You can buy one high quality AR10
That is only true based off what you consider "high quality", below are what I would call high quality.
KAC SR25 will run you $3,200-$22,500 depending which one you get
Basic DD AR10 will run you $2,800
JP Enterprises LRP will run $3,600+
The DPMS, Armalite, Aero M5, PA10's, M&P10, etc... are not "high quality" in my book. Some are great budget AR10's, but certainly not "high quality".
