Ok I have a A3 20 inch rifle with A2 stock i would like to make it a M4 lenght with A2 stock so should i keep my upper and just get a 16 inch M4 barrel ,gas tube and handgaurd or try and find another m4 upper and just have the ability to switch them out the 20 is a dart thrower very accurate any ideas are welcome.. thanks

Since the 20 is a good one, I'd go for another complete upper.  As far as I know, you can still have Daniel Defense build you one.  <thumbsup>
