Now that we've compared the best M4s, let's get down to the features that make these airsoft guns standout options and why you should check them out.
The Best Airsoft M4s for Beginners for 2022
The G&G Combat Machine 16 Raider Airsoft AEG Rifle is a modernized and updated version of an airsoft classic that's an excellent choice for entry-level players who want the perfect combination of value and performance.
This M4-style copy is jam-packed with features like the M16 triangle sight mounted on the front of the cannon, which may be adjusted for elevation.
Externally, the outer barrel is 14.5 inches long and composed of aluminum. This barrel fashions a 7" quad rail system, providing plenty of rail space for accessories. And the rail system is built of a lightweight polymer that's both sturdy and lightweight.
Also, the rail system and the body are composed of the same polymer material. You may adjust the rear sight for windage and elevation, and you can also remove it if you prefer a different sighting system, such as a red dot sight or scope.
Internally, the CM16 raider gearbox has a full metal V2 upgradeable gearbox powered by a 9.6v NiMH or a 7.4v Lipo battery.
Another point worth noticing is that the 11.1v Lipo batteries are more powerful and can be utilized to power the airsoft rifle for a faster rate of fire and crisper trigger response but at the expense of increased rifle wear and tear. So, snatch up the gun because it's often sold out!
The G&G Combat Machine 16 Raider Airsoft AEG Rifle is arguably the best M4 out there for first-time players. It's incredibly sturdy, can withstand a thrashing, and is still lightweight.
Most Reliable M4
The KWA Full Metal KM4A1 Airsoft AEG Rifle is one of the most popular M4 carbine-style AEGs available. At under $200, this airsoft rifle is a bargain, as it's upgradeable and reliable. That's because the KM4A1 is made of a high-quality, rock-solid aluminum alloy for durability.
Moreover, its M4A1-style handguard provides you with a very comfortable grip when shouldering the airsoft gun and gives it a more "old-school" appearance. It also includes an ambidextrous rear sling mount, ideal for single-point slings and a front and rear sling loop mount for two-point slings.
Internally, the KM4 A1 is built to last and is an outstanding performer. With its new 2GX gearbox and 2G high-performance hop-up bucking, this rifle is marked by its quick rate of fire and highly responsive trigger, putting extra pressure on the enemy right out of the box.
Here's something to remember as well: you may update the airsoft gun with any V2 compatible internals, which are even more robust than typical V2 gearboxes, thanks to the reinforced 2GX gearbox.
Nonetheless, we have to say that the rifle's orange paint comes off a little too easily. Also, it has un-adjustable hop-up.
The KWA Full Metal KM4A1 Airsoft AEG Rifle is one of the few airsoft guns that appeal to a wide range of people, regardless of their interests. The KM4 always delivers and accommodates everyone, from newbie players who have managed to save up to experienced vets searching for a solid platform for their next build.
Best Scout Rifle
The Krytac Full Metal Trident MKII SPR Airsoft AEG Rifle is the modern rifleman's first choice. It's essentially a scout rifle that thrives at medium and longer ranges in a large open field setting.
Externally, the SPR has a somewhat longer outer barrel than others and a mandatory blaze-orange pronged flash hider. It also uses a Keymod handguard rather than the more common M-LOK configuration.
The Keymod system is essentially a scaled-down airsoft version of the industrial shelving slot configurations you've undoubtedly seen in hardware stores.
On semi-auto, the Trident SPR has a rapid trigger, and on full auto mode, it can swiftly put a substantial quantity of BBs in the air!
If you put the Krytac SPR through its paces on a chronograph with 20g BBs, you'll get an FPS of roughly 390. This is the best area for a field-type AEG.
In addition, the Trident MK2 SPR has an 8mm gearbox with integrated MOSFET to manage electrical signals and protect the trigger contacts on the inside. A small aperture on the left side of the gearbox shell allows lubrication to be delivered directly to the gears or piston. But if we were nitpicking, we'd say that the gears are slightly off-spec.
Overall, the Krytac Full Metal Trident MKII SPR Airsoft AEG Rifle is ideal for those who have some experience and are willing to upgrade to an AEG that'll complement their scout and fieldcraft skills. Additionally, it's a no-brainer for outperforming your competitors, thanks to its infinite Keymod customizability, high stock FPS, and great mid to long-range accuracy.
Best Looking Rifle
The EMG / SAI GRY AR-15 AEG Training Rifle is a unique rifle developed to produce outstanding performance in any environment. It's geared squarely at experienced players. And given its lack of semblance to anything used by various militaries throughout the world, MilSim-oriented players are likely to stay away.
