Hello. New here, so I'll try to explain what am looking for. I want to put a tripod on my mini 14. I have a few friends telling me I can't cause I have a #582 serial number (which I don't understand why that matters). And then others say I need an adapter t mount a tripod. So, if there's anyone out there that has put a tripod on their mini, can you tell me what I need to do? Thank You...
