AR-15 with 20 Inch Barrel – A Comprehensive Guide

The AR-15 is a popular rifle platform among gun enthusiasts, and for good reason. It’s versatile, customizable, and reliable. But with so many different configurations available, it can be difficult to know which setup is right for you. In this article, we’ll be exploring the benefits of an AR-15 with a 20 inch barrel.

What is an AR-15?

Before we dive into the specifics of an AR-15 with a 20 inch barrel, let’s first define what exactly an AR-15 is. The term “AR” actually stands for Armalite Rifle, which was the original manufacturer of this style of rifle in the late 1950s.

Today, however, there are countless manufacturers producing their own versions of the rifle platform. The basic design consists of a semi-automatic mechanism that fires .223/5.56mm rounds from detachable magazines.

The primary advantage to using this type of firearm is its versatility and customizability; you can modify almost every aspect to suit your specific needs or preferences.

Advantages of Using a 20 Inch Barrel

One particular configuration that has become increasingly popular in recent years is using a longer barrel length than standard (usually around 16 inches). Here are some advantages:

Increased Velocity

One primary benefit to opting for an extended length barrel on your AR-15 system (such as one measuring at least twenty inches) lies in increased velocity – particularly when using smaller caliber ammunition like .223 Remington or NATO-spec M855 rounds.

This results from two factors: firstly because more time spent under pressure means greater acceleration before leaving out – so bullets exit faster giving them higher kinetic energy levels; secondly due simply having more space within bore itself by adding another four-plus inches onto existing barrels' distance between chamber mouth end muzzle crown.

Longer Range Shots

A longer barrel also allows for more accurate and stable long range shooting. A projectile fired from a 20 inch barrel has more time to stabilize in flight before reaching its target, which can mean the difference between a hit or miss.

Improved Accuracy

In addition to improved accuracy at longer ranges, using a 20 inch AR-15 barrel can also offer better overall accuracy due to the increased rigidity of the extended length tube.

Customization Options

One of the most significant advantages with an AR-15 is customizability. You can tailor your rifle setup exactly as you like it by choosing from countless components and accessories that are available on today's market.

Some popular options include:


Adding optics such as scopes, red dots or holographic sights is an easy way to improve accuracy over iron sights.


Adding different types of grips such as "angled", "vertical" ,or "foregrip" provides shooters with greater stability & control over their weapon while firing.

Additionally there are many other customization options including but not limited too: muzzle brakes/flash hiders (which reduce recoil), adjustable stocks (for comfort), rail systems for attaching accessories like flashlights/tactical lasers/bipods etc., upgraded triggers – all things that can be added onto your already existing gun setup without having replace anything major.

Tips When Choosing Your Setup

It's important when putting together your own AR-15 system – especially if you're going for one with an extended twenty-inch barrel configuration – that you take into account what kind of purposes will be served by this firearm.

For example if hunting small game creatures then .223 Remington rounds would suffice thanks largely because they travel faster than other calibers; but if larger games (such as deer) are being targeted it might require heavier bullets which means lower velocities thus requiring some sacrifice in terms high velocity capabilities we previously mentioned.

Another important factor to consider when outfitting your rifle is weight; with an extended barrel comes added length – which in turn means increased overall firearm weight. This can have a significant impact on how well you handle the weapon, especially over longer periods of time or while moving around frequently.


In conclusion, opting for a 20 inch barrel AR-15 configuration offers some real advantages compared to other systems. Increased velocity and accuracy at range; improved stability and control due to rigid structure provided by extended length tube are just some of the key benefits that come with this setup.

Customization options further enhance versatility allowing shooters tailor experience their requirements /preferences helping ensure optimal functionality no matter what task they need perform – be it target shooting competition events or hunting game creatures down wilderness areas country's forests wildlife reserves!
