I have one question for any AR-15 expert out there that may be able to help me. I have two pre-ban Colt AR-15's, how do I know if they have SAAMI spec chambers or NATO chambers? I have had them for many years and have fired all types of ammo through them with no problem. I was just curious after reading an article on Fulton Armory's website. Thanks in advance.

  They're NATO. All military rifles are throated for NATO-spec ammo. That is all non-Commie bloc military.

  Yea, from what I understand, all AR's are chambered to military throat demensions.
  
  If I'm wrong please correct me, I won't be offended.

  To be honest,have you ever heard ,read,seen posted anything about either one posing problems in the other.
  The only problem I have ever actually seen is that the 1/12 barrels will not stabilize the M856 tracers well.
  
  I will bet I have fired every load available to civilians in the USA.
