From the site:

Test results include:
  • 50,000 lube-free rounds on AR-15s.
  • 15,000 lube-free rounds on M9 pistols.
  • 18,000 lube-free rounds on carbine rifles.
  • 23,000 lube-free rounds on machine guns.

I remember once the military had a self cleaning weapon...

15k on a 9mm pistol isn't very many rounds. Neither is 18K on a carbine or 23K on a machine gun. 50K on an AR I would like to see though.
