Can someone please enlighten me as to why a mil-spec buffer tube is considered to be so much better than a commercial tube? It seems to me that the only real difference is in the cost and method of manufacture, but I'm always open to having my paradigm shifted. I looked for this topic in the forums but haven't been able to find it. Also -- I have my Kuhnhausen books for my 1911 work, but what is the AR equivalent to those seminal tomes? Thanks in advance for reasoned, well-thought-out and well-intentioned replies...
