Easy to whine and say stuff like that. If you KNOW it put it out for everyone to see.
Put up or shut up.
Typical snobbery. Despite defending the purpose of the chart multiple times, it boils down to this against me: I'm all of a sudden against it because I see it as a tad out of date or possibly inaccurate for two models/mfgrs. Take yourself elsewhere.
A simply look on DPMS' and CMMG's site is proof enough, I'd say. CMMG has said directly and lists that their barrel steel is milspec. they list it as "milspec certified 4150 CMV". Pretty much the same thing as 11595E last time I checked; when the whole issue of "milspec barrel steel" first came up during the birth of the chart, there was a crapstorm over it, and a lot of the makers listed or were listed as using "4150 CMV" or something to that extent (LMT being the exception with "M249"). There's one good example.
Hating a spread sheet of info strikes me as very very odd unless you have a reason to not want the information disseminated.
Some people don't like hearing how their gun that they didn't pay top-dollar for, but still walked away with a terrific gun at a great price, isn't good enough to survive the rigors of combat. They see the all-blue columns by Colt, BCM, DD, LMT, and Noveske and think to themselves: "well, I still think my DPMS can hold up, blah blah blah...I still wouldn't hesitate to take it to a carbine class, etc." Basically your typical d***-measuring contest, and you came out the loser, but try to flip it and say its bigger when you measure it in metric.
The main thing the chart shows is minimum quality control. A Colt, etc. was made in a way to guarantee that it is as close to 100% quality as possible.
Does a batch-tested barrel or bolt mean less quality? Usually not. It just wasn't individually tested, but came from a batch where everything seemed fine to where the manufacturers trusted to put it into a rifle.
Now, proper staking of the gas key, shot-peening, the spring insert, and barrel steel DO make a huge, undeniable difference, depending on what the gun is meant for, as those pretty much set the bar for what the gun is going to be able to do.
