When it comes to firearms, the AR-15 and AR-10 are often mentioned in discussions. But what exactly sets these two rifles apart? Let's delve into the differences between the AR-15 and AR-10 to gain a better understanding of these popular firearms.
Caliber
One of the primary distinctions between the AR-15 and AR-10 rifles is the caliber they are designed to fire. The AR-15 typically fires the .223 Remington or 5.56x45mm NATO cartridge, which is known for its lower recoil and versatility. On the other hand, the AR-10 is chambered for the larger .308 Winchester or 7.62x51mm NATO cartridge, offering more power and range compared to the AR-15.
Magazine Compatibility
Another difference between the AR-15 and AR-10 lies in magazine compatibility. While both rifles may appear similar in design, the AR-15 and AR-10 magazines are not interchangeable due to the variations in caliber size. This means that the magazines designed for an AR-15 will not fit or function properly in an AR-10, and vice versa.
Recoil and Ballistics
Due to the difference in caliber size, the AR-10 typically has higher recoil compared to the AR-15. The larger and more powerful .308 Winchester round generates more recoil when fired, which can impact accuracy and shooter comfort. Additionally, the AR-10's larger caliber results in improved ballistics and long-range performance compared to the AR-15.
Size and Weight
In terms of size and weight, the AR-10 is generally larger and heavier than the AR-15. The AR-10 was originally designed as a battle rifle, featuring a longer receiver and stock to accommodate the larger caliber rounds it fires. This results in a heavier overall weight compared to the lighter and more compact AR-15.
Customization Options
Both the AR-15 and AR-10 offer a wide range of customization options, allowing shooters to tailor their rifles to their preferences. From different stocks and grips to various optics and accessories, the possibilities are endless when it comes to making your firearm unique to you.

Which One is Better for Hunting or Target Shooting?
Ultimately, the choice between an AR-15 and AR-10 depends on your intended use and preferences. If you prioritize a lightweight and versatile rifle for recreational shooting or home defense, the AR-15 may be the better option. However, if you require a more powerful and long-range rifle for hunting or tactical applications, the AR-10's larger caliber and capabilities may be more suitable.
