I bought a Vortex Razor so I am looking for bases now. I see 2 companies that make qd 35mm systems. American Defense or Larue. Both cost about the same, the American Defense Recon is right around $169 and then LaRue is $195. For those that have used both, is the LaRue any better or is it about the same in terms of quality and reliabilty. The American Defense looks heavier.
