.300 Blackout Barrels
Since it hit the market, the AR-15 has been popular because of its versatility, efficiency and easy customization. You can build your firearm from scratch or customize an AR-15 base model to create any style of gun you need.
With a .300 Blackout barrel, you can configure your AR-15 to fire the unique .300 Blackout rounds, which offer powerful, accurate performance and an even greater array of options to meet your needs as a shooter.
.300 Blackout Advantages
An AR-15 set up for .300 Blackout is arguably one of the most versatile builds available. Converting your firearm is as easy as swapping your current barrel for a high-quality .300 BLK barrel or choosing a complete Blackout upper for easy changeovers in the field. Make these small changes and you're left with a totally new firearm with even more capabilities.
The .300 Blackout carries a .30-caliber bullet that offers greater mass than a .223 Remington's .22-caliber projectile. Though these bullets are delivered at a lower velocity, the .300 Blackout's lower chamber pressure and fast-burning powder allow for shorter, lighter barrels ideal for close combat.
The .300 Blackout cartridge is available with a wide range of projectiles, allowing you to select and fire whichever is best for a given occasion. Your AR-15 with a Blackout barrel is able to safely discharge any of the .300 BLK ammunition out there without modification, including both super and subsonic ammunition.
History and Inception of the .300 BLK
In 2009, the U.S. military contracted Advanced Armament Corporation (AAC) to create a quiet new cartridge that would replace the MP5SD as the Spec-Ops weapon of choice. This new ammunition was intended for use in closer quarters and needed to deliver more power than its predecessors while remaining compatible with the M4/AR-15 platform.
The .300 Blackout uses virtually the same case as the 5.56 shell, but the case is necked up to accept a .30-caliber bullet and then trimmed to the correct length.
AAC began by looking at the previously developed .300 Whisper cartridge and reengineered it to increase its reliability, accuracy and performance. The resulting .300 Blackout cartridge was officially approved in 2011 and has steadily gained popularity in the years since, becoming one of the best-loved cartridges for both military and civilian use.
.300 Blackout Barrel FAQ
How to choose the right .300 Blackout barrel
The key to choosing the right .300 BLK barrel for your firearm is to start by deciding how you want to use that gun. If you plan to use your .300 Blackout AR-15 for shorter distances or home defense, you should choose a shorter, lighter barrel. A longer barrel with a heavy profile will provide better accuracy for long-distance shooting. Also, keep the twist rate in mind to ensure the barrel you buy will fit your applications — some twists are more geared for either supersonic or subsonic ammo.
Beyond barrel length, one of the most important factors for selecting the best Blackout barrel for your AR-15 is choosing a high-quality product. Look for barrels from reputable manufacturers and check out the product reviews.
What can I use the .300 Blackout for?
The .300 Blackout offers versatility for all kinds of firearm enthusiasts, from military personnel to competition shooters. AR-15s set up for .300 Blackout can handle projectiles with weights ranging from 110 grains to 220 grains.
Blackout rounds are a particularly popular choice for hunting because they offer considerable power and frontal area, allowing you to make an ethical kill at ranges up to about 200 yards. They're also popular for home defense since the larger bullets and lower velocities reduce the risk of overpenetration.
