The only one I have shot is a RRA, functioned well, but to be honest, I put 20 rounds through it, no long term impressions.
I have heard good things about the DPMS. I think they have more on the street than either the RRA or Armalite, but could not prove that, just internet chatter.
Don't several of them use propietary mags?
