Only the 2-Round Magazine Extension and spring is being sold. All other parts are for reference only.

When upgrading magazine capacity from 5 to 7 rounds, it is recommended to upgrade the magazine spring as well. We offer 2 options, both nearly identical, Premium Upgraded Magazine Springs on ebay as well.

The Benelli M4 magazine extension is nearly identical to the OEM extension tube, part #81043. It replaces the OEM magazine extension limiter that comes standard on all new Benelli M4s from the factory.

This magazine extension tube increases the capacity of your Benelli M4 by 2 rounds. Increasing the total capacity to 7 shells of 2-3/4, or 6 shells of 3. Ghost loading increases each shell count by an additional 2 rounds (nine 2-3/4 or eight 3).

The Benelli M4 magazine extension is coated in a H2O cerakote to match the Benelli M4 H2O version. It will closely match the Titanium Cerakote Benelli M4's but may vary slightly.

Precision CNC Machined from high strength and low weight titanium allow

Unlike many aftermarket Benelli M4 magazine extensions, ours slides through the middle barrel ring when field stripping without having to unscrew the extension. This saves a lot of time, hassle, and bent magazine springs.

This part is machined and coated in America. This magazine extension doesn't replace the entire assembly (5-round tube and limiter) as our full-length magazine tube does, so it doesn't count as a 922(r) part.

It only weighs in at 1.8oz, even less weight than the aluminum 2-round limiter. Is 6.5 inches long, just like the limiter and the Benelli OEM 81043 magazine extension.

This magazine extension is made for the Benelli M4 specifically and is not guaranteed to fit any clones.

Installation is very quick and easy. It can be installed in less than a minute with some experience.

Installation:

1) Unload M4 and put on safety glasses.

2) Remove magazine cap, barrel, and unscrew limiter.

3) Use snap ring pliers and carefully remove the retaining ring.

4) Screw on new magazine extension firmly.

Install retaining ring into the new magazine extension.

5) Reinstall barrel and magazine cap.
