The Best AR-15 Handguards for Your Next Build in 2021

Last Updated on September 9, 2021.

The handguard on your AR-15 is more important than many shooters realize. Your handguard is more than a great spot to mount accessories and optics. It also affects the accuracy of your rifle.

AR-15 handguards of old made contact with the barrel, which changed the flex pattern of the barrel and reduced accuracy, albeit slightly.

Your handguard also protects your hand from the heat of the barrel during rapid fire. Which is obviously important.

So, using the best AR-15 handguard on your rifle is key to maximizing the performance and versatility of your rifle.

Budget AR-15 Flash Hider

Magpul is known for producing solid, (mostly) affordably priced parts. The Magpul  M-LOK Handguard is aimed squarely at the budget AR-15 builder. It does the job for an unbeatable price.

These handguards are designed to be straight over replacements for the classic M-16 two-piece handguards. Therefore, these are not free float handguards. So, there’s some impact on accuracy. But, if you’re replacing classic handguards, there’ll be no difference.

Check on OpticsPlanet

However, this handguard is an improvement over classic handguards in terms of construction and weight. Magpul built this model from high impact polymer, which is lighter and stronger than the high-density plastic of classic handguards.

Additionally, this is a one-piece design, which is more durable than the two-piece handguards.

There’s an integrated heat shield. So, these protect your hands during rapid fire.

There are M-LOK attachments points at the 12 o’clock10 o’clock2 o’clock, and 6 o’clock positions. You can mount accessories in all the most common positions. However, the mounting points aren’t as flexible as a handguard with attachment points on all sides.

The body is shaped to create a good platform for your forward handhold and allow room for overhanging attachments. Additionally, this handguard is wide enough to accommodate both direct impingement and gas piston actions.

Although this isn’t the best handguard available, it’s very capable and very affordable. It’s a great Magpul option for those who have a prebuilt rifle they want to upgrade and those who want to keep the cost of their build as low as possible.


  • Durable, one-piece construction.
  • Lighter than classic handguards.
  • Integrated heat shield.
  • Accepts direct impingement and gas piston actions.

This Double Star handguard fits any standard upper receiver, and includes a barrel nut. The installation is fast and easy.

Unfortunately, the minimalism means no attachment points for accessories or optics. So, this is best for those who only want a receiver-mounted optic.

Overall, this is a great option for those who want a lighter, more streamlined handguard, but are satisfied with the performance of their A2 handguard.


  • Free floated to improve accuracy over a standard A2 handguard.
  • Rigid platform with knurling for a solid handhold.

Check on OpticsPlanet

It’s also a free float handguard. So, you’ll get a boost to your rifle’s organic accuracy if you replace a classic handguard.

As for attachment points, there are M-LOK attachment points at the muzzle end to mount accessories. This is a good spot mounting just about anything besides a forend grip. This is by design, because the middle of this handguard is made to provide a space for a wraparound grip.

There are also two holes for quick detach sling mounts. These are handy if you like to attach the front end of your sling to the base of your handguard. They’re not in an ideal position for a three-point sling, though.

This ALG Defense handguard includes the required proprietary barrel nut. Unfortunately, no rail sections are included. Plan to purchase rail sections if you need picatinny rail space.

All in all, this is an excellent option for those who use a full grip without any forend grip attachment, but might want to use a mounted light or laser.

  • Free floated for improved accuracy over a classic handguard.
  • M-LOK attachment points in the most popular mounting location.
  • Holes for quick detach sling mounts.

In the end, these handguards are simple and prioritize retaining the look of the original M-16 A2. But, they only introduce a marginal performance increase. So, they’re best for those who want a classic look.

Best AR-15 Handguard for the Money

There are very few—if any—handguards that deliver more quality and performance for the money than STNGR handguards. That’s why the STNGR HWK is such an awesome handguard (and an awesome deal).

One thing that’s sorely missing from many handguards is some styling on the front end. For whatever reason, most manufacturers just cut the front of the handguard flat and call it good.

Check on STNGR

This handguard has a really cool cutout on the front end. It looks cool. But it also enables you to use a barrel length that leaves your muzzle device recessed into the handguard for a more flush front end, without blowing your handguard apart.

However, it might be wise to use a hand stop or a foregrip as an indexing point. Because you don’t want to put your hand around the very end of the handguard if your muzzle brake is recessed into the end of your handguard.

Aside from the styled front end, this handguard has all the durability and design features that you want.

The body is machined from 6061-T6 aluminum. And there are M-LOK slots at the 3, 6, and 9 o’clock positions. And there’s a picatinny rail along the entire spine of the handguard.

There’s also a picatinny rail section at the 6 o’clock position on the muzzle end, which is handy for mounting bipods or other accessories that require a more robust mounting system.

Lastly, there are QD sling sockets machined into the handguard at the base and at the muzzle end. And the QD sling socket at the base is nice and close to the upper receiver, for those who like to put their support hand in front of their sling point.

On last note: the barrel nut locking mechanism is quite secure. There’s a spacer with an anti-slip tab that locks into a notch on the barrel nut to guarantee that your handguard can’t slip forward. And the anti-rotation tabs are machined into the handguard body, which is a very secure anti-rotation system.

Overall, this STNGR handguard is super solid. It gives you the sort of quality that you’d usually have to pay a notably higher price to get. That’s why this is the best handguard for money, right now.


  • Good looking, but functional styling on the front end.
  • Very lightweight.
  • Excellent accessory mounting locations.
  • Integrated QD sling sockets.
  • Super secure barrel nut locking system.


  • No M-LOK slots at the diagonal positions.

Aero Precision AR-15 Atlas S-One Handguard

Versatile Handguard

Many minimal handguards do away with the top-mount picatinny rail. The Aero Precision AR-15 Atlas S-One Handguard meets the requirements of a minimalist handguard, without sacrificing any of the mounting versatility that comes with fully railed handguards.

As you’d expect, this handguard is a free float design to keep pressure off your barrel. It’s machined from 6061-T6 aluminum to provide a rigid platform for accessories and a sling.

Aero Precision also added indexing grooves in the 12 o’clock position for a more positive grip and control over your point of aim. This is ideal for anyone who uses a C-clamp or thumb forward grip.

As for attachments, the entire body is covered in Aero Taper Lock Attachment System (ATLAS). And there are picatinny rail sections at both ends of the handguard. 

So, you can attach accessories and optics almost anywhere on the rail. But, the middle, where you put your forward hand, is nice and narrow.

There are also holes for quick detach sling swivels near the receiver end of the handguard. It’s good for two-point slings. Not great for three-point slings.

Despite the slightly limited sling mount position, this Aero Precision handguard is still the best option for those who want ample attachment space, with the feel of a slimline handguard.


  • Free floated to retain your rifle’s native accuracy.
  • Indexing grooves for positive grip and muzzle control.
  • Holes for quick detach sling mounts.
  • Ample attachment points, including picatinny rail sections.
