If you're a gun enthusiast, chances are you've heard of the 300 Blackout AR-15. It's a popular rifle cartridge developed specifically for use in the AR-15 platform. But what is it exactly? In this article, we'll delve into everything there is to know about the 300 Blackout AR-15.

What Is The 300 Blackout AR-15?

The 300 Blackout (also known as .300 BLK) is essentially a shortened version of the .223 Remington cartridge used in most standard AR-15 rifles. It was designed to provide increased stopping power at short range while still being able to be fired from an AR platform.

How Does It Compare?

Compared to its cousin, the .223 Remington, which has been around since it was first introduced by Colt back in 1964 and has become one of America’s favorite cartridges over time for use on varmints or predators; coyote hunters love this round because it keeps pelts pristine and reduces meat damage among other benefits.

On paper, however, there are some notable differences between both cartridges that make them stand out from each other:

300 BLK .223 REM
Bullet Diameter .308 .224
Velocity Subsonic/Supersonic Supersonic Only
Muzzle Energy 1st Lvl – Subsonic/2nd Lvl – Supersonic (varies depending on load)

The most significant difference between both rounds lies with their bullet diameter size; while any expert will tell you that shot placement > caliber size when hunting or defending oneself against intruders — having bigger bullets can help with more significant tissue damage and expansion upon contact.

In terms of velocity and muzzle energy, the 300 Blackout seems to have the advantage. It can be shot at both subsonic and supersonic speeds, depending on your needs; whereas, .223 only offers you supersonic velocities.

Benefits Of Using The 300 Blackout AR-15

There are a few benefits to using the 300 Blackout AR-15 over other cartridges. Here are some of them:

Better Stopping Power

The 300 Blackout carries more energy upon impact than most other cartridges available in an AR platform; it is exceptional for use at short range distances (less than 200 yards) where stopping power can make all the difference.


The most significant advantage of using this cartridge is its versatility: by switching between subsonic and supersonic ammunition with ease — it makes for a perfect rifle round suitable for hunting game (similar to deer), defending one's property or home from intruders while keeping things quiet during late-night hours.

Compatibility With Existing Platforms

Since it was designed specifically for use in an AR-15 platform, there’s no need to go buying new guns or parts if you want to start shooting with this cartridge today. A simple barrel change is all that’s required before your existing firearm becomes capable of firing off these rounds like nobody's business!

Tips For Shooting The .300 BLK

If you’re planning on shooting a .300 BLK anytime soon – here are some tips that might help get started:

Get Yourself Some High-Quality Ammo

This cannot be overstated enough: always make sure you’re purchasing high-quality ammo whenever possible! This goes double if using subsonic loads as they tend not only lack speed but also kinetic energy when compared against their faster counterparts.

It's always best practice to get ammo from reputable manufacturers such as Hornady or Winchester who have been producing quality ammunition products since the 19th century.

Invest In A Quality Suppressor

Since subsonic ammo is a popular choice for this cartridge, it's essential to invest in a quality suppressor that can help dampen the sound of rounds being fired off; after all, you don’t want to be waking up your neighbors when shooting at night or alerting every game within a mile radius during hunting season.

There are plenty of great suppressors available on the market today designed specifically for use with 300 Blackout cartridges like those made by SilencerCo or Advanced Armament Corporation (AAC) if you're looking for something more high-end.


In conclusion, there’s no denying that the .300 Blackout AR-15 round has been gaining popularity among gun enthusiasts worldwide who are looking for something more versatile and powerful than their standard .223 Remington cartridge.

Whether using it as your primary rifle round or as an additional option in case things go south – this bullet is sure to get any job done! With its compatibility with existing platforms and ease-of-use — we’d recommend giving this one shot if given the opportunity to see how well it performs firsthand.


What is a 300 Blackout AR-15?

The 300 Blackout AR-15 is a rifle that uses the popular AR-15 platform and fires .300 AAC Blackout ammunition. This type of rifle was designed to offer users a versatile weapon that could be used for hunting, self-defense, and tactical operations. The 300 Blackout cartridge was developed specifically for use in suppressed firearms but has since gained popularity due to its versatility.

The beauty of the 300 blackout round is that it allows you to shoot both supersonic and subsonic rounds through your firearm by simply swapping out the ammo. Subsonic rounds are perfect for suppressor use because they are much quieter than their supersonic counterparts which makes them great when shooting at ranges with noise restrictions or if you don't want to disturb your neighbors while practicing on your property.

How does the performance of a 300 Blackout compare with other cartridges?

Compared to traditional cartridges like .223 Remington or NATO (5.56x45mm), the .30 caliber bullet used in this cartridge offers better knockdown power without sacrificing accuracy or range capabilities.

In terms of ballistics, when firing from an AR-style rifle, using basic ammo types such as FMJ (full metal jacket) or hollow points (HP), at typical shooting distances less than 500 yards/457 meters, there isn't much difference between .223/5.56x45mm NATO and .300 AAC compared side-by-side.

However, once you get into heavier bullets (>150 gr) from shorter barrels (<12 inches), this where things change significantly; The projectile will slow upon exiting shorter barrels but maintain high muzzle energy which makes it ideal if maneuverability were important factors on any operation.

Why should someone choose a 300 blackout over other cartridges?

If maneuverability matters more than long-range precision then one should consider using this platform versus others like say bolt action rifles. The platform is modular allowing for replacing the upper receiver and altering your weapon's caliber at will which makes it highly versatile.

Using a 300 Blackout in an AR-15 style rifle means that you have a wider range of ammunition types available to you. This includes both supersonic and subsonic rounds, which can be used for different purposes depending on your needs.

Another reason someone might choose this platform over other cartridges is its use in suppressors, due to the subsonic round option it’s able to provide reduced noise levels making them great tools for tactical operations or hunting without disturbing others around.

What are some features I should look for when purchasing a 300 Blackout AR-15?

When looking to purchase an AR-15 chambered in 300 blackout there are several things one should take into consideration:

  1. Barrel length: Ideally we recommend getting one with less than 16-inch barrels since going beyond this limit leads to serious issues regarding muzzle velocity drop.
  2. Rifle twist rate: selecting the correct twist rate will help maximize accuracy and achieve optimal stabilization of bullets within their intended weight range.
  3. Platform compatibility: Selecting an upper receiver that fits well with your lower receiver ensures proper function during operation.
  4. Sights or optics system: Adjustable iron sights coupled with red dot sight works best even though other options like magnified scopes work fine as well but might require more space due increased size.

Can I hunt using a .300 Blackout AR-15?

Yes, hunting using .300 blackout ar 15 setups is widely accepted by hunters who prefer shorter distance shots while maintaining high impact force on smaller game animals such as deer or coyotes.

The cartridge has been designed specifically from inception keeping hunters’ requirements in mind, providing them adequate stopping power at close ranges while still being relatively quiet compared with larger-caliber firearms especially when suppressed.

That said hunting regulation vary state by state, it’s important to do your research and check with local authorities on specifics such as caliber minimums or restrictions on hunting with suppressors.

When selecting the optimal bullet type for hunting; hollow points work great due to their ability expand more once making contact flesh even at lower speeds provided by subsonic rounds.
