli M4

This extension is intended for Benelli M4 12-gauge shotguns. Using the correct manufacturer part number is especially important with M4 magazine components, since full-length tubes, extensions, springs, retainers, and caps are separate parts and are not always interchangeable between configurations.
