Hypothetical AR question.

I was looking over the schematic and functioning of a civilian model AR-15 yesterday. It appears to me that if a person were to assemble the lower receiver, leaving out the primary sear it would operate as a full auto weapon. Am I correct in this? NO i would never do this. I dont even own an AR.

  Nope, the hammer just rides along behind the bolt carrier,there must be dis-connect and delay. A Marine?

  Maggie, I posted a reply to your same question over on general discussion. Jody is right and he was able to say in one sentence what took me three paragraphs to cover!

  Well, now just a minute! There is always the exception. There used to be a rumor, which some say is true, that if you load the cartridges with pistol primers, which are much softer, even though the hammer rides the bolt closed, it will still hit the primer hard enough to fire the cartridge, thus achieving full-auto fire.
  
  Of course, if the hammer has the notch and the bolt carrier has the lip on which to catch the hammer as used in Colt AR-15 rifles after the first year or so, the hammer and bolt carrier will jam together and nothing will happen except a malfunction.
  
  Back in the days when surplus M16 parts were used in semi-auto rifles by the clone makers because they were less expensive, I am told that if a clone rifle had the M16 hammer and bolt carrier, and the disconnector were removed, that the use of the pistol primers in the ammunition would achieve full-auto fire. The rumor was further embelished to say that ATF agents looking to bust someone with M16 parts in their AR-15 (clone or Colt) would remove the disconnector and use ammunition loaded with soft pistol primers to achieve full auto fire, thereby creating an offense with which to charge the owner or possessor.
  
  Is any of this true? I think it might be, but who knows? I will have to go to the other discussion to see if I have missed anything.
