AR-10 vs AR-15: A Comprehensive Comparison

When it comes to the world of modern firearms, the AR-10 and AR-15 are two of the most popular and widely recognized rifles. Both are based on the original ArmaLite rifle designs, but they have evolved into distinct platforms with their own unique features and advantages. In this detailed comparison, we’ll explore the various aspects of these two rifles to help you understand their differences and decide which one might be the better choice for your needs.

Design and Origin

The AR-10 was designed by Eugene Stoner in the early 1950s, while the AR-15 was developed by Stoner’s team at ArmaLite in the late 1950s. The AR-10 was initially intended for military use, but it was not adopted by the U.S. military. However, it has since gained popularity among civilian shooters and hunters. The AR-15, on the other hand, was designed for civilian use and quickly became a favorite among recreational shooters and law enforcement agencies.

Caliber and Performance

The AR-10 is chambered in 7.62x51mm NATO, while the AR-15 is available in a variety of calibers, including 5.56x45mm NATO, .223 Remington, and .300 Blackout. The 7.62x51mm NATO round offers greater stopping power and range compared to the 5.56x45mm NATO and .223 Remington rounds. However, the heavier bullet and increased recoil of the 7.62x51mm NATO round can make the AR-10 more challenging to control in rapid fire situations. The lighter bullet and lower recoil of the 5.56x45mm NATO and .223 Remington rounds make the AR-15 more suitable for rapid fire and close-range combat.

Weight and Size

The AR-10 is generally heavier and longer than the AR-15. The AR-10 weighs between 7.5 and 8.5 pounds, depending on the model, while the AR-15 weighs between 6 and 7 pounds. The AR-10 is also longer, with a barrel length of 20 inches or more, compared to the AR-15’s barrel length of 16 inches or less. The heavier weight and longer length of the AR-10 can make it less maneuverable in tight spaces, while the lighter weight and shorter length of the AR-15 make it more versatile for various applications.

Accessories and Customization

Both the AR-10 and AR-15 are highly customizable platforms, offering a wide range of accessories and upgrades. The AR-10 has a larger receiver, which allows for more extensive customization options, including heavier barrels, longer handguards, and larger magazines. The AR-15, while still offering a wide range of customization options, may be limited by its smaller receiver size. However, the AR-15’s popularity has led to a vast selection of accessories and parts, making it easier to find compatible options.

Cost and Availability

The AR-10 is generally more expensive than the AR-15 due to its larger size, heavier materials, and limited production. The cost of an AR-10 can range from $1,000 to $2,000 or more, depending on the model and features. The AR-15, on the other hand, is more affordable, with prices ranging from $500 to $1,500 or less. The lower cost and higher availability of the AR-15 make it a more accessible option for many shooters.
