20 Inch AR Barrels

Why Choose a 20-Inch Barrel for Your AR-15? A Legacy That Endures

While the 16-inch and 10.5-inch types of AR-15 are famous today, the 20-inch AR-15 barrel is also highly valued by modern rifle shooters. Being that the design of the AR-15 was based on the 20-inch barrel, it sought a balance between reliability and performance. The tradition of using this barrel lives on among builders and shooters who put a high value on greater accuracy and ease of use. Using an AR15 with a 20 inch barrel gives you benefits that short-barreled rifles simply can’t match.

Ballistic Advantages of a 20″ Barrel

With a 20 inch barrel AR15, ballistics are performed more efficiently. When using a 20-inch barrel, .223 Rem and 5.56 NATO rounds are pushed out of the muzzle faster. Velocity with a 20-inch barrel should be up to 50-100 feet per second faster than with a 16-inch barrel. That way, you are able to shoot farther and better, which matters greatly during hunting or any defensive scenarios.

Having both a longer sight radius and extra velocity helps the 20 inch ar barrel to provide superior accuracy. Many match-grade cartridges shot through a well-crafted AR15 20 inch barrel achieve sub-minute angle groups, making it an excellent platform for long-distance precision shooters as well as small game hunters.

Enhanced Reliability and Durability

When you use a 20 inch AR 15 barrel along with a rifle-length gas system, you get one of the smoothest and most reliable functions available on all AR models. When a gas system is increased in length, the pressure required to cycle the gun reduces, taming the recoil, making the system more reliable and decreasing wear on important moving parts. So, being heavy and quick in your actions helps your gun’s recoil handling and durability of its components, especially when you fire many rounds.

AR 15 with a 20 inch barrel excels among firearms dedicated to dependability in all circumstances.

Better Handling with Lightweight Profiles

One myth is that a 20-inch barrel on an AR15 rifle necessarily results in a hefty gun. The AR-15’s autoloading, short-stroke gas-piston, and lightweight barrel design ensured exceptional agility and balance. You’ll find many different types available, such as Government-profile 20 AR barrels and fluted designs that offer weight savings and show no signs of weakness or performance droop. Just because some 20-inch configurations are heavy doesn’t mean all of them are. So if you’re worried about the heavyweight, know that modern 20-inch builds can be surprisingly agile. 

Historical & Collector Appeal

The 20” barrels are another way by which history can be preserved, and this is a significant aspect to consider. These rifles have the look and feel of their Vietnam War-era predecessors and so appeal to historical collectors. Using an AR15 with 20 inch barrel takes collectors back to the important Cold War years.
