AR-10 vs AR-15: Which is the Best Rifle for You?

Featured in:

AR-10 and AR-15 rifles are two of the most popular firearms in the United States, and their popularity has only increased with time. Many people often get confused between these two rifles, as they share many similarities but also have some fundamental differences. Thus, today we will be discussing AR-10 vs AR 15.

Firstly, it's essential to understand that both rifles were designed by Armalite in the late 1950s and early 1960s for military purposes. However, over time, these weapons have become increasingly popular among civilians for recreational shooting or self-defense purposes.

While both guns are semi-automatic and fire the same ammunition (5.56 NATO or .223 Remington), there are some significant differences in their design that sets them apart from each other. These differences include weight capacity, accuracy range capabilities recoil management system amongst others which we will discuss further on this article.

If you're interested to know more about how AR-10 compares to its cousin weapon -the famous AR-15 rifle-, then keep reading because our comprehensive guide is here to help you distinguish between these two formidable firearms without leaving any stone unturned!

AR-10 vs AR-15

When it comes to choosing between the two most popular rifles in the world, the AR-10 and AR-15, many people are left confused. The similarities between these two weapons run deep – they look almost identical, they both use 5.56mm ammunition and share a number of interchangeable parts. But what sets them apart? In this article, we will take an in-depth look at the differences between these two guns to help you make an informed decision.

What is an AR?

First things first: let's talk about exactly what we mean when we say "AR". Contrary to popular belief, this term does not actually stand for "assault rifle". Rather, it refers to a platform that was originally developed by Armalite (hence "AR"). This platform has become incredibly popular over time due largely to its customizability – users can swap out different components as needed for different purposes.


Before delving into more specific differences between the two weapons systems here's a brief overview of their respective histories:

The AR-10 was designed by Eugene Stoner while he worked at Armalite after being inspired by his work on aircrafts within Hughes Helicopters during mid 1950s . It was initially intended as a battle rifle with select-fire capability chambered in 7.62×51mm NATO round.

The ArmaLite Rifle model 15 (AR–15) is a lightweight semi-automatic assault rifle based on Stoner’s designs from years before.. It fires intermediate cartridge rounds such as .223/5.56x45mm or even .300 Blackout etc., and has been adopted worldwide by militaries and law enforcement agencies alike due primarily to its modularity.

Caliber Differences

Both rifles were created with distinct calibers: The original ArmaLite Model had originally been designed around NATO standard 7.62x51mm cartridge and the AR-15 was designed around a smaller .223 Remington / 5.56mm NATO cartridge.

The larger caliber of the AR-10 offers more power at shorter ranges than its counterpart, making it an ideal weapon for hunting and tactical use where stopping power is key. The downside however, is that larger rounds usually bring with them greater recoil which can make follow-up shots slower.

On the other hand, the smaller caliber of the AR-15 results in less recoil compared to AR-10's heavier round making it easier to handle for beginners or those interested in shooting for longer durations at range without fatigue.

Magazine Capacity

Another difference between these two rifles comes down to their respective magazine capacities: Due again mainly due differences in their calibers – generally speaking a .308/7.62 mm round takes up much more space than an intermediate round like a 5.56mm or .223 – means that magazines used by both systems are not interchangeable.

In most cases, you can expect an average thirty-round magazine capacity with an AR-15 while its bigger brother will have closer to twenty rounds per mag depending on how they're loaded (single column vs double column).


Weight difference between these two rifles is significant enough that when handling either one you'll notice pretty quickly — while they may look similar from afar once you get up close & personal differences become apparent! An unloaded typical weight of an ArmaLite model ten rifle ranges anywhere from eight-and-a-half pounds all way upto twelve pounds whereas your standard issue ArmaLite Rifle model fifteen weighs around six-and-a-half pounds out-of-the-box – meaning it’s noticeably lighter right off bat lifting them side-by-side.


At this point we've covered some of key differences between these popular weapons platforms including but not limited too calibers; capacities; weights etc… so hopefully now you have a better understanding about differences between AR-15 vs. AR-10. Ultimately, the choice between which of these firearms is right for you will come down to your personal preferences and needs – so take time to research before making any purchase decisions!


What is the difference between an AR-10 and an AR-15?

The AR-10 and the AR-15 are two very similar, yet distinct rifles. The primary differences between them lie in their size, power, and intended use.

Firstly, the most obvious difference lies in their calibers. The standard caliber for an AR-15 is .223 Remington or 5.56 NATO rounds while the standard caliber for an AR-10 is .308 Winchester or 7.62x51mm rounds.

Secondly, despite sharing a lot of design elements with each other both rifles have different dimensions which make them unique from one another – with the bigger dimensions belonging to ar 10: It has a longer receiver than its counterpart (the ar 15), this makes it more comfortable to grip and hold on to as well as supports larger magazines that can hold more bullets at once.

Finally, these differences result in different advantages depending on your usage: While they're both suitable for hunting purposes (with some limitations), due to higher power ratings of ar10s they tend to be better suited for long-range shooting while Ar15s are great when it comes down close-quarters situations like home defense or tactical operations

Which rifle would be best suited for sport shooting – Ar 10 vs Ar 15?

When it comes down purely choosing either one based off sports performance then there's no clear winner since both guns do excel in their own unique ways

For instance; if you’re looking into participating big game hunting competitions at longer distances then most experts suggest going towards owning an ar10 due its ability pack much heavier firepower hence being better-suited against larger animals such as elk,bear etc.. Alternatively if you're interested more so into certain types of shooting competitions such as IPSC matches where rapid-fire accuracy takes priority over sheer power output then perhaps owning something like our beloved semi-auto fire arm "Ar 15" can give you an edge over others due to its lighter weight and easier maneuverability.

What are the regulations regarding owning Ar-10s/Ar-15s in the United States?

In terms of regulations, the AR-10 and AR-15 are both considered semiautomatic rifles, which makes them legal to own in most states within the US. However, this is subject to change depending on your location or possible new amendments made by your state's government.

It's important that you familiarize yourself with local firearms laws before purchasing any firearm for instance if you live within California then there're specific regulations surrounding magazine capacity limits (being capped at 10 rounds) hence affecting which type of gun would serve as a better pick etc..

In general though as long as one is not a felon nor designated mentally ill individual they should be eligible under current federal law provisions.

Can an Ar 15 upper receiver work with ar 10 lower receiver?

No , The receivers from these two weapons systems are completely different – therefore it is impossible to use an AR-15 upper receiver on an AR-10 lower or vice versa since their sizes and shapes do not match up whatsoever – even trying so will potentially lead dangerous misfires that could severely endanger people around

While some may try interchanging parts between these two weapon systems just because they look similar at first glance but doing so would only lead towards serious mechanical failures requiring expensive repairs/replacements altogether!

What kind of ammunition does each rifle shoot?

The standard caliber for an Ar 15 rifle model fires .223 Remington or its military equivalent: NATO round – while those interested more so into varmint hunting etc. might opt going higher grain variants such as .243 winchester etc..

On other hand pro-gun enthusiasts who prefer having access much heavier firepower such as taking down large game animals like moose/deer/bear/etc., commonly turn towards owning an Ar 10 rifle model which chambers .308 Winchester cartridges or its military equivalent: 7.62×51mm NATO round.

It's important to note that both of these rifles can be modified to accept different sized calibers if you have the required parts and license to do so – but such changes aren't generally recommended for beginners since they could affect accuracy/handling all together!
