Top 7 Best AR-15 Handguards (Free Float & Drop-in) – Top Selections in 2020

With so many of them on the market, we understand that finding the best AR-15 handguard to best fit your rifle is tough. Luckily for you, we have done the difficult part and have shortlisted and chosen some of the best handguards you can get for your AR-15.

Factors to Consider when Purchasing an AR-15 Handguard

Getting a handguard for your AR-15 may depend on personal preference. However, there are several factors that should still play a key role in your overall decision process. Here are the few things you’ll need to consider before signing that check.

The Intention: To Use Front Sight Block

Before we dive straight into handguards, we need to first look into your AR-15’s gas system. Traditional M4s and AR-15s come with a fixed front sight gas block, this means that your front sight and gas block are all connected. These types of rifles also usually come with a delta ring assembly for an easier installation of drop-in handguards.

Having a front sight gas block will limit the length of the handguard you can install and often also make it difficult or impossible to install a free-floating handguard. The presence of the front sight gas block will likely obstruct your view when using an optic such as a red dot.

Considering the fact that most shooters prefer to use some sort of optic these days, it is recommended to go for a low-profile gas block instead of the front sight gas block.

With all the disadvantages discussed above, you may be wondering why are there still holdouts with front sight base? One valid reason for having them is because the front sight base is more reliable compared to back-up sights and is always there should your optic fail.

That being said, modern back-up sights have also come a long way with better battery life the reliability for red dots.


The AR-15 handguard comes in three popular looks and they are military, tactical, and classic. You will then need to check what type of look will best suit your rifle or which one do you prefer best? The look may or may not matter to some, but if it does, be sure to get one that suits your rifle’s overall design.

Free Floating vs Drop-In

Any forces you have against your barrel can affect the accuracy of your shots – something that gets much more noticeable as the distances increase. Traditional drop-in handguards make contact with your barrel, meaning just be simply gripping, resting it, or attaching accessories to your handguard can affect your rifle’s accuracy.

This issue can be eliminated with the use of free-floating handguards. As the name suggests, they’re free of contact from your barrel as it “floats” from your upper receiver to the end of the handguard.

Longer free float handguards even let you rest your handguard on a surface when shooting, instead of resting your barrel directly. This is yet another feature that helps you keep your accuracy from suffering as a result of something pushing against the barrel. Another great thing about free-floating handguards is that since it is further away from the barrel, it offers better ventilation to help you reduce the heat absorbed.

To make it easier for you, below is a list of pros and cons for both drop-ins and free-floating handguards.

Drop-In Handguards

  1. Easy to install
  2. Cheaper
  3. Lighter
  1. Worse accuracy
  2. Shorter/Less mounting and grip space
  3. Less attractive
  4. Absorbs more heat

Free Float Handguard

  1. Improves accuracy by avoiding contact with the barrel
  2. Absorbs less heat
  3. Provides more room and mounting points for accessories
  4. Looks more attractive
  1. More expensive
  2. Weigh more
  3. Difficult to install

Handguard Length

When it comes to the length of your handguard, generally, longer is better until you reach the maximum distance where you can comfortably reach. Longer handguards will allow you to grip further down the rifle that prevents you from potentially touching a hot barrel. The longer length also gives you more mounting space for accessories.

The major downside to having longer handguards are the increased weight and the fact that they put more weight towards the front of your rifle. However, despite the added weight, many still prefer to get a slightly longer handguard whenever possible.

Mounting Options

If you plan to mount accessories such as M-Lok or KeyMod onto your handguard, you’ll need to make sure to get one with additional slots for each accessory. Getting a handguard that allows you to mount accessories means you have that extra flexibility to bring along a few other nifty parts that will improve your overall shooting experience, such as a scope.

Handguard Materials


Most free float handguards are made from 6061-T6 aluminum. These are slightly weaker compared to the 7075-T6 material. But this doesn’t mean that the 6061-T6 is a bad choice, it is still more than durable enough a low-stress part of the rifle, such as the handguard.

Carbon Fiber

For those with the extra cash to spend, getting a handguard made from carbon fiber is a stronger yet lighter alternative. Carbon fiber also does a better job of resisting heat absorption compared to aluminum. However, be prepared to see the huge difference in price.


The polymer is yet another common material found in handguards. The polymer material is often used with an aluminum heat shield for drop-in handguards. While it is lighter than aluminum, it may not be secure enough for mounting accessories.
