One of the most important parts of your AR-15 is the handguard. It’s where you mount most of your accessories, and it’s where you hold your gun.
When we set out to find the best AR-15 handguard, we knew we were getting into some controversial territory. The reason for this is that the AR-15 is such a versatile platform.
For example, if you’re looking for a tactical rig, you’ll probably want a free float quad rail for accessories. On the other hand, if you’re building a small home-defense gun, you might prefer the best drop-in carbine handguard for an easier build. Or maybe this is your first rifle, and you’re just trying to find some cheap AR-15 handguards.
Regardless of what you’re using your AR for, we’ll cover a wide variety of styles, and cover a broad enough price range to get you into the best AR-15 forend for your needs and budget.

The Aero Precision Enhanced Handguard sports a full-length Picatinny top rail.
Key features:
- Free floating design
- 1.72-inch inside diameter
- Picatinny top rail
- Available in 12 and 15-inch lengths
- Available with Keymod or M-LOK mounting points
- 3 quick disconnect sling slots
The Aero Precision Enhanced Handguard provides generous clearance for a low-profile gas block, with a wide, 1.72-inch inside diameter. It’s forged from anodized aluminum, and has a free floating design.
The bad news is that it’s made for the proprietary mounting surface on Aero Precision’s M4E1 upper receiver. This makes it more or less useless if you’re using a different upper. However, when affixed to the M4E1, the Precision Enhanced’s Picatinny top rail lines up perfectly with the one on your receiver, creating a continuous rail that runs the length of your rifle.
This handguard is available in two lengths: 12 and 15 inches. You also get your choice of mounting points; it’s available with Keymod or M-LOK.
Pros:
- Durable aluminum construction
- Provides a continuous top rail
- Plenty of room for accessories
- Compatible with low-profile gas blocks
- Lifetime Brownells satisfaction guarantee
Cons:
- Only fits Aero Precision’s proprietary M4E1 upper receiver
This AR-15 mid length handguard is ideal for rifles with a low-profile gas block.

- Keymod mounting points
- Includes proprietary barrel nut
The Bravo Company BCMGunfighter KMR is forged from durable anodized aluminum, with an inside diameter of 1.3 inches. This is large enough to accommodate almost any muzzle attachment, but it’s still fairly small. It won’t fit with a whole lot of gas block setups, so make sure you’re using one with
The KMR is available in seven different sizes, from 7 to 17 inches. It features a full-length Picatinny top rail, and an impressive array of Keymod mounting points. Not only are they located at the three, six, and nine o’clock positions, they’re located between those positions as well, letting you mount your accessories exactly where you like them.

- 1.3-inch inside diameter
- Four Picatinny rails

- Two-piece design
The Midwest Industries Two-Piece Free-Float Forend has a split design that makes installation easy. Just cut out the factory delta ring, and clamp it over your barrel nut. No need to remove your barrel and accessories. On the other hand, this isn’t as secure as a traditional installation, so pick your poison.
This forend is designed for carbine length barrels with extended gas systems. If you have a shorter system, you’re out of luck, because the Two-Piece Free-Float Forend isn’t going to accommodate it.
The anodized aluminum construction is high quality, with four Picatinny rails at the 12, 3, 6 and 9 o’clock positions. The rail slots have laser etched numbers, which makes it easy to keep track of where you keep your accessories mounted.

The Magpul MOE M-LOK Rifle Handguard is a solid budget choice.
Key features:
- Drop-in design
- Barrel-width inside diameter
- Four rows of M-LOK slots
- 12.5 inches long
The Magpul MOE M-LOK Rifle Handguard is one of the most popular handguards for people who are building their first AR. It’s affordable, it’s lightweight, and it’s easy to install. Simply remove your front sight, slide it over your barrel, and secure it with a delta ring.
Because it’s a drop-in style, this handguard won’t accommodate a gas block. You’ll need to use it on a rifle-length AR, or on a carbine-length AR with a rifle-length gas system.
The MOE is molded from lightweight polymer, which provides a secure, comfortable grip. It has four rows of M-LOK slots, at the 12, 2, 6 and 10 o’clock positions.

