Best Benelli M4 Upgrades: Which Part Should You Upgrade First?

Created by the famous Italian firearms manufacturer, the M4 is a tactical shotgun. The gun can use lots of accessories and you can upgrade quite a bit on the gun. Starting from the muzzle to the stock, you can modify the gun a lot.

Just like upgrading any other gun, you may find yourself in a pickle choosing the right parts for the M4. Don’t worry, you are here to help and I’m more than willing to help. Without further ado, let’s find out the best Benelli M4 upgrades.

Benelli M4 Stock Upgrades

The first thing that you may want to upgrade on your gun is the butt stock. The synthetic factory stock might not be the best thing for you. Let’s find out some of the best stocks for Benelli M4.

1. Benelli M4 Collapsible Stock

The first stock I want to recommend to you is from Benelli themselves. This collapsible stock is made out of synthetic material. While the stock might feel similar to the factory default stock you have in your hand right now, this one is a bit more durable and as the name stated, collapsible.

Collapsible stocks are good for storing the gun in a compact bag and carrying it far away from your usual routes. The stock is not a cheap part by any means. In fact, it’s one of the most expensive upgrades you can do to the gun. But it’s one of those upgrades that will leave a satisfactory smile on your face.

Benelli M4 Magazine Upgrade

Upgrading the magazine is often overlooked because of legal issues. If your state allows you to use extended magazines and won’t put you behind the bars for upgrading your magazine, then you absolutely should upgrade your magazine right this instant.

1. Freedom Fighter Tactical Magazine Tube

If you are planning to upgrade your round limit, then you will need to upgrade the magazine tube. Depending on the magazine tube, your total upgrade limit will be different.

The Freedom Fighter Tactical Magazine tube is available in stainless steel, and a Titanium Variant. Both of the materials are rust-free. The durability of their magazine tube is excellent. Much better than the stock one.

If you are using 922(r) and concerned about the stability issue after adding a magazine tube, then you might want to add an M4 FFT follower. This follower will remove all the stability-related issues from your gun after adding a magazine tube.

Benelli M4 Handguard Upgrade

The next obvious upgrade is the handguard of your M4. The stock handguard of the M4 is quite good and you can live without changing it. But by adding a different handguard, you can improve the stability, and the ability to grip better and some of them come with the option to add more accessories.

1. Benelli M4 Truckee Handguard

Mesa Tactical is a great brand for different gun accessories. This accessory for M4 is also made by them. Mesa Tactical took a different approach when it came to this handguard.

Instead of going with the traditional stainless steel or polymer for the handguard, Mesa Tactical used aluminum as the material. The CNC machining on the handguard is flawless and the matte black finish on this looks absolutely gorgeous.

Choosing aluminum has two benefits, it’s lightweight and it will never catch corrosion. And in terms of heat dispersion, this one is quite good as well. Another benefit of this handguard is, that you can easily add Blue Force Gear Padded Vickers Sling on the gun. It’s easily one of the best slings for Benelli M4.

2. Agency Arms Benelli M4 Handguard

If you want a handguard with MLOK rail compatible for adding more accessories down the line, then this handguard is the perfect choice for you. The material for this handguard is 6063 machined aluminum.

It’s light and extremely durable. The longevity is remarkable. The mil-spec hard anodized coating on it looks really nice. The finish also feels premium to the touch.

Benelli M4 Muzzle Upgrade

Often you will see shotgun users upgrading their stock muzzle with a choke or different types of brakes. Muzzle brakes are essential for reducing recoil. That’s why upgrading the Benelli M4 muzzle brake should be a top priority in your list.

1. Carlson’s Beretta Benelli Mobil 12GA Tactical Muzzle Brake

If you are looking for an all-rounder choke device that will let you shoot all sorts of shotgun shells through it, then this tactical muzzle brake is unbeatable value. The brake is made out of 17-4 heat-treated steel.

The heat dispersion of this muzzle brake is quite good. The brake is available in two designs. Extra full and cylinder. If you are a hunter and want to shoot larger shots for coyotes, then go for the extra full variant. For everything else, the full choke is a good option.

2. Carlsons Choke Tube Beretta Benelli Mobil 12 Gauge Flush Mount

If you just want to shoot slugs and chokes and don’t really care about anything else, then this choke tube from Carlsons is the perfect choice for you. It’s minimalist when it comes to looks and doesn’t fall off in terms of performance either.

