The .300 AAC Blackout (7.62x35mm) enhances the traditional 5.56 NATO by using many of the same parts but providing significantly more kinetic energy. Versatile in nature, it's effective as a supersonic option for medium-range shooting or as a subsonic, suppressed choice for close-quarters and hunting scenarios.
Our 300 Blackout uppers, perfect for your next AR15 hunting build, are designed to seamlessly integrate with standard 5.56 bolt carrier groups. This compatibility offers an effortless way to diversify your AR's capabilities without complex modifications.
