What is a Benelli M4 Magazine Extension?
A Benelli M4 magazine extension is a tube designed to be added ahead of the magazine tube to increase its capacity. It is a simple screw-on design that can be easily attached to the mag tube.
The extension comes with its own spring which is longer than the original factory spring. Some extensions even come with their own follower, although that is not necessary.

How to Pick a Great Magazine Extension
When selecting a magazine extension for your Benelli M4 shotgun, keep these aspects in mind:
Fit and Durability
Before you buy a benelli M4 magazine extension (or any shotgun mag tube extension), ensure that it is easy to install and remove. Attachments are always better than replacing the entire mag tube because you can put it on or off when you need.
Always pick extensions made from good quality materials so they do not compromise the overall integrity of your shotgun.
Capacity
Extensions for the M4 usually add one or two rounds to the mag tube capacity. However, there are a few rare ones on the market that allow the mag tube to hold as many as 10 rounds. Two extra rounds is enough in my opinion. Plus, having any bigger extensions will disturb the weight balance and ergonomics of the shotgun.
Legal Implications
Before you buy a magazine extension for your Benelli M4, make sure to check your local laws and regulations. Check out if your local state laws allow adding an extension, or the maximum capacity allowed.
For example, using a shotgun for waterfowl hunting usually requires a hunter to limit the capacity to three rounds. Similarly, be aware of the 922r compliance for shotguns like Benelli M4, especially you live in restrictive states like CA or NY.

Best Benelli M4 Magazine Extension Overall:
Carlson's M4 7-Shot Extension
Pros

What Recent Buyers Report
https://www.opticsplanet.com/carlson-s-choke-tubes-benelli-m4-7-shot-magazine-extension.html
The Carlson's Benelli M4 magazine extension has mixed reviews, but most of them are on the positive side. Almost everyone was impressed by the quality and fit of the extension. Although, a few people found it a bit too long and the color a bit greyish.
As far as the performance is concerned, the extension works really well and meets its expectations. A few buyers frowned that it added only one more shell to the tube, but they were using 3" shells.
Why it Stands Out to Us
This extension is made from high-quality steel designed to be flexible and strong enough to handle extra rounds. If you use 2-3/4" shells, this extension will add two more shells to your magazine. Adding and removing the extension is fairly easy and it stays in place with no wobble whatsoever.
Given its meager price tag where other options roll well over $150, the Carlson's Benelli M4 magazine extension is an amazing deal for sure.
Who Will Use This Most
This extension will feel perfect for home defense, tactical and range goers. The seven round capacity (plus one in the chamber) gives you extra firepower and confidence in home-defense situations.
The swivel stud attachment point ensures that you can attach a sling and carry your shotgun for long durations. So adding this extension tube does not impede with usual functionality.
Bottom Line
If you want a high-quality magazine tube extender that will last you quite a while, look no further than this Benelli M4 magazine extension. Made from high grade blued steel, this extension gives you two more rounds in your semi-auto shotgun. The extension makes your shotgun good for defense, tactical, and range use.
Runner-up:
Choate Tool Benelli M4 +2 Extension
Pros
Cons
What Recent Buyers Report
A lot of new users were looking for an extension that would at least give them two additional rounds for their shotgun. This Choate Tool Benelli M4 magazine extension solved their problem for sure.
The design is durable and doesn't feel flimsy at all. The included mag spring may feel a bit too long, so some users decided to stick with the factory spring. Installation and removal is very easy, and the extension gives you the best bang for your buck. Although, Choate should have included a follower in the package.
Why it Stands Out to Us
While itโs similar to the previous model we reviewed, it serves its purpose of doubling your shooting capacity. The solid steel construction testifies about its durability and ensures that you'll have it intact in the long term.
The sandblasted matte blued finish is good for the long term because you don't have to worry about it losing the gloss. The spring is slightly longer than the factory spring to build up that pressure to push the two extra shells.
Who Will Use This Most
This extension is probably the best for people who go rough with their shotguns. Making it suitable for rugged range use or tactical use. Frankly speaking, this is just a magazine extension that adds two more rounds to your semi-auto shotgun. So you can use it for whatever purpose you feel fit for your M4.
Bottom Line
The Choate Benelli M4 magazine extension adds to more shells to your mag tube and is fairly durable in construction and finish. The package should've included a follower as well, but at this price point, there's little to complain.
How to Install a Shotgun Magazine Extension

Conclusion
The Benelli M4 is a gas operated semi-auto shotgun. Which means that it can fire shots faster than a pump action shotgun and consume ammo quickly. That's where a Benelli M4 magazine extension can come in handy and provide you with some extra firepower.
However, mag extensions for the M4 are a bit hard to come by, and you must also make sure that it complies with your local laws and regulations.
