Best 300 Blackout Rifles: Our Top Picks For Long Range Accuracy

When the military created the 300 Blackout firearm platform, little did they know this design would become an extremely popular option for civilian gun enthusiasts. The ability to increase your firepower for long range hunting and target purposes in a lightweight, semi-automatic option makes it an impressive gun to own. 

Practically perfect for home defense as well, it is an increasingly sought after choice due to easy maneuverability, and just how much fun it is to shoot. This also means there are quite a few available models in the gun industry, and in order to help you to find a quality pick- we’ve narrowed down some of the best 300 Blackout Rifles for you to consider. 

Here’s A Quick Look of Our 7 Best 300 Blackout Rifles

What Makes a 300 Blackout Rifle a Popular Platform

300 Blackout Rifle

Originally created for close quarter battle, these were designed for power, accuracy, and maneuverability- something every gun enthusiast wants in their choice of firearm. The 300 BLK is the hat trick of rifle weaponry, and has all you need for a wide variety of uses. It even is easily converted to a pistol configuration with a shortened barrel. They are an ideal choice for hunting, plinking, and home defense. 

The modified 3.56 shell for a .30 caliber ammunition it takes means it allows for a huge range of reloader and budget conscious shooter to avoid a “new” caliber platform. They accept the highly reliable magazines from the AR platform to avoid the expense of new hardware as well. In fact, almost everything from an AR-15 is compatible, allowing you to completely customize your own weapon build. 

You get more velocity and mass, without a huge change in recoil despite being able to use both subsonic and supersonic loads (with slight power tradeoffs concerning gas function). This means you get a lot more power without the wear and tear on your weapon. 

Hunting Benefits

As mentioned, the platform was originally designed for close range combat, and although many people will argue it is still best used for close range targets- the many improvements through the years has made it much more versatile.

The .300 Blackout cartridge is a full-spectrum cartridge with the ability to launch up to 2800 fps (feet per second) and is still accurate at 500 to 600 yards. The fact that the round was created around subsonic suppression also means you can shoot without having to worry about ear protection (which is great for long days on the range). 

Another benefit is how the elongated profile of the round is designed to feed from AR magazines. This allows you to shoot unsuppressed for an easy on the shoulder, easy on the ear, but seriously hard on your target shot. The bottom line is, the power behind them stems from the adaptation of a pistol round for a rifle design, making them incredibly unique- even down to the powder used

Home Defense Benefits 

Because it was originally created for short range firing, the 300 BLK still holds amazing attributes for this purpose. As a home defense option it truly is the choice you need. Many will argue the sound of a round being racked into an old fashioned shotgun is enough to send home invaders scrambling. And even though this is definitely an excellent option, if you want a second choice, the lightweight maneuverability and powerful accuracy of a .300 Blackout round allows for one handed action when needed and a semi-automatic load for quicker firing times. 

Distinguishing the Rifle from the Pistol Configuration

When you first started considering a 300 BLK you may have been curious about the differences between the rifle and pistol platforms. After all, at first glance they look remarkably similar, minus one attribute: the barrel length. The barrel length of a rifle is defined as at least 16 inches, and you will find most options have a barrel measuring 16.1 inches exactly. Pistols have a barrel 10.5 inches or shorter, and do not have a permanent buttstock to keep it from being classified as a SBR (short barrel rifle) and thus being subject to the $200 SBR tax. 

What to Consider When Buying a 300 Blackout Rifle

One of the first things you need to think about prior to purchasing a 300 Blackout is why you prefer this particular platform. If you already own an AR-15, it might be more affordable to consider 300 Blackout barrel conversions that provides you the ability of shooting a .300 round as a 2 guns in 1 scenario. 

But if you truly want a standalone 300 option, you have the choices between pistol and rifle barrel length designs. As mentioned above, rifles are more popular with hunting and home defense, although pistols can also do the same. They simply don’t have the same overall range a rifle does. 

Gas Systems

Gas systems are generally matched with the length of your barrel to provide the best function without too little, or too much, pressure. In general a 300 Blackout with a 16 inch barrel will have a carbine gas system. This means it is ideal for 10 to 18 inch barrels and has a port at 7 inches- almost to the middle of the range, which is ideal for less recoil and wear. 

Customized builds may use a longer system, such a mid length, or even rifle, but too little barrel length after the gas port can result in poor gas flow and cause issues with cycling. For the most part you will find a rifle equipped with a carbine system, although occasionally a pistol (smaller) system may be present. In this situation you may find you have excessive recoil and wear. If you plan on switching out barrel lengths with the longer gas systems, buffers exist to lighten the kickback. 

Price Range

One thing you may notice is the 300 platform comes in a wide price range to fit an array of budgets. Obviously material use, such as cold forged metals and various stock finishes can raise the overall cost of the rifle, but that doesn’t mean less expensive options aren’t of a dependable quality. 

There is a surprising selection of top notch builds and included features for a fraction of what high end options cost, so don’t always assume the higher price tag is the better choice for you.
