AR-15 vs. AR-10: Choosing the Right Rifle for Your Needs
Mar 13th 2025
When it comes to modern sporting rifles, two of the most popular platforms are the AR-15 and the AR-10. Both rifles share a similar design and modularity but differ significantly in caliber, power, range, and applications. Whether you're looking for a lightweight tactical rifle or a hard-hitting battle rifle, understanding the key differences between the AR-15 and AR-10 will help you make the right choice.
In this blog, we’ll explore their history, specifications, pros and cons, and best use cases to help you determine which rifle suits your needs best.
A Brief History of the AR-15 and AR-10
The AR (ArmaLite Rifle) series was designed by Eugene Stoner in the 1950s. The AR-10 was the original design, chambered in 7.62×51mm NATO (.308 Winchester) and intended for military use. However, due to weight and recoil concerns, a scaled-down version—the AR-15, chambered in 5.56×45mm NATO (.223 Remington)—was later developed.
The AR-15 quickly became the U.S. military’s standard issue rifle (as the M16/M4) and is now the most popular civilian rifle in the United States. Meanwhile, the AR-10 remains a favorite for long-range shooting and big-game hunting due to its larger caliber.
