What parts are needed for a complete AR-15 lower?
A complete AR-15 lower generally includes the lower receiver, lower parts kit, trigger or fire-control components, pistol grip, buffer tube, buffer, buffer spring, and stock or other appropriate rear configuration. The lower also works with a compatible AR-15 magazine. Exact components vary by configuration, and some lower parts kits exclude the trigger, grip, or buffer system, so always check what is included before purchasing.
