I was reading the Colt M4 article in the most recent American Rifleman, and it said the barrel nut torque specs for the M4 had been changed from the spec for the M16.
What's that all about?
Thanks in advance.

I use 35-80ft lbs.
Because not all barrels and barrels nuts will thread on and line up exactly the same way everytime. Remember that the barrel nut has to line up right to insert the gas tube. I have personally never used a torque wrench when installing a barrel and I have never had one come loose either.
So the article was wrong, and the specs for both the M16 and M4 have never changed?
I just looked at the article you spoke of and read that tidbit about the barrel nut. I then checked my M16A1 manual and it also shows 30-80 ft-lbs.
My guess is that it was a change that was instituted before being released which means that someone at Colt has that answer.
