What should I look for when buying an AR-15 lower receiver?
When choosing an AR-15 lower receiver, consider whether you want a stripped or complete lower, forged or billet construction, manufacturer, finish, and included components. A stripped lower provides the receiver itself for further configuration, while a complete lower generally includes installed lower components and may include a buffer system and furniture. Always confirm compatibility with the intended upper and follow applicable transfer and configuration requirements.
