AR 15 20 Inch Barrel: The Ultimate Guide

If you're looking for a rifle that can deliver accuracy, power, and versatility, the AR-15 is a great choice. And if you want to maximize its performance potential even further, choosing the right barrel is crucial. In this comprehensive guide, we'll take an in-depth look at everything there is to know about AR-15 20 inch barrels.

What Is an AR-15 Barrel?

Before we dive into the specifics of a 20 inch barrel for your AR-15 rifle, let's first understand what exactly an AR-15 barrel is. Simply put, it's the long metal tube that guides and directs the bullet as it exits through the muzzle of your rifle. It also houses other important components such as gas systems and handguards.

Why Choose a 20 Inch Barrel?

There are many different lengths available when it comes to choosing an AR-15 barrel – so why choose one that measures specifically at twenty inches long?

Firstly – velocity. Generally speaking longer barrels allow for more complete combustion of gunpowder which translates into higher muzzle velocities; This means you can achieve better range with heavier bullets out past 600 yards or so by using a longer length (when compared with shorter options.). Although this may not be too important if hunting within closer ranges.

Secondly – accuracy: Longer barrels give greater sight radius between front & rear sights which will increase precision/accuracy on targets smaller than self defense applications; However accuracy should always be achieved through good fundamentals rather than simply buying certain types parts!

Lastly – aesthetics: Some people just prefer how rifles look with specific lengths of barrels!

Comparing Different Types Of Barrels

Let's compare two popular types here:

Stainless Steel Barrels

These are often used in competition shooting due to their increased durability over time compared against regular steel versions which may rust. They are also lighter than the alternative and thus offer greater maneuverability.

Chrome Moly Barrels

These types of barrels are generally less expensive than stainless steel versions. Chrome moly is a type of steel that has been treated with chromium and molybdenum, which improves its durability against high heat applications.

Benefits Of A 20 Inch Barrel For AR-15

We've already touched on some benefits available when using longer barrel lengths like increased accuracy, velocity & sight radius. There's more where that came from though!

A 20 inch barrel can be seen as a kind of "sweet spot" length when compared to other options such as shorter 16-inch barrels or significantly longer options (22 inches+). By choosing an AR-15 with this length barrel – you're getting optimal performance without sacrificing too much in terms of weight or portability – making it great for hunting trips where carrying things over long distances may be required!

Another benefit worth mentioning lies in the effective range offered by this length; It allows shooters to engage targets at ranges beyond what would normally be possible with shorter barrels (i.e., past distances ranging typically between 500-600 yards).

Tips On Using Your AR-15 With A 20 Inch Barrel

To get the most out of your rifle, here are some useful tips to consider:

  • Use higher-quality ammunition for better performance
  • Clean your rifle regularly, especially after use during wet conditions.
  • Keep up maintenance on any moving parts such as gas system components.
  • Always follow safety protocols while handling firearms.


Choosing an appropriate-length barrel for your AR-15 is important if you want optimal performance from it! The twenty inch option offers numerous benefits over others available today – including improved accuracy & velocity potential without sacrificing too much weight/portability factors — but there really isn't one-size-fits-all solution so choose wisely. With the tips included above, you should have a solid understanding of what to look out for when purchasing and using an AR-15 barrel at this length!


What is an AR 15 with a 20 inch barrel?

An AR-15 with a 20-inch barrel is a semi-automatic rifle that has been designed and manufactured to meet the requirements of many different types of users, including hunters, sports shooters, and law enforcement agencies. It's important to note that the length of the barrel can vary depending on specific models. The advantage of having a longer barrel like this one is that it allows for greater accuracy at longer ranges. This type of rifle also has the ability to shoot multiple rounds in quick succession by using detachable magazines.

The AR-15 platform itself was developed in the late 1950s as an intermediate cartridge system for military use and became popular among civilians due to its reliability, customizability, ease-of-use, and durability.

With advances in technology over time allowing manufacturers to create new materials with lighter weights but maintain structural integrity; there have been several variations on this design since then which include different barrels lengths ranging from 16 inches up through as long as 24 inches or more.

What are some advantages/disadvantages of using an AR-15 with a 20-inch Barrel?

One major advantage of using an AR-15 with a twenty inch barrel would be increased accuracy at longer distances owing primarily due to two factors: first being improved sight radius which makes aiming easier when shooting targets beyond distances achievable by shorter-barreled models and secondly because longer barrels tend not only reduce muzzle flash (which can affect your vision while aiming), but also cause gases from firing/expulsion process inside themself-contained within their respective housing during discharge thus providing additional stability leading up-to follow-up shots being made more quickly after each shot fired without losing target acquisition effectiveness too much between shots taken

On other hand disadvantage could be portability issues where most people who need rifles for self-defense or hunting prefer shorter-barrel options like those offered by carbine-length models. The additional weight can also be a factor, especially for those who plan on carrying their rifle around for extended periods of time.

What is the effective range of an AR-15 with a 20-inch barrel?

The effective range of an AR-15 with a 20-inch barrel varies depending on multiple factors such as ammunition type, shooter ability, weather conditions and the particular model used. Generally speaking, however; most users can achieve accurate shots out to about 600 yards or so when using appropriate match-grade ammunition loaded specifically designed to work well within this platform.

However It's important to note that ranges exceeding these distances are possible under ideal circumstances but become significantly more difficult without proper optics or other aids which help stabilise aim etc., properly mounting accessories like scopes and other types of sighting equipment will increase overall accuracy from longer distances while still retaining portability necessary for dynamic shooting applications like hunting or competition shooting events

Are there any legal restrictions on owning/using an AR-15 with a 20 inch Barrel in the USA?

In addition you should be aware that certain cities and municipalities may restrict possession/usage even further beyond what federal/state law says currently (and laws change frequently), so consulting with local authorities before making purchases should always be done beforehand especially if planning use outside your private property as both state/local penalties could impact you adversely if caught violating said rules/regulations

How do I maintain/clean my AR-15 with a 20 inch Barrel?

Proper maintenance procedures vary depending upon individual requirements however basic steps include regular cleaning of the barrel (with solvent), lubrication of moving parts and a thorough inspection for damage or excessive wear and tear. It is always important to follow manufacturer's recommendations regarding maintenance schedule/maintenance kits available in order to ensure that your firearm stays fully operational at all times.

It’s also worth noting that some shooters prefer using bore snakes designed specifically for cleaning rifled barrels, which offer an easier/quicker method of performing this essential task especially when out hunting or participating in other types shooting events where time may be limited, it’s advisable to carry these with you so you can perform quick cleaning maintenance after each use which will keep your firearm clean – free from dirt/grime buildup residue etc., thus helping prevent malfunctions when it counts most.
