20 Inch AR-15: The Ultimate Rifle for Shooting Enthusiasts

If you're looking to own a rifle that is reliable, powerful, and customizable, the 20 inch AR-15 is an excellent choice. The AR-15 is known for its versatility and has been used by military personnel as well as civilian shooters. However, not all AR-15s are equal. In this article, we'll discuss why the 20 inch barrel length makes it stand out from other rifles in its category.

Benefits of a 20 Inch Barrel Length

The barrel length of a rifle plays an important role in determining accuracy and range. A longer barrel allows for better velocity which results in greater range and improved accuracy at longer distances.

Additionally, with a longer barrel you can create more torque on the bullet which leads to better ballistics performance due to increased spin stabilization. This also leads to less deviation when shooting over long distances or against strong winds.

Moreover, having more distance between your hands offers improved balance since there's less weight concentrated towards your grip area compared with shorter barrels where weight distribution tends towards the rear end of the weapon resulting in imbalance issues during extended use or rapid fire situations.

Comparison Between Other Barrel Lengths

When comparing different types of rifles chambered for .223/5.56mm ammunition cartridges such as M16A2 (with its standard issue 20-inch chrome lined bore), M4 carbines or shorter barreled versions like SBRs (short barreled rifles) or even pistols; each configuration has pros & cons depending on your use case scenario:

Short Barrels vs Long Barrels

Shorter barrels provide ease-of-use advantages like compactness making them suitable options if you're working within very tight spaces such as vehicle transportation due to their smaller form factor but they sacrifice velocity leading sometimes poor ballistics performance compared with their larger counterparts plus they have reduced accuracy over long distances.

On the other hand, a longer barrel like the 20 inch AR-15 provides greater range, more torque on bullet spin for improved stabilization and better ballistics performance at extended ranges. The disadvantages of these rifles are weight distribution (they tend to be front heavy), overall size & length which can make them cumbersome to handle in tight spaces or when rapid movement is needed.

Mid-Length vs Rifle-Length Gas Systems

A gas system sends hot gases generated by gunpowder ignition back down the barrel so that another round can be chambered and fired. Mid-length gas systems offer less recoil than Carbine length due to having more distance between where it's tapped off from near muzzle crown compared with shorter carbine versions but this comes at expense of being less reliable under stress conditions such as prolonged firing sessions or exposure to extreme temperature environments because there's always some sort of residual gas buildup around piston rings causing increased stress on internal parts like bolt carrier groups leading sometimes malfunctions in operation especially if not maintained properly.

Rifle-length systems offer even smoother cycling and less felt recoil because they have longer distance between channels where pressure build-up occurs within bore allowing for cooler temps before returning back into action cycle pathway; however it requires even larger buffer tube assembly setup resulting in heavier weight making them sometimes impractical compared with mid-length counterparts depending upon your preferences.

Customization Options For Your 20 Inch AR-15

One of the key features that makes the AR-15 stand out is its customization options. This allows shooters to tailor their rifle based on their specific needs whether you're an experienced marksman or just starting out.

Some popular modifications include:

  • Optics – adding scopes, red dots or holographic sights for improved targeting.
  • Grips – customizing your grip style can help improve comfort during long shooting sessions.
  • Stocks – adjustable stocks allow users greater flexibility in finding a comfortable shooting position.
  • Trigger – upgrading to a custom trigger can lead to improved accuracy and smoother operation.


In conclusion, if you're looking for a rifle that is reliable, customizable, and powerful then the 20 inch AR-15 is an excellent choice. Its longer barrel provides greater range and improved accuracy at longer distances while customization options allow you to tailor your rifle based on your specific needs. Whether you're an experienced shooter or just starting out, the 20 inch AR-15 remains as one of the most versatile rifles available in today's market.


What is a 20 inch AR-15?

A 20-inch AR-15 is a type of rifle that has a barrel length of 20 inches. It is often used for long-range shooting and hunting. The AR-15 platform, initially designed by ArmaLite in the late 1950s, has become one of the most popular rifle platforms globally due to its reliability, accuracy and ease of customization.

The standard length for an AR-15 barrel ranges from about sixteen to twenty-four inches. The longer barrels are used mainly for marksmanship purposes as they deliver better accuracy at greater distances compared to shorter barrels.

A typical .223 or 5.56mm round fired from an M16/AR-15 travels around approximately two thousand seven hundred feet per second (2,700 ft/s) with little recoil due to the gas system and buffer assembly design. With this speed and precision together with its lightweight construction materials, it makes it ideal for many applications such as home defense, recreational shooting sports like target-shooting or plinking cans & bottles in your backyard.

What are some advantages of using a 20 inch ar-15?

One significant benefit associated with using a twenty-inch ar-15 is that it allows you to shoot accurately at longer ranges without having any significant deviation in bullet trajectory caused by factors such as air resistance which causes bullet drop over distance travelled.

Additionally ,the more extended sight radius provided by this configuration means you can have improved aiming capabilities even when shooting targets beyond three hundred yards away since longer barrel lengths generate higher velocity levels translating into increased kinetic energy transfer upon impact leading to higher lethality rates too.

Moreover,the larger sight radius also provides excellent clearance between your hands during reloading or malfunction clearing drills which creates less interference compared against shorter barreled rifles while providing more leverage on charging handles if modified accordingly so they don't get caught up on any obstructions encountered during operations.

What is the best scope for a 20 inch ar-15?

Choosing the best scope for your twenty-inch ar-15 mainly depends on what you intend to use it for. If you're looking to shoot long-range targets, then there are specific scopes tailored towards that application.

For example, if you want to use your rifle as an all-purpose hunting rifle, then consider having a magnified optic with variable power (2×7 or 3×9) which allows ease of acquisition and quick target identification at ranges exceeding two hundred meters.

Other considerations when choosing optics include durability factors such as water resistance ratings and shockproofing capabilities since these are critical features in any weather or terrain conditions encountered plus ensure zero hold over time even through rough handling and transportation practices faced during deployments.

How accurate is a 20 inch AR-15?

Accuracy levels vary depending on various factors. However, A well-built twenty-inch ar barrel can achieve sub-moa accuracy levels (Minute Of Angle); this translates into shooting groups less than one inch in diameter at one hundred yards providing ideal conditions like no wind effects & using premium ammunition.

The gun's accuracy also depends on the shooter's skillset; having proper breathing techniques coupled with steady hands while aiming ensures consistent shot groupings which aid towards improving overall marksmanship proficiency regardless of equipment being used.

What calibers can be used with a 20 inch AR-15?

A standard twenty-inch barrel configuration accommodates .223 Remington/5.56mm NATO rounds due to similarities in cartridge dimensions ensuring compatibility across varying magazine types available today; however there exist other options worth exploring such as adding short stroke piston systems combined chamber adapters allowing interchangeable firing between different calibers ranging from .300 Blackout all the way up through .458 SOCOM.

It’s important when switching from one caliber type or another that proper cleaning and maintenance practices should be adhered too so as to avoid any associated malfunctions caused when accumulated debris or grime build up and create blockages within the barrel or gas system.
