7 Best AR-15 Handguards (MLOK, Keymod, & Picatinny)
Looking to upgrade your AR and want the best AR-15 handguard? If so, we got you covered.
There are an endless amount of rifle parts to buy, and some of them are better than others.
All the handguards recommended in this post will work great and give you better mounting capabilities.
This post will review the best AR-15 handguards.
Why Upgrade Your AR-15 Handguard?
The main reason to upgrade your handguard is to gain more usable rail space for attaching accessories such as lights, lasers, foregrips, and bipods.
A streamlined mounting surface will give you more flexibility in an accessory placement, making your AR platform more customizable to your shooting style and setup.
Depending on what handguard is currently installed on your AR, a new one may lighten the weapon and reduce weight.
Also, going with quad rails will most likely add weight to your current setup so keep that in mind.
If you go with a free float handguard, this will improve the accuracy of the AR.
Best AR-15 Handguard Criteria
Many options and factors exist when looking for the best handguard for your AR-15.
It can be overwhelming to navigate all the different types and brands available on the market. However, by considering your specific needs and preferences, you will be able to find the perfect handguard for your rifle.
Factors to consider include the material of the handguard, the length, the attachment system, and the accessories you will be mounting.
By evaluating these factors and researching, you can determine which handguard best fits your rifle and shooting needs.
Below are the variables I think about when choosing the best AR-15 handguard that you should also consider.
Keymod
A Keymod-style handguard is a good choice but becoming less popular than an MLOK style. Right now, there are still plenty of accessories made for keymod, but it seems the trend is going toward MLOK.
Keymod is lighter and more comfortable than the 1913-style Picatinny quad rails.
Another benefit of the keymod handguard is its enhanced ergonomics. The keymod system allows for a comfortable and secure grip, which can improve accuracy and control.
Additionally, keymod handguards often feature a sleek and minimalist design, which can give the rifle a more modern and tactical look. The keymod system also offers a more efficient cooling method by allowing air to circulate the barrel. This can be especially beneficial when using the rifle for extended periods.
MLOK
An MLOK handguard is now the most popular choice for AR-15 users due to its versatility and ease of use.
One of the main benefits of using an MLOK handguard is the ability to attach accessories to the handguard easily. The MLOK system uses a series of slots along the handguard, which allows attaching accessories without additional hardware.
You can easily customize your rifle to suit your needs and preferences. MLOK handguards are often lightweight and ergonomically designed, making them comfortable and easy to hold.
They also typically feature a solid construction, which provides added durability and protection for your barrel.
Picatinny
The good old cheese grater handguard has the most combat use and is known for being the most solid style handguard.
A 1913 Picatinny quad rail is the heaviest and the least comfortable style. But it is the strongest.
Like everything with firearms, there is always a trade-off.
These may seem a little dated to some people, but they are proven and reliable.
Free Float
Free float handguards are handguards that are not attached to the rifle’s barrel and instead are mounted to the receiver at the front of the rifle.
This design allows the barrel to float freely within the handguard and eliminates any pressure points that could affect the barrel’s accuracy.
The free-floating design also makes the rifle more stable when shooting, making it easier to control the recoil and improve accuracy.
Drop-In
On the other hand, drop-in handguards are designed to be installed directly into the rifle’s receiver.
They are typically more affordable than free-float handguards and are easier to install as they do not require gunsmithing or special tools.
However, drop-in handguards can affect the rifle’s accuracy as the barrel is not free-floating, and pressure points can cause the barrel to move slightly.
Durability
The modern handguards I list below are durable and would be a good choice for anyone.
It comes down to personal preference and how you plan to set up your rifle.
Do you want a lightweight home defense gun, a good all-around general-purpose rifle, or a specialized marksman rifle?
Quad rails will always be the strongest and most reliable.
Comfort & Weight
Keymod and MLOK will be the most comfortable to grip and hold while shooting or even just carrying the rifle for extended periods.
They have less raised surfaces and are smoother.
You can get rail covers for any style of handguards, which will help while carrying, but the lighter the rifle overall will make it more comfortable.
Length
Deciding on which length of handguard you want will depend on your gas tube. Also, how much rail space do you want or prefer?
For example, if you are running a weapon light or a bipod, you generally want both accessories as far forward on the rifle as possible. So a handguard that extends the entire length of the barrel might be better.
If you want the lightest setup possible, then a short MLOK handguard might be the best.
Price
The final and most significant deciding factor for most people is the cost of a new handguard. They will typically run from $100 to $400, depending on which style and length of handguard you choose.
Again all of the ones I recommend below are good quality and will work great.

Final Considerations
A lightweight handguard that is also a free float handguard is what I recommend. When you mount accessories to a quad rail, it will always be the strongest method.
A free floating handguard is a rail system that is usually a high quality handguard.
Carbon fiber handguards are not as common or durable as aluminum handguards and ones that I normally do not suggest.
Any rail system that are free float handguards seems to be the trend lately.
Best AR-15 Handguard FAQ
What is the best material for an AR-15 handguard?
The best material for an AR-15 handguard is typically a lightweight and durable polymer or aluminum alloy. These materials offer a balance of strength and weight, making them ideal for use on a rifle.
What is the difference between a free-float and a drop-in handguard?
A free-float handguard attaches to the rifle at the receiver end only, allowing the barrel to float freely inside the handguard. A drop-in handguard, on the other hand, attaches to the barrel and the receiver, which can affect the rifle’s accuracy.
How do I install a new handguard on my AR-15?
Installing a new handguard on your AR-15 typically involves removing the old handguard and attaching the new one to the receiver and barrel. This process can vary depending on the specific handguard and rifle, so it is important to consult the manufacturer’s instructions for proper installation.
Are there any specific handguards that work well with suppressors?
Yes, there are handguards specifically designed to work well with suppressors. They are known as suppressor height handguards. They are taller than standard handguards to accommodate the added length of a suppressor and protect the shooter’s hand from the heat generated by the suppressor.
Are there any handguards that offer a rail system for accessories?
Most handguards offer a rail system for accessories such as lights, lasers, and bipods. These handguards typically feature a Picatinny or M-Lok rail system that allows for easy attachment and detachment of accessories.
