So I want a 9mm AR pistol to go with the 300BO one for cheap plinking. I'm probably going to go dedicated lower for Colt Mags w. the usual brace dealt etc but I'm a bit confused about uppers.

Are they still mag dependent? I was looking at the Bear Creek since I like my 300 upper from them and I can't fathom if it will work with a Colt mag or Glock mag or both?
Little help?