The GRY AR-15's most distinctive feature is its Jailbreak muzzle. You can add or remove the Jailbreak at any time, letting you mount your accessories easily without having to worry about your barrel getting in the way.
Moreover, the GRY is very lightweight, thin, and durable. Not to mention, it comes with a standard orange birdcage flash hider pre-installed. It has an M-Lok design with Picatinny rails upfront for attaching the Jailbreak device and flip-up sights!
Additionally, the gun's MOSFET works overtime to produce a super sensitive trigger that only requires a small amount of motion to turn the gearbox over and fire. This way, you'll be able to snap swift semi-automatic shots with near-instant follow-ups!
Also, a five-shot chronograph test reveals a +10 FPS difference between 365 and 375 FPS. But the good news is that most field chronograph limitations in that FPS range are likely to be unaffected, as most fields are around 400 FPS for open, woodland-type conditions. But if you never want to worry about chronoing hot, the 370s are pretty much the sweet spot!
Also, note that each of the lateral Picatinny rails has a QD sling mounting point, with two more points further back where the rail joins the receiver. We wish the gun had an electronic figure micro switch and a less tight dean connector.
If you're searching for a high-end AEG that doesn't sacrifice aesthetics to provide you with a high-performing airsoft rifle, you need the EMG / SAI GRY AR-15 AEG Training Rifle on your list.
Most Versatile M4
The Krytac War Sport Licensed LVOA-C M4 Carbine Airsoft AEG Rifle is among the most durable and versatile rifles you'll come across today. The Watersport LVOA-C fashions a top-notch exterior made of solid steel and a rugged, high-performing interior that gives you the feel of a real pistol.
This neat airsoft gun carries a strengthened 8mm gearbox with a MOSFET system. This is essential because the gearbox regulates electronic signatures and protects the trigger contacts.
In addition, the gearbox shell has a small window on the left side through which you can apply lubricant directly to the gears or piston. This window is also useful for checking engagement when the gearbox is assembled.
Looking at the build now, this airsoft gun comes with the WARSPORT LVOA-C Rail System and a full-length top RIS rail, allowing you to mount your choice optics and accessories with ease.
With its new unique stock design that adjusts to six positions and comes with a Triple Battery Configuration set-up, this new model will let you shoot with more range while reducing downtime on the field. We don't love how the rail system covers flash fider, though.
With 380 FPS potential and a great manufacturer's guarantee, the Krytac War Sport Licensed LVOA-C M4 Carbine Airsoft AEG Rifle is an outstanding and incredible weapon. It's a highly adaptable and versatile platform that performs well in close quarters and mid-to-long-range engagements. And it’s excellent if you want the ultimate field rifle.
Best for Improved Performances
The KWA Full Metal KM4 SR7 CQB Airsoft AEG Rifle is an M4 variant produced by the US Naval Special Warfare Development Group. It's what you'd call the ideal CQB rifle.
On the inside, the SR7 is a super-efficient machine. It's designed for high-speed firing over 20 rounds per second while maintaining a velocity of over 350 feet per second, which is within the limits of most enclosed arenas.
On the outside, this rifle is composed of a full alloy construction, a MIL-SPEC-1913 Picatinny free-floating rail adapter system, 2GX gearbox, 2G High-Efficiency Bucking, extendable flip-up front and rear sights, flat top receiver, matte finish with personalized identification numbers, and more exciting features.
The installation of the 2G High-Performance Bucking has substantially improved the accuracy of this rifle. In addition, its bucking is equipped with a set of specially developed "Fins" that deliver incredible consistency shot after shot.
All KWA inner barrels are now made in Japan using the most advanced machining technology, resulting in superior quality and performance. This rifle's barrel isn't any different. Additionally, the 7-inch free-float rail system makes it simple to add tactical accessories like foregrips and weapon lights.
Moreover, the SR7 is based on the KM4A1 chassis and has a complete metal alloy build with the 2GX gearbox for long-term durability and strength. It also provides operators with a versatile weapon system that's quick and maneuverable. However, the front sling mount is somewhat noisy.
With a hard-to-beat price and an ever-improving performance, the KWA Full Metal KM4 SR7 CQB Airsoft AEG Rifle is easily the go-to gun for M4 enthusiasts. Also, the SR7 is the ideal gun for close quarter battles.
