Not a Jack of All Trades

The .300 Blackout cartridge fills more of a specialist role when compared to the 5.56x45m NATO cartridge. This means that you probably won’t want to make it the primary caliber of your AR-15 rifle. Where an AR-15 chambered in 5.56x45mm NATO is like a Swiss army knife in the many areas it can excel in, the .300 Blackout is more akin to something like a filet knife. It is very good at specific jobs, but not so great for many others.

Equipment Compatibility

If you already own an AR-15 chambered in 5.56x45mm NATO and are considering expanding into the .300 Blackout rifle world, you are in luck. The only thing you’ll really have to change out is the barrel. The .300 Blackout cartridge is compatible with every other part of a 5.56x45mm NATO AR-15 rifle. You may still want to build a dedicated .300 Blackout rifle to squeeze the most performance out of it, but if you are simply interested in trying out a new load, this is a viable option.

At the very least, you won’t have to buy all new magazines for a new .300 Blackout rifle as the cartridge works in 5.56mmx45 NATO magazines without sacrificing any capacity.

The Short Barrel Rifle (SBR) Way

For those of you who are interested in building an SBR, the .300 Blackout cartridge is an excellent choice. Considering the fact that it was designed for slower velocities, the .300 Blackout is superior in performance to the 5.56x45mm NATO when fired from a shorter barrel. The 5.56x45mm NATO typically has cycling issues in barrels of 10 inches and below and loses too much velocity to be an effective round downrange. 

The .300 Blackout doesn’t have those issues. In addition, it is also a relatively quiet cartridge when using subsonic ammunition and a suppressor. Suppressors are commonly used in SBR platforms so the .300 Blackout is really a match made in heaven for them.

What’s So Great About the 300 Blackout?

When the 300 Blackout burst upon the scene, it became widely popular with gun owners. More specifically, AR-15 owners and enthusiasts were quickly impressed with the Blackout due to its compatibility with existing AR-15 5.53/223 parts. This means the Blackout BCG, gas system, bolt, and pretty much everything that comes standard with an AR-15 is compatible with the 300 Blackout.

Another reason this weapon is considered one of the best is the ability to work with different kinds of ammunition without having to rely on adjustable gas. More specifically, we’re talking subsonic and full power ammo rounds. Best of all, you’re getting a great package deal that is light in weight, low in recoil, and tough as nails.

Pistol-Length or Rifle - Which is Ideal and Why?

One of the topics that is always the subject of debate is which gas system is ideal for the 300 Blackout. There are two types of gas systems: pistol-length and rifle. But which one is superior to the other?

While this question is often asked by those who are building a 300 Blackout rifle, this will also apply to those in search for a gun that will fire 300 Blackout rounds. Let’s take a look at each gas system:


According to some 300 Blackout owners, pistol-length is considered to be a popular choice. If you’re looking for a gas system that will give you the ability to shoot rounds that will hit targets effectively from about 200 yards out, this is the gas system to go with.

However, one of the major disadvantages of this gas system is the bullet drop. The bullet drop and velocities will likely be lower than the minimum levels of reliable performance.

Gas System Comparison (Photo credit:


This gas system will have the ability to work with super and subsonic loads. In other words, it won’t have an issue firing whatever 300 Blackout rounds you may have. Even better, you can do this either with or without the use of a gas can. This will also have the ability to handle high-pressure cartridges as well.

Of course, rifle-length gas systems do have their disadvantages. One of them is cycling issues. This is a common issue that 300 Blackout users deal with while firing subsonic ammo (this is more prevalent with factory version subsonics). These issues may come and go at times, but reloading may also be a little touchy at times.

So which is ideal and why? It’s quite obvious. If you’re looking to fire rounds from mid-ranges, you’re more apt to get a pistol-length gas system. However, if you want your rounds to travel farther, you’re going to need a rifle-length gas system for your rifle.

Aspects to Consider Before Buying a 300 Blackout Rifle

Before you choose a 300 Blackout rifle of your own, it is important to consider some of the factors that will drive your decision.

We recommend that you keep these in mind as you are looking around. Do not just buy the first one you see and call it good. You need to know more about what you are purchasing before dropping money on the table. 

Spending money on a rifle that turns out to be a disappointment will cost you a good amount of money and give you some headaches. Here are what some past 300 Blackout buyers have considered in their decision process:


Obviously, price is going to be a major factor for most buyers, especially for those who are either first-time buyers or budget shoppers. Either way, the price tag will always play a role in the decision process. One thing to make clear is that quality should always trump everything else. Just because it's cheap, doesn't mean it won’t be worth giving it a look. The rule of thumb is to find the highest quality product that you can find at a price that fits your budget.


Are you looking for a long-range rifle for hunting or competition purposes? Or are you simply looking for something that can hit targets from short or mid-ranges for hunting? Either way, finding a rifle with the ability to hit targets from certain distances will be important.

One thing to pay attention to is the gas system tit has. Pistol gas systems will be more suitable for 300 Blackout rifles that can fire rounds that travel 200 to 300 yards, while rifle-length gas systems will be powerful enough to send rounds a little farther.

Intent and Purpose

What do you plan on using your rifle for? Are you a hunter? Are you using it for home defense? It's important to know what your exact intent and purpose are for your 300 Blackout rifle.

If you're looking for a good home defense option, some of the pistol-length 300 Blackout guns might be more suitable for you.

Likewise, a longer barrel might be something worth looking at if you're using it for hunting or other outdoor activities like target practicing or competitive shooting.

Best Uses For a 300 Blackout

For each 300 Blackout user, they all have a specific purpose for their rifle. However, there are some good uses for a 300 Blackout.

One of them, of course, is hunting. A good 300 Blackout rifle can be reliable for hunting varmints or large game like deer or elk.

Another good use for a 300 Blackout is for competition purposes. A Blackout rifle is capable of holding its own against long-range rifles like those that have the ability to fire long-range rounds like 6.5 Creedmoor rounds.

Finally, you can also be able to use your 300 Blackout rifle as a reliable home defense gun. Some may say that the use of a rifle like this (or an AR style rifle) might be overkill. But it can still be just as effective as any other rifle you use.


The best 300 Blackout rifle is out there for you. It's a matter of finding one that will fit your personal preferences, your intent and purpose, and most importantly, your budget. Feel free to look around and don't be afraid to check out what people are saying about these rifles in general.

If there's one in particular that you like, it's important to gather more intel about it before making a final decision. If this is your first time buying a 300 Blackout rifle, we can promise that once you try this out, you won't be disappointed.
