In this day of a bewildering array of A.R. manufacturers, how can it be that no one makes an A-1 style upper, let alone complete rifle. I would be the first on line for an origional style barrel in the 1:12 twist and triangular hand guards, with tho old style upper. My preference would be to an A-1 upper, but even an old style smooth side would be nice. It seems to me that even if I am requesting a niche market item, there would be enough business to make a profit. After all, look at all those makers chasing EXACTLY the same market with EXACTLY the same rifles.