KWA was one of the first AEG manufacturers to offer a pistol that required minimal internal changes to perform well right out of the box, hence the Evike Custom KWA VM4-A1 V2.5 / M4 RIS Carbine Airsoft AEG Rifle.
Furthermore, the KWA VM4A1 Version 2.5 Airsoft AEG is one of the best-engineered airsoft weapons available at a reasonable price for more casual gamers.
The KWA VM4-A1 RIS's most outstanding feature is the Variable Performance System (VPS). It allows you to customize the AEG's FPS through the stock tube with a provided tool and tune the rifle between 390 and 440 FPS. This way, you can have the exact performance you need in any given situation.
This variant of VM4 comes with its perks as well. It has a 2.5 gearbox that provides new high-speed gears, 9mm bearings, an upgraded high torque motor, and KWA's switch life extender for long life when utilizing high-powered batteries.
Not to mention, the VM4A1 has a full metal receiver set and a PTS pistol grip on the outside. In addition, it's rear wired into a 6-position stock that can use most nunchuck-style batteries. All of these features work together to make the classic rifle even better, providing any player with a solid and consistent performance on the field. We have to say that it's a fairly heavy one, though.
The Evike Custom KWA VM4-A1 V2.5 / M4 RIS Carbine Airsoft AEG Rifle is the perfect AEG rifle for MilSim and field gamers that want to outwear their opponent. With 1-piece solid metal alloy upper and lower receivers that minimize weak areas, this modernized classic elevates the M4A1 model to a new level of performance and packs so much value.
Best for Long and Medium Range Operations
The EMG Colt Licensed M4 SOPMOD Block 2 Airsoft AEG Rifle has been crafted after the original ArmaLite AR-15. This AEG rifle has been particularly popular in the United States military and among numerous civilians since the emergence of the M16 combat rifle. Its muzzle velocity of 400 FPS renders it suitable for long and medium operations.
Today, the EMG Colt has become a go-to option for many rifle enthusiasts. This is mainly owing to the rigorous use and first-hand feedback to develop the AEG industry.
You can admire the authentic designation and COLT marks on the receiver and the Daniel Defense MK18 RIS handguard, thanks to a license from American Daniel Defense, a maker of parts for the live rifle original.
And its appearance was meticulously recreated using licensed pieces from the original live pistol. To illustrate, the body build is made of a floating, two-piece front rail system. Even with this rail system, the Colt remains lightweight. In addition, it has an extensive mounting surface for all 20mm Picatinny supplements.
Additionally, the Colt was created to fit an M203 grenade launcher without any extra tools. Moreover, the rifle was primarily built of high-grade aluminum. If we take a look inside, it has a well-fitting, tight system based on a reinforced gearbox V2 with 8 mm bearings on the inside.
The connector is a low-resistance micro DEANS (T-connect). In the stock pipe, the battery is kept. The use of a high-speed motor and a MOSFET improves the replica's quality and reliability.
This rifle has a modular, restricted rotation, which is provided by QD swivel mounts to fit your likes. Its free-floating, ultra-lightweight design also makes for faster target acquisition. But the pistol grip could've been improved.
The EMG Colt Licensed M4 SOPMOD Block 2 Airsoft AEG is known for its high consistency in functioning and successive shot repeatability. This rifle's internal parts are of exceptional quality, allowing it to reach a muzzle velocity of 400 FPS. It's arguably perfect for medium and long-range operations while also providing a good foundation for further tuning.
For Pistol Enthusiasts
KWA QRF Pistol Caliber AR is the airsoft rifle most pistol enthusiasts have been waiting for. The Mod. 1 was inspired by a cross between an SMG and a Pistol Caliber Carbine. It was developed by some of the world's top airsoft designers and engineers.
The receiver is designed to look like a PDW rifle but with a pistol caliber magwell. KWA's new M-LOK handguard is included on the front, along with a newly created anodized flash hider. Also, left and right-hand users will like the ambidextrous fire selector, mag release, and sling adaptor.
The innovative lever-style magazine release on the QRF MOD1 is legendary. The PDW butt stock's cheek weld has been removed, and it now has a MOD1-style structure.
There's also a quick-change spring system for changing the FPS range to meet your mission. Still, the FPS is a little too high for CQB. And a new high-torque motor and high-speed gear set are included in the gearbox for dependable performance.
There's also a switch life extender and room for drop-in ready MOSFETs like the GATE Titan in the gearbox. Overall, it's no surprise that KWA has introduced these breakthrough models to help the airsoft business and community thrive.
