But don’t worry. Keep reading because we’ve put together a roundup of some of the best AR-15 upgrades and modifications for enthusiasts like you. From accuracy enhancements to functional add-ons, we’ve got you covered.

Why Upgrade the AR-15?

Whether you’re a seasoned marksman or a first-time shooter, there are plenty of reasons to upgrade your AR-15. Maybe you want to improve accuracy for long-range shooting or extend the functionality of your rifle.

Or perhaps you’re simply looking to add a little bit of style to your gun with some new furniture.

Whatever the reason, there are endless possibilities when it comes to upgrading and modifying an AR-15.

Best AR-15 Upgrades

There are many options when it comes to AR-15 upgrades. Let’s look at them now.

Accuracy Upgrades

One of the most popular reasons for upgrading an AR-15 is to improve accuracy. If you’re looking to add a little more precision to your shots, there are a few different routes you can go.

Free-Float Handguards

When it comes to choosing a handguard for your AR-15, there are a few things to consider. One option is to install a free-float handguard.

Free-float handguards attach directly to the barrel of the gun, rather than the front sight base like most standard handguards. This results in a more stable platform for the barrel, which can lead to increased accuracy.

Additionally, free-float handguards usually provide more space for mounting accessories, such as optics or bipods. However, they also tend to be more expensive than standard handguards.

Ultimately, it’s up to you to decide what is best for your needs. But whether you choose a free-float or standard handguard, make sure to pick one that is high quality and will withstand years of use.


Making accurate shots is one of the most important aspects of marksmanship, and several factors can affect your ability to hit your target. One way to improve your accuracy is by upgrading the trigger on your rifle.

The AR-15 has a pretty good factory trigger, but there is always room for improvement. A quality aftermarket trigger will have a lighter and smoother pull, which can help you make more precise shots.

In addition, a good trigger will have a crisp breakpoint, which can help you to avoid gun movement as you squeeze the trigger. By upgrading to a quality aftermarket trigger, you can take your shooting to the next level.


When you buy a gun, the stock is an important part of the package. The stock is the part of the gun that you rest against your shoulder, and it plays a major role in accuracy and comfort.

Many gun manufacturers offer stocks in a variety of styles, and many shooters like to upgrade to an adjustable or collapsible model.

This can help you find the perfect fit for your shooting style, and make it more comfortable to shoot for long periods. In addition, adjustable stocks offer the added benefit of being able to adjust the length of pull.

This is the distance from the trigger to the end of the stock, and it can be crucial for comfort and control.

Whether you’re looking for a better fit or more adjustability, upgrading your stock is a great way to improve your shooting experience.

Functionality Upgrades

In addition to accuracy upgrades, many modifications can extend the functionality of your AR-15. Let’s look at them now:


When it comes to adding optics to a firearm, there are a variety of options to choose from. One popular option is to add a red dot sight or another type of optic.

This can help you acquire targets more quickly and shoot more accurately, especially at longer ranges.

There are many different brands and models of red dot sights on the market, so it is important to do your research to find the one that best suits your needs.

In addition to red dot sights, there are also several other types of optics that can be added to a firearm, such as scopes and night vision devices.

No matter what type of optic you choose, it is important to get professional help to ensure that it is properly mounted and calibrated. With the right optic, you can take your shooting skills to the next level.


If you’re serious about marksmanship, then you know that a bipod can be a valuable addition to your gun. Bipods attach to the bottom of the gun and provide a stable platform for long-range or precision shooting.

This can be extremely helpful if you’re trying to take a shot at a distance, or if you need to take a shot with pinpoint accuracy. There are many different types of bipods available on the market, so you can find one that fits your needs.

Whether you’re looking for a simple bipod for target practice or a more heavy-duty model for hunting, there’s sure to be a bipod that’s perfect for you.

So don’t wait any longer, get yourself a bipod and start enjoying the benefits of stable shooting today.


A foregrip is a great way to improve your control of the gun, especially when shooting rapidly. There are many different styles of foregrips to choose from, so you can find one that fits your shooting style.

For example, if you have large hands, you might want to consider a finger groove foregrip. This type of grip provides additional support for your fingers, helping to prevent them from slipping when you’re shooting.

Alternatively, if you’re looking for a more traditional grip, some foregrips fit over the barrel of the gun. Whichever style you choose, a foregrip is an essential part of any gun accessories arsenal.

Aesthetics Upgrades

Finally, many upgrades simply add to the aesthetics of your AR-15. They are as follows.


One popular option is to upgrade the furniture on your gun. This includes the stock, grips, and handguards. You can find furniture in a variety of colors and materials to give your gun a unique look.


Another way to customize the look of your AR-15 is by installing a new barrel. Barrels come in a variety of lengths and finishes, so you can find one that matches your style.

Best AR-15 Parts and Accessories

Like upgrades, many accessories can upgrade your AR-15. Take a look below for the accessories you can get.


One useful accessory is a sling. Slings allow you to carry your gun hands-free, which can be helpful when hiking or hunting. There are many different types of slings available, so you can find one that fits your needs.


Another popular accessory is a flashlight. This can be helpful for illuminating targets in low-light conditions. Many flashlights also come with a mounting system, so you can attach them to your gun for easy access.


As we mentioned before, an optic can be a great addition to your AR-15. Optics can help you acquire targets quickly and shoot more accurately. There are many different types of optics available, so you can find one that fits your needs.


In addition to an optic, you might also want to add some backup iron sights. This can be helpful if your optic fails or if you need to shoot at close range.


Grips can help you maintain control of your gun, especially when shooting rapidly. There are many different styles of grips to choose from, so you can find one that fits your shooting style.


Rails allow you to attach accessories to your guns, such as a flashlight or grip. This can be helpful for customization and making your gun more versatile.


Lights can be attached to your gun to help you see in low-light conditions. Many lights also come with a mounting system, so you can attach them to your gun for easy access.

Muzzle Brake

An Aero Precision muzzle brake can be attached to the end of your gun to help reduce recoil. This can help make follow-up shots more accurate.


A suppressor can be attached to the end of your gun to help reduce noise. This can be helpful for hunting or shooting in populated areas.
