What is the difference between an AR-10 and an AR-15?
The AR-10 is a larger-frame AR platform designed for full-size rifle cartridges, while the AR-15 uses a smaller receiver platform for intermediate cartridges. AR-10 platforms are commonly chambered in .308 Winchester/7.62 NATO, 6.5 Creedmoor, .243 Winchester, .260 Remington, and 8.6 Blackout, depending on the configuration. AR-10 rifles generally offer greater projectile weight and long-range capability, while AR-15 platforms are typically lighter and more compact. Parts compatibility varies, especially among different AR-10 patterns.
