Let's call them what they are:

42. Even bump-firing, an AR-15 can't touch the cyclic rate of an M16

because in an M16, the sear is tripped by the bolt carrier; the trigger doesn't have to be released and pulled again. While bump-firing, you float the rifle forward to allow the trigger to reset, but an M16 would have fired that next round as soon as the bolt closed. Bump firing is a fun simulation of cyclic, if all you are trying to hit is the berm, but put up 10 helium balloons a few feet apart and try to hit them bump-firing. Then try it from dynamic positions, and on the move, and with transitions from target to garget. I shoot competitively with an AR-15, and I guarantee that anyone who tried to clear an IPSC stage bump-firing would come in dead last.

An AR-15 doesn't fire any faster than a Ruger mini-14, or a 9mm pistol, or a 10/22, or any other civilian semiauto. I used to own a Mini-14 (Ranch Rifle) and functionally there is no difference between it and an AR, except that the AR makes a better target rifle.
