When it comes to selecting the best AR pistol that meets your shooting needs, you want a weapon that not only delivers unrivaled performance but also a remarkable shooting experience.
The world of AR pistols is vast and varies, giving you lots of choices and leaving you overwhelmed.
With that in mind, we compiled a list that will help you choose the best AR pistol for yourself.
Understanding AR Pistols
But, before diving deep into reviewing the best pistols, let’s see what’s the difference between an AR pistol and an AR-15 rifle.
As per the name, you can assume these two are very similar. Both of them have the AR15 pattern as you can expect.
However, AR pistols don’t have a stock compared to AR15 which is a rifle.
Also, AR pistols weigh less and have shorter barrels making them a little easier to handle compared to standard AR15 rifles.
There is still a possibility to add a pistol brace to the AR pistol to make up for the lack of stock. However, we would advise you to pay attention to your country's laws and limitations.
To understand the AR pistols even further, let’s break down key parts of this firearm.
At the core, there is a lower receiver, housing the trigger mechanism and controls.
Then, there is an upper receiver attached to the lower receiver and it has a barrel, bolt carrier group, and handguard.
As you can notice, the pattern is the same for both AR pistols and AR15 rifles.
Despite some differences between these two firearms, both of them have benefits in different situations.
For example, compared to an AR15 rifle, an AR pistol is better in close-quarters shooting and home defense situations.
Benefits of AR Pistols
If you’re in doubt about whether to own an AR pistol or an AR rifle, you should know that everything depends on your personal preferences.
Here are some benefits of an AR pistol:
- Compact size - AR pistols are typically shorter than AR rifles. A great option if you’re planning on using it in close-quarters scenarios.
- Versatility - AR pistols can be also equipped with various accessories like AR rifles. You can customize an AR pistol in various ways to make it match your individual needs.
- Legality - In some jurisdictions, AR pistols may have certain advantages over AR rifles.
- Reduced recoil - Design and shorter barrels often have less recoil than rifles.
- Personal Defense - Their smaller design makes them a better option for home defense.
These are some of the benefits of an AR pistol over an AR rifle, however, you should go with the option that suits your needs the most as an AR rifle may be a better option for some scenarios.
Choosing the Right AR Pistol
As there are plenty of different options available on the market, choosing the right AR pistol may be a time-consuming and overly overwhelming process.
In order to choose the right AR pistol, the best approach is to define what’s the purpose of buying a gun, how much money are you willing to spend, and many more factors.
Now we’re going to explore those factors you can put on paper and define what’s the best option for you.
The right choice of caliber can directly affect the performance of your rifle. One caliber may be better for long-range shooting, but others may not.
As for the AR pistol caliber, it includes the widely popular AR pistol 5.56 (.223 Remington/5.56 NATO).
Others you may consider are .300 Blackout and .308 Winchester calibers.
The 5.56 caliber AR pistol is known for its accuracy and wide availability compared to other types of ammo. This is a great choice for home defense and target shooting.
On the other hand, we have .300 Blackout caliber which excels in short-barrel setups. It’s great if you’re looking for a quiet and hard-hitting round.
If however, you’re going to use your AR pistol for hunting, the best choice would be a .308 Winchester with even more power than .300 Blackout ammo. It’s a great choice for long-range shooting too.
All in all, determining the best caliber for an AR pistol highly depends on where and how you’re going to use it.
Barrel length and twist rate
These two parameters have a high impact on rifles' performance and when it comes to barrel length and twist rate, there are a lot of different builds made for specific situations.
Most of the time, the barrel length for an AR pistol goes from 7.5 to 12.5 inches while the most common twist rates are 1:7 or 1:8.
If you’re looking for something maneuverable you may find shorter barrels as a better option. However, for long-range targets and hunting, a longer barrel will deliver better results.
As for the twist rate, it’s important to match the proper ammo with the twist rate to get the most out of it.
Gas system type
There are two primary types of gas systems: direct impingement (DI) (traditional one) and specially made pistol-length gas systems made for AR pistols.
The DI system is a popular choice among AR rifles too, not only for AR pistols. It uses a portion of gases to cycle the firearm.
On the other hand, pistol-length gas systems are specially made for AR pistols. Because of that, they have better recoil, muzzle rise, and reliability.
Size and weight
Handling of the weapon largely depends on its weight and size.
AR pistols are made to be lightweight and easy to handle compared to AR15 (or AR10) rifles.
When talking about the weight of an AR pistol, you should pay attention to additional accessories you add like optics, handguards, foregrips, or any other types of accessories.
Ergonomics and accessories
To get a better shooting experience it’s important that a weapon (in this case AR pistol) is made to provide a comfortable feeling.
If you pick a well-designed AR pistol, you will get a comfortable grip, intuitive controls, and a natural point of aim.
Besides that, consider the availability of accessories for the AR pistol platform. Angled foregrips, handguards, optics - all can improve the functionality of your firearm.
How much money are you willing to spend is also a factor to consider when purchasing an AR pistol.
For example, you can look for Sig Sauer AR pistols, but in that case, you must be willing to break the bank.
While it can be tempting to go for high-end AR pistols with all the features coming with them, it’s still important to consider the best AR pistol for the money.
If however going for high-end AR pistols is not your case, then you should evaluate all options and look for those providing a good balance between price and performance.
