  1. There is no real difference in the operation of the two guns MAC channel shown, but only in the form of the bolt carrier. In the AR15 the bolt carrier is pushed rearward by the gas (direct impingement) and nothing else while, when this happens, the bolt is simply solidal with the receiver. In the MAS 49 what MAC called "the gas tube with a tiny little hole" is what in the AR15 was called "a piston" (a "stationary piston"). In the AR15 the "piston" (really the bolt) doesn't push the carrier at all, the gas does. The bolt it only seals the gas until the carrier retreated enough, exactly like the final portion of the gas tube in the MAS49.

  2.  @slthbob  Nothing goes on inside the bolt, sorry, and the AR15 isn't a gas delayed blowback system in any way (between the AR15 and a gas delayed system there is a further gradation, the "gas unlocked blowback action", like that used by the HS.404 and the Scotti MGs). In the AR15, when the gas pushes the bolt carrier rearward, the bolt is simply solidal to the barrel. The AR15 is a direct impingment action because the bolt carrier is directly pushed by the gas, and nothing else. There is NOTHING that mediates between the expansion of the gas and the bolt carrier. Obviously you can obtain it with different shapes of the bolt and the bolt carrier, like piston action can have different shapes of the bolt and the bolt carrier.

  3.  @slthbob  Sorry, but I explained my point. You, instead, preferred to talk about the sun.

  5.  @slthbob  And you still are incapable of talking about firearms. At this point you could have learned something.

  7.  @slthbob  So you are talking about medicine now? Think that, at this point, with a little studying, you could have been able to discern the stock from the muzzle.

  8.  @slthbob  And still you are incapable of talking about the matter. Unfortunately all that you are pointing out is your ignorance.

  9.  @slthbob  And still you are incapable of talking about firearms, and demonstrating that you are the one seeking for attention. You are pretty funny BTW. Keep on.
