Things You Need to Know Before Buying an AR 15 Handguard

AR 15 HandguardAs you may be aware, the AR 15 is one of the best firearms for hunting and home security. While this is the case, you may need to upgrade several aspects of this guide to improve its accuracy and ease of use.  One of the commonest AR 15 upgrades is a handguard.

Adding the right handguard to your gun is important, but will definitely add some weight to your gun.

Since you do not want your gun to be bulky and heavy, it is advisable to only go for the lightweight AR 15 handguards in the market. At first, this may appear to be a relatively easy choice. However, it is not all that straightforward.

In addition to the weight, there are several other aspects you need to consider before making this choice. Discussed below are some of the main considerations you need to make while shopping for the best lightweight handguards for the AR 15:

1. Weight

Since you are looking for a lightweight option, it is obvious that weight is going to be a key consideration in this choice. Basically, all the available handguards will add some weight to your AR 15. So, by how much will your preferred handguard add to the weight of your gun?

The weight of these components will mainly depend on the materials they are made of. Most of the affordable hand guards for AR 15 are made of steel. While the material is known to be very durable, such products are the heaviest.

Handguards made of aluminum are lighter than steel handguards, but not as light as the polymer and composite based handguards available today. If you are a bench rest shooter, weight should not be a problem. However, you need to go for the lighter products, if you will be carrying your gun along with you from time to time.

2. Mounting Options

Another aspect that will be important in this selection is the type of mounting offered by your preferred handguard. The various products available today offer different mounting options. When choosing the right one, these are the options you should consider:

  • Rings
  • Weaver rails
  • Picatinny rails

While none of these options is superior to the other, each of them has its own benefits as well as downfalls. While trying to find out the right mounting system for your gun, you need to consider the accessories you would like to add to the firearm. For instance, gun accessories that are compatible with weaver rails are also compatible with Picatinny rail.

However, the accessories designed for attachment on Picatinny rails may not be compatible with weaver rails. Handguards with picatinny rails are very durable, but are comparatively heavy weight. As such, the choice of the right mounting option will mainly depend on your individual preferences.

3. Accuracy

Basically, the right handguard will enhance the safety of the gun and allow you to attach mode accessories to the gun. However, there is not point of buying a product that does not improve the accuracy of your AR 15, right? As you may have realized, there are only two main types of AR 15 hand guards available today:

  • Free-floating Handguards
  • Drop-in Handguards

The main difference between these two is that the handguard is not in contact with the barrel in the free-floating handguards. Contrary to these, the drop-in handguards are in contact with the barrel. The fact that the free-floating units are not in contact with the barrel makes them more accurate.

Since they do not touch the barrel, such handguards will not interfere with the various barrel harmonics, such as grip, recoil or bipod. The drop-in handguards, on the other hand, affect barrel harmonics because they are in actual contact with the barrel. This may cause the barrel to bend thus affecting the accuracy of the gun.

This being the case, the best free-floating handguards are comparatively costlier than the drop-in options. The free-floating models are recommended for sniper rifles and for competition applications.

4. Length

This is another thing you need to think about before buying a handguard for your rifle. Basically, your choice of handguard length should be influenced by the length of the gas system on your gun. However, several other factors will also affect your choice. For instance, a longer handguard will offer you a larger grip area.

This is particularly beneficial for users with large hands. A longer handguard will also give you more mounting space for accessories. With a longer handguard, you will also have a larger surface area for cooling.

If you would like to buy a guard that is longer than the gas system on your gun, you should consider buying a free-floating model. This is particularly the case if your gun uses a low-profile gas block.

5. Heat Resistance

Handguards are mainly installed to offer heat resistance for the gun. As such, you need to consider the heat resistance offered by the model you would like to buy. While different models have varying heat resistance, the Free-floating handguards are known to be better, in this regard.

For enhanced cooling and heat resistance, you should go for polymer products as opposed to those made of aluminum. Products with vents will also have better heat resistance and cooling properties. However, metal handguards will be the best choice for prolonged shooting.

Strongest ar 15 Handguard

Handguards are a great addition to your AR 15 rifle. With the right one, you will improve the heat resistance; get a larger grip area and more space for accessories. However, not all the available handguards are suitable for the ARs. As you have learned throughout this guide, this choice requires careful consideration of several aspects.

In addition to the weight, you should also consider the length, heat resistance, accuracy, and mounting options. Regardless of the intended application, this guide will help you choose the best lightweight AR 15 handguard.
