Excellent write up, IG, and much appreciated. I'm printing this and putting it in with my tools and spare parts.
I also stickied the thread. Do you want this to stay in AR General Discussion, or want me to move it to Ar Technical Discussion? Seems like a good fit in either location.
Excellent info again, IG.
FYI, my Colt 6520 purchased new in 2010 came with an H2 buffer like their M4/M4A1 carbines, rather than the H buffer like their 6920. Has Colt switched back to the H?

Great post!
If I may add to this section about tuning, and ammo selection.
Don't forget to consider cold weather, lubrication and fouling when tuning the rifle to your ammo.
If you tune your rifle to your least powerful loading and the rifle JUST functions when using it, you will begin to have failures when your rifle gets dirty, looses its lubrication or is used in colder weather.
You have to allow for function during these conditions or you will be dealing with a rifle that works great clean and slick but as the day progresses, you will encounter problems.

"There are 550 million firearms on this planet. That's one firearm for every 12 people. The question is... How do we arm the other 11?" Lord of War.
"I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them." Thomas Jefferson
In my short experience I try and slow down the cycling rate as much as I can with buffer weight and maintain function. I am not sure if this is the right thought process or not, but it seems to work. I run an H2 in a midlength with shit Russian ammo reliably. I could not detect bolt bounce when running 5.56 (mil pressure) ammo. I assume with higher pressure ammo the gun will run faster, but if I set it up for 5.56 it may not run shit .223 well. I try to set it up for the least common denominator.
Off topic warning - I ran into 3 McLaren mechanics during the 2006 US Grand Prix in Indy... in a gun store that rented firearms/range in the back lol. Poor Brits without guns... The conversation did not go well as I am a crazed Ferrari Fan
Back to your regularly scheduled program.
