7.62 typically refers to rifle cartridges like 7.62×39 (used in AK-47s) or 7.62×51 NATO/.308 Winchester (used in AR-10s and other battle rifles). While not a manufacturer, many firearms companies produce 7.62-specific parts, including barrels, upper and lower receivers, bolt carrier groups, magazines, and complete rifles. These components are compatible with platforms such as AK-47s, AR-10s, and other 762 rifles, making 762 a popular choice for shooters and builders seeking reliable, hard-hitting performance for hunting, sport shooting, and tactical applications.
