AR-10

The AR-10 and AR-15 primarily differ in the caliber of ammunition they use: the AR-10 is chambered for larger rounds like .308 Winchester or 7.62x51mm NATO, while the AR-15 is designed for smaller calibers like .223 Remington or 5.56x45mm NATO. This leads to differences in size and weight, with the AR-10 being heavier and better suited for long-range precision and larger game hunting, and the AR-15 being lighter, offering quicker handling and reduced recoil for smaller game or tactical use. Both share a modular design but have non-interchangeable parts due to their size differences.
