Since you never took the time to read the thread referred, but instead preferred to dig up posts here before I was aware of the issues, here are the correct functional parts for the recoil system to work without beating itself to pieces along with your shoulder......

First off, those are not "the" correct parts, thats "a" correct set of parts. You could also say that a standard carbine length buffer tube, the appropriate spring, and a 2.5" buffer are also "a" correct set of parts. A properly timed PSA rifle length AR10 buffer tube, the appropriate spring, and 3.25" carbine buffer are also "a" correct set of parts. There are a lot of possible combinations that function perfectly fine, without even getting into spacers...and if you are telling me that only those three parts work, well... you really do need to do more research on this particular topic. Blaming your lack of understanding on PSA is just silly. Put together an Aero build with a rifle length buffer tube and a 2.5" AR10 buffer without a spacer and tell me how that goes for you.
As far as the article, I did read it. I read that thread over a month ago when I was researching my purchase.
Before I bought my upper, which is why I have $0.50 sitting in my buffer tube and no carrier marks on my receiver. As far as that goes, good stuff. The rest? Not so much.
Basically; Add a quarter or two to the buffer tube if you need to but gosh that's really hard, and If you add 1.5oz. to your buffer all your overgassing issues will be solved but if you don't add 1.5 oz to your buffer, the next time you fire your rifle it will fall to pieces in your hands and kill a puppy. Adjustable gas block? Never heard of it.
Nothing really worth clutching your pearls over, and certainly not a particularly damning indictment there. No broken rifles, no receivers battered to oblivion, no catastrophic malfunctions. Replacing your H buffer with an H3 buffer is not the game changer that person is making it out to be. Not one mention about using an adjustable gas block, with is hinky, to say the least. That person just wanted to rant, imo, and that;s a classic example of someone blowing a molehill into Mt. Everest.
I even question whether that person knows what they are talking about. There are a lot of people who have gone with heavier buffer and spring combos that have reported not being satisfied with the results until they also added an adjustable gas block. The problem is not that the buffer is 1.5 oz. too light, ultimately its with the barrel port size, and the most effective way to mitigate excessive gas is with an adjustable gas block, not a heavier buffer. Frankly, the only reason I didn't just get an adjustable gas block from the beginning is I don't particularly want to take my flash hider off if I can get around the problem with a buffer/spring swap. My opinion of that thread is the author is just plain wrong and just wants to rant about buffers and PSA. If he actually knew what he was talking about he'd be telling PSA to include an adjustable gas block on all their PA10's, not ranting about buffer weights.
Regardless, The vast majority of the PA10's reportedly run just fine with an H buffer and the PSA supplied spring.
I don't know about you, but if my rifle was functioning as well as yours, I wouldn't be chasing ghosts on the internet trying to invent problems that your rifle doesn't have. The bottom line is, you don't have a gas tube issue. I know this because you have said your rifle functions perfectly as it sits. A short gas tube will make your rifle short stroke. Your rifle does not short stroke. It runs perfectly, according to you. If you don't like the recoil, get a muzzle brake like everyone else. Its what they are for, and I'll bet even money that the other two AR 308's you are comparing with had either muzzle brakes or AGB's which is why you say they were softer shooting that your PA10 with a flash hider.
As far as the buffer situation, since
you picked all the components of the buffer system
yourself, any problems with your buffer system arising from an improper configuration is
your fault. My PSA-assembled lower is fine. The overwhelming majority of other peoples PSA-assembled rifles are fine. I'm not going to spend $75 on a cosmetic issue that can be fixed in 20 seconds with $0.50.
order all 4 of those, and circular file what PSA put in it, and it will run like it should, instead of hammering away at itself. No freaking quarters either.
Why? Its a self limiting issue, and I don't need to spend $75 on an issue i've already solved. If I cared that much, I'd take the buffer tube off the gun and reshape the edge so it can be screwed into the receiver a few more rotations. I don't need to, because I fixed that issue in all of 20 seconds, and its cosmetic anyways.
Also note, over the past year, PSA has released no less than 17 different SKU's for .308 winchester complete uppers, some carbine length gas, midlength gas, and rifle length gas systems. So gas tube length is going to be a crapshoot based on what model you received.
Erm, no its not. If you order a barrel with a carbine length gas system, you get a carbine length gas tube with it. If you order a barrel with a mid length gas system, you get a mid length gas tube. If you order a barrel with a rifle length gas system, you get a rifle length gas tube. Its not rocket science.
This is literally what you have to do with every other AR platform using a DI system. PSA does not just throw a random length gas tube on a random length system. They test fire their uppers, for crying out loud. You think someone wouldn't notice a carbine length gas tube on a rifle length system blowing hot, 50,000psi gas all over their face? You are taking your desire to badmouth PSA to the point of ridiculousness here.
When you look straight down into the upside down upper, the gas tube should protrude about to the center of the half moon recess in the housing. if it just barely gets into the front edge of that area, it's not long enough to properly engage the gas key for the correct length of travel before it disengages.
Sheesh. One more time. If your rifle is functioning perfectly, as you say yours is, your gas tube is not too short.
For crying out loud you are telling us that you have deduced from your rifles perfect reliability and a picture you saw on the internet posted by some bozo that couldn't read instructions...that your rifle is simultaneously overgassed and undergassed, but it also runs perfectly. Thats emoticon worthy.
You are getting all worked up over a picture you found on ar308.com, and you are forgetting that
your rifle functions perfectly fine. in fact, you have yet to provide a SINGLE incident in which PSA installed the wrong length gas tube on a rifle, leading to function issues.
I'm pretty convinced at this point that you are just regurgitating stuff you found on the internet without really understanding what you are talking about.
I don't claim to be an expert, but I know that you need to get the right parts if you are going to build the gun yourself, you should research any AR 308 rifle extensively before you purchase or build it, and if your gun functions perfectly, it isn't broken.
Its stuff like this that leads me to believe that the PA10 has been pretty well sorted, its just at a price point that has let a lot of people jump into builds who don't really know what they are doing and don't bother to do the research needed, which has led to a lot of people jumping on a bandwagon and unfairly spreading nonsense about PSA. This, mixed in with some legitimate past issues and a few minor ongoing ones, has severely muddied the waters.