If you've been seeking a pistol caliber carbine, the KWA QRF Pistol Caliber AR is an ideal option for enthusiasts looking for a hybrid airsoft gun. It's equipped with KWA's unique AEG 2.5 gearbox, which employs the company's Variable Performance System.
Best for Realism
The KWA 3.0 Ronin Tactical T10-SBR is incredibly well-built on the outside with high-quality materials chosen for the externals. It has a rail system that accepts 20mm RIS/RAS and M-LOK accessories. And it makes for such an immersive experience!
Internally, the KWA 3.0 Ronin Tactical T10-SBR has a fully upgraded and reinforced full metal gearbox. It features 9mm Steel Bearings, a high torque motor that produces 20% faster speeds than standard, and cutouts ready to accept drop-in Electronic Trigger Units.
The 'KWA Kinetic Feedback Mechanism' is, to those of us who can look past marketing hyperbole, a hard-kicking mechanical recoil system that'll shake your body. It's this robust workhorse's big party trick.
Instead of a poxy dust cover rattling about, this system simulates recoil by moving a considerable weight in the Buffer Tube, resulting in a considerably louder 'oomf' each time you squeeze the trigger.
What's more is that this gun comes with a Quick Change Spring System, which allows you to change the mainspring in your pistol without disassembling it. You can access the system at the back of the Buffer Tube, and it's highly recommended that you wear eye protection throughout this process because the recoil system adds extra tension. The only drawback is that getting the faux bolt to lock back for Hop-Up adjustment is a pain, but this is a slight annoyance.
If you're interested in raining BBs on your opponents and feeling every shot taken alongside, The KWA 3.0 Ronin Tactical T10-SBR is your best bet. It gives you an immersive experience and offers excellent value for money.
Should You Get an Airsoft M4?
Yes, it's a good idea to get an M4 when beginning your Airsoft journey. The M4s are a budget-friendly way to get a fully customizable and high-quality weapon.
Not only is it efficient, but the M4 is generally the most versatile weapon platform available. Plus, the weapons are loaded with new technology at the same price or even lower than platforms like the Tokyo Marui. (1)
How to Choose the Right Airsoft M4 for You
Here's how to pick your ultimate M4 like a professional:
Many people prefer an M4 weapon that's nearly identical to the actual thing. This encompasses not only the rifle's appearance but also how it feels when you fire it. For instance, C02-powered weapons usually produce the most realistic kick. (2)
The muzzle velocity of the best M4 airsoft rifles is crucial because they get the majority of the CQB action. However, high muzzle velocity can be a disadvantage in an airsoft game with multiple players.
Strong firearms might cause injury to other players and get you kicked out of the game. However, most M4 and Ar-15 rifles have 350 FPS, which is sufficient for CQB circumstances.
Ease of Use
You should always consider the size, weight, and existence of ambidextrous controls of your preferred M4s. It also helps if the rifle has or can be fitted with a fore-grip. In general, choose a rifle with a collapsible stock, a metallic or ABS body, and maybe sling mounts to make it easier to carry in a field.
Frequently Asked Questions:
What Is the Difference Between an AR15 and an M4?
The M4 is frequently referred to as the military's counterpart of the AR-15 and vice versa. However, this isn't entirely accurate. The M4 is a carbine version of the M16, which is the real military version of the AR-15.
In addition, the M4 is a rifle with a carbine-length barrel. This means it comes with a 14.5-inch barrel. The standard AR-15 barrel is 16 inches in length. Thanks to a cutout in the barrel, the M4's barrel can be fitted with a grenade launcher as a military weapon.
What Does Front Wired or Rear Wired Mean?
Typically, the M4 family of firearms are wired from the front or rear. This implies that the wires from the gearbox will terminate at either the front or rear of the gun's battery connector. This will influence the size and shape of the battery you select.
Ultimately, whether you're a novice, trying to upgrade from your first gun, or searching for something to take you to the next level, any of the guns on this list will serve you well. Still, the G&G Combat Machine 16 Raider Airsoft AEG Rifle is probably our favorite, thanks to its lightweight, sturdiness, ambidextrous handling, and more.
We also like the famous KWA Full Metal KM4A1 Airsoft AEG Rifle. With its reliability and upgradability, who wouldn't? And we can't forget the Krytac Full Metal Trident MKII SPR Airsoft AEG Rifle, enabling shooting from medium and long ranges.