Cons:
- Requires a rifle-length gas system

Key features:
- Drop-in design
- Barrel-width inside diameter
- 12 inches long
- Factory Colt replacement
The Colt AR-15 A4 Handguard Assembly is designed to fit ARs with an A1/A2/A4-style frame. It’s an original factory placement, and features the same tapered design and ridged polymer construction that made it so iconic. It does not fit on a newer M4 frame, so this is for older guns only.
Installation is easy. Remove your front sight, slide it over your barrel, set the delta ring, and you’re ready to go. As with any drop-in assembly, it doesn’t have any room to accommodate a gas block. You’ll need to have a rifle-length gas system if you want to use this handguard.
This handguard is not made for accessories. It’s made for shooting with iron sights, and it’s very good at what it does. That said, you can always mount a red dot on your receiver if you want to play with optics.
Pros:

The Midwest Industries AR-15 Combat Handguard is a free floating forend that mounts on your barrel nut.

The Geissele Mk13 Super Modular Rail Handguard solves the issue of gas block clearance by including one in the kit.

Key features:
- 2-piece drop-in design
- Barrel-width inside diameter
- 12 inches long
- Colt replacement lookalike
The D.S. Arms C.A.R. Handguard Set is designed to look just like the original Colt handguard. It’s sized for older A1/A2/A4 rifles, but not the newer M4. Installation is a breeze. Just remove the delta ring, press the two sides together over your barrel, and you’re good to go.
This is a military replica, so it’s designed for rifle-length gas systems. While it looks like an original Colt, we should point out that it’s not nearly as well constructed. D.S. Arms used nylon instead of polymer, and the aluminum heat shield is fairly flimsy.

- Fits older A1/A2/A4 rifles
- Classic Colt look

- Hybrid Picatinny/M-LOK rails on sides and bottom
- 4 quick-detach sling swivel mounts
- Includes proprietary barrel nut and installation wrench
The Knight’s Armament URX III is a free floating handguard with a unique quad rail. The top Picatinny rail is full-length, but the sides and bottom feature short, 5-slot rails at the front and back, with M-LOK mounting points between them. This allows you to attach tactical accessories, while foregoing the added weight from the – usually unused – middle section of the rail.

- 1.35-inch inside diameter
- Top Picatinny rail
- Available in 12 and 15-inch lengths
- 3 rows of KeyMod attachment points
- 2 quick-detach sling mounts
- Includes barrel nut and installation wrench
The Seekins Precision NOXS Handguard is engineered to be as slim as possible. It’s only 1.5 inches in diameter, which is a good size for smaller hands. The inside diameter of 1.35 inches isn’t the smallest we’ve seen by any means, but it’s still too small for some gas blocks. Make sure to measure yours before you order.
This handguard comes with a barrel nut and installation wrench, so you won’t need to buy any extra hardware to get it installed. It features a full-length Picatinny top rail, and KeyMod attachment points along the sides and bottom. There are also a pair of quick-detach sling mounts on either side.

Bottom Line
Wow! That’s a lot of variety.
Before we finish, we should talk about what makes a free float handguard different from a drop-in version. A drop-in handguard physically holds your barrel, while a free floating handguard simply surrounds it and provides a grip.
This only really matters if you’re firing your rifle with a sling or a bipod. In those cases, a drop-in handguard can cause the barrel to flex, affecting your accuracy. Since a free floating handguard doesn’t touch the barrel, your accuracy remains unaffected while firing from a bipod or a sling.
Other than that, which AR-15 handguard is the best is a matter of personal preference. How much accessory space you need, what type of grip is most comfortable, and how much time you want to spend building your rifle are questions that only you can answer.
We like to think we chose enough of the best AR 15 handguards to meet just about anyone’s needs. But even if you decided to go a different direction, we hope you learned something today.
