Uh...go back up and read post #29. The majority of the post describes known issues with the rifles in general, the issues I've had with mine, and how I've addressed them.
Ok, this is just nonsense. In all probability, given the positive reports I've read even on this thread, compared to the negative reports, this is simply not true, and not even logical to assume. All reports indicate the majority of guns DO come out of the box as a good running gun. By all reports they function, fire, eject and load without issue. Now, you've had some issues, but this is just a ridiculous statement.
How do you know the gas tube is short and the buffer is still on the light side?
Good...like, better than
?
Again...What issues? How is your gun malfunctioning?
Aaaand....still waiting for you to make me aware of the problem you are having with your rifle.
I really don't get your gripes with your rifle, and your baseless opinion of PSA10's The majority of them work fine out of the box. Any point after you got your build straightened out, did yours not? PSA took care of you, then your rifle shot awesome according to you. Fill us in.

Did you read the thread on 308ar forum? Seriously, they lay it all out better than I ever could. I am not the expert, but since my initial experience with my rifle, I have since shot my ammunition from a POF rifle, and a DMPS gen II rifle, and the recoil on mine is significantly higher, due to the buffer weight being too light, and the gas tube is short, as detailed as well on the 308ar forum by numerous other posters. Mine is not as bad as many others have experienced, but it is running a bit on the fast side, due to the light buffer.
https://forum.308ar.com/topic/16471-the-problems-with-the-pa-10-carbine-recoil-system/
There it is laid out plain as day.

Did you or did you not ever have function issues with your build?
Is this the bottom line? There are no function issues with your rifle, but that read a few threads on the internet about bolt speed and buffer weight (universal to the AR 308 platform, by the way), so PA10's suck?
I have a PA10, I added an H3 buffer and flatwire spring, and might add an adjustable gasblock...but thats my preference. I would prefer the gas port be drilled smaller. I'd prefer that PSA ships their adjustable gas block on all their large frame AR rifles and uppers. I prefer it that way to save my brass from being bent to heck and flung into the next county. I prefer it that way to make it a more comfortable rifle to shoot
However, just because that is my preference and PA10's are not sold according to my preference, PA10's do not automatically suck or have issues beyond any other AR 308 build

well, to start off, the buffer tube and buffer and spring were all wrong from my initial order, and I ordered from their website the proprietary parts specific to their PA10, but individually, since they had no bundles. After reading the threads on 308ar forum, BEFORE ever firing the rifle I found the BCG would crash into the lower receiver as is. This required a new buffer tube, spring and buffer. That was the most serious initial problem. Had I not read the threads, and fired the gun it would have dents all over the ears at the back of the lower where the buffer tube screws in. Now, the gun is running, and very accurate, however it is acting like it is overgassed, but in fact it's the light buffer weight. The gun is running fast, and can be seen by closely inspecting the brass. This is also quite noticeable when comparing the recoil to other 308 AR platform rifles on the market.
And , AGAIN, I am far from the only person experiencing these issues. To this very day, PSA sells a buffer labeled as PA10 buffer, but it is from their GEN 1 rifles, and doesn't fit the gen 2 at all. They sell a PA10 buffer tube, but the internal depth is incorrect to properly fit the non standard length buffer spring they are shipping in all their gen 2 rifles, and AGAIN, this is all laid out in the thread I have linked in here at least twice now. I guess you are OK with the BCG slamming into the lower receiver every time the rifle is fired, and that's just fine right?

This is because there are multiple options for the buffer tube length/buffer length/buffer weight combo. You did not do your due diligence in ordering. Plain and simple, a buffer tube with the app. 8" internal length requires a 3.25" buffer and appropriate app. 12" .308 roundwire spring or a .308 flatwire spring. Better get an H3 buffer. Carbine length buffer tubes require a 2.5" buffer, H3 or heavy buffer equivalent and the appropriate spring. If you did not order the right parts, that's because you did your research AFTER ordering, when you had the fitment problem, not before you ordered. The information was out there at the time. That's entirely on you. If they sent you the parts you ordered, they did everything right.
And this was your fault, not PSA's. You ordered the wrong parts because you did not do your research as to what buffer tube/buffer length/spring works together. I had the same problem with mine, the buffer tube was about 0.01 too deep, so I dropped a few quarters into it before I ran the bolt even, let alone fired the gun. I knew this needed to be done because I researched the gun pretty extensively before purchase, because its a dang AR 308.
So once you fixed the mistake you made in ordering the wrong parts, the gun "is running and very accurate". So there it is. There was no problem with your PA10, there never was, and there is not a problem with it now. It is accurate, reliable, and functions fine. Anything beyond that is your personal preference.
Again, this speaks to your personal preferences only. If your brass is getting a little scratched up and recoil is more than you'd like....That's not an issue, thats a preference. An issue related to overgassing would be FTE's or FTF's.
The next guy might love that his bolt speed is high and his brass is getting flung into the next county. "Reliable", he might say. Not me, and not you, it sounds like.
As to your gun, It's running reliably, accurately, and has no function issues.
You aren't experiencing any issues.
congratulations. You now know what you should have known when you started your build. My buddy asked me why I paid to have an assembled lower sent, instead of just buying a receiver and a kit. This is why. Because PSA has a bunch of different options, they don't label them very well, and they don't hold your hand when you select whatever you are going to try to put together to make sure you know what you are doing. It's on you to know your depths, measurements, and lengths, and what works together.
I guess you didn't read post #29.
Now that the whole picture has kind of become clear, I still don't understand what your problem with your rifle is. Once you figured out what you were doing and got the right parts, it sounds like it runs great, and is accurate. If my rifle runs and shoots as good as you say yours does, for the $700 I spent on it and getting it sorted to my preference, I'll be more than happy.
If I were you, i'd spend more time shooting your perfectly functional and accurate rifle, and less time reading about other peoples problems that are ether overblown or self inflicted.