The choke is made out of stainless steel. Yes, the same 17-4 heat-treated steel. The same type of steel much more expensive muzzle brake uses. So, in terms of durability, you are not missing out on anything. As it can shoot slugs, it’s a hit product among the shotgun community.

Benelli M4 Optic Upgrade

The next obvious upgrade is the optic. While you can use a riflescope on this gun, it’s not a practical choice. The practical choices are obviously holographic or red dot sights for CQB. Whether it’s hunting or tactical swat, you will never find yourself in situations where you would want an 8x riflescope on it.

1. Aimpoint Micro T-2 Red Dot Reflex Sight

Aimpoint Micro T-2 Red Dot Reflex Sight

When it comes to making quality red dot optics, Aimpoint is one of the top brands in the world. Their compact and lightweight red dot sights are used by military enforcement even.

The Micro T-2 is made out of high-quality aluminum and it features a fully multi-coated bright lens. The reticle is a 2 MOA red dot and it glows. The brightness of the red dot can be adjusted through the side buttons. It’s durable enough to be used with a shotgun and the zero won’t move just because you are using a shotgun.

2. HOLOSUN HS507C X2 Red Dot Sight

HOLOSUN HS507C X2 Red Dot Sight

Holosun is not an American brand. Yet you will see them used by Americans the most. Why is that? Well, they are affordable, they have good after-sales service, and their performance is impeccable within the price range. The 507C from Holosun is made out of durable and lightweight aluminum.

This tiny little thing is capable of taming the beast like M4 with ease. It will not need any special care while you are using it with a shotgun. Whether you are hunting with it or using it for tactical purposes, the sight will hold on its own really well. As it comes with a built-in mounting system, you will not need to pay extra for a mounting pad.

The lens of the sight is fully multi-coated and extremely bright. Thanks to the adjustable illuminated reticle that comes with night vision capability, shooting doesn’t end at dusk.

Other Benelli M4 Accessories That You Might Want to Consider

Here are some other upgrades that can be considered “minor” but are valuable nonetheless.

1. Benelli M4 Light

The first small upgrade that comes to mind is a light. If you are a nightcrawler, then you know the importance of properly equipped gears. Whether you use your M4 for tactical purposes or hunting, a light is kind of a must if you use your gun during the night. In fact, it will come in handy against burglars as well.

Something like the Streamlight TLR RM2 or SUREFIRE M600 is a good option for the barrel shotgun light for the Benelli M4.

2. Benelli M4 Side Saddle

Side saddles are there to decrease the reload time of your gun. It’s more of a luxury upgrade than a mandatory one. But it is an upgrade that will make your life easier. If you are tired of looking for bullets in your bag every time or hate wearing shotgun belts, then this is a good upgrade for you.

You can opt for the GG&G Side Saddle or the Esstac shotgun card. Both of them are compatible with the M4 and they are good options for hunters as well.

How To Choose The Best Upgrades For Benelli M4?

After seeing so many upgrade options and accessories, it’s easy to get lost among them. How do you choose the upgrades that cater to you and must for you? You can address this issue by finding out what you want. Here are a couple of pointers that might help you out.

Shooting style

Find out the purpose of your gun and the need to upgrade first. Are you a tactical shooter or a hunter? Do you need extra shots or are you fine with the stock amount? If you know these answers, then you can easily find out whether you would need an optic, a muzzle upgrade, or nah.


Most of our purchase decisions are dictated by our wallets. Chances are you are not keen on spending your life savings on upgrades for your M4. Depending on perspective, it’s a good thing. If you know how much you are willing to spend in one go, you can narrow down your upgrade choices. Later, you can upgrade things that cost more and are not an emergency need for you.

Nightcrawler or Nah

Are you a nightcrawler? If the answer is yes, you will need to buy all the accessories that allow you to shoot at night. Including a light for M4 and a properly illuminated sight like the ones I mentioned above.


That took a bit longer than I anticipated. But I hope you now know what kind of upgrades you might want to do to your M4. While there are other minor upgrades that you can do to the gun that I skimped past, these are the key ones.

And that’s all for now. Thanks for reading as always. Hope you found the best Benelli M4 upgrades and how to choose the right one for you. See you on the next one.
