Looks like the A1 lasted longer.

That was cool. A little curious why the A1 lasted twice as long almost
All that is necessary for the triumph of evil is that good men do nothing.
Heavy barrel according to something I read yesterday. Pentagon is considering purchasing upgrades pretty quickly.
AFAIK this has come to a head since some soldier complained about his M4 failing during a firefight a few months ago.
BTW I thought all our AR/M type rifles were semi/burst only, no more full autos.

The Making of the Military’s Standard Arms, Part II
By C.J. CHIVERS
...Colt Defense and the Army have been discussing making the change to a heavier barrel for several months and appear likely to begin requiring standard-issue rifles to have the barrel previously manufactured for the M-4A1.
If the change is made, the standard M-4 will retain its semiautomatic and burst modes of fire. It will not fire automatically.
Because both the lighter and heavier barrels are machined from identical sleeves of steel (the thicker barrel, in the simplest sense, spends less time on the lathe), the change can be made without increasing the cost per rifle.
...“The bottom line is that we are going to do this,” Colonel Douglas Tamilio, who supervises small arms development for the Army, said of the change to new carbines. “We have to get all of the services to buy in, but it adds five ounces in weight and doubles your sustained rate of fire.”
He added, “I think it’s a no-brainer, and we’re going to see it in the near future.”

I like the videos. They're confidence inspiring when you consider that machine guns aren't even fired like that.
Lesson: your rifle is not a machine gun.