Nonsense. There is nothing "wrong" with the recoil system except for the fact that PSA needs to have about 1/8" shaved off of their buffer tube for it to time properly. I've acknowledged this is the biggest actual issue with their rifles currently. To complain endlessly about this when the solution is to literally take the buffer and spring out then drop a quarter or two down then reassemble is pedantic. Especially since all reports indicate its purely cosmetic and for the most part, hidden
If the gun feeds, fires accurately, extracts, ejects, and returns to battery without malfunction, and doesn't beat itself to death doing so, everything else is a matter of personal preference, period.
Now you are telling me the guns aren't overgassed? Its all in the buffer/spring combo?
Must be why AGB's are so popular with taming the PA10...because the buffer and spring are all wrong....
No, its an overgassing issue related to a standardized range of port sizes between manufacturers thats just too big. This causes the early unlocking, excessive bolt speed, excessive recoil, strong ejection, and battered brass people complain about. The heavy buffer and spring are just a way of mitigating this by adding inertia to delay the carrier from moving early, and the bolt from unlocking early without resorting to an AGB. It's still caused by overgassing, not "the wrong recoil system". This is why the rifle can be tuned to stop these behaviors with the simple addition of an AGB, and if you read up on it, this is why many people have had to add an AGB on top of a heavy spring and buffer combo. Because its a gas problem.
I prefer my rifle to unlock later, and eject softer, to save my brass for reloading. In that regard, an H3 buffer and flatwire spring will help to tailor the behavior of the rifle to my preferences. Doesn't mean the rifle is broken as it came. They would generally benefit with a heavier buffer than the H buffer they come with and I definitely prefer one, at least an H3, maybe I'll go heavier, and I agree that PSA should put at least an H3 buffer or an AGB on the PA10 for comforts sake and for the sake of my brass....but the recoil system as it comes is capable of functioning reliably just fine.
Or do you think only 25 people bought PA10's and they all went on AR15,com and ar308.com to complain about them? Sorry, I don't trust a handful of reviews from people who may or may not have a leg to stand on. There's some good info, but a lot of unwarranted negativity, people too lazy to do their research before having problems, and molehills made into mountains
I mean, look at you, your rifle runs fine, has since the first day you shot it, and is accurate, you've got everything I could hope for in a new rifle, I guess you just can't make some people happy.
And what about your gas tube problem? You ever going to enlighten us about how you know your perfectly functioning rifle has a gas tube that is too short?

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......
correct length Buffer tube - https://dsgarms.com/dsg-4201-0041
Buffer spring - https://dsgarms.com/armea1095
Proper weight buffer - https://dsgarms.com/dsg-4201-0048
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.
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. 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.

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.
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.
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.
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.

no comment from the peanut gallery on why if the PA10 is so well sorted, there are no less than 17 different Skus and 3 gas system lengths, and over 100 different youtube videos of people demonstrating the problems they are having with the PA10?
Also, I have at least 5 different email responses from PSA regarding the correct parts to order, BEFORE I even placed the order. I spent at least 2 weeks researching before I even ordered, since there was so much confusion. I would have ordered a completed lower, but they hadn't had any in stock for months at the time. PSA themselves didn't know what parts to order to build THEIR rifle.
It was a result of their interaction with myself, that led them to finally create a PA10 buffer kit, to reduce the confusion.
https://palmettostatearmory.com/psa-pa10-buffer-tube-assembly.html
That kit did not exist last year when I built my rifle. Also note, it still is not containing the correct H3 buffer weight, which will result in heavy recoil and improper gas timing. It will function, but not be running as it should.

Here is what will happen on most of them if you don't either address the bad recoil system, OR stick quarters in the buffer tube.

Hmm, so you are arguing that PSA hasn't gotten the PA10 sorted because they offer a good variety of uppers in various gas system lengths? That's an....interesting...argument.
There are 3 gas lengths, congratulations, you've figured out one of the most basic types of variance of the AR platform. But guess what. Its pretty much sorted out at this point. Most people at least somewhat familiar with the platform know the differences between them and know enough to match tube length to system length, including PSA. At the risk of sounding rude, this is really basic stuff, man, and your arguing that its still some kind of mystery as to how the different lengths work and that PSA hasn't gotten it figured out.....you really must be an "ar-newbie".
You are having trouble reading. I have acknowledged that the PA10 initially had teething problems resulting in unhappy customers. I have acknowledged this multiple times. I have acknowledged that PSA does not hold your hand when ordering parts...well, prior to you anyways.
Now, how many of those videos were made by people who assembled their own rifle, like you, and screwed up their parts purchases, like you? How many of those videos are complaints about minor issues I've already addressed? How many of those videos are done on older rifles that had issues PSA has since addressed?
How many video's did you find that were positive reviews of the PA10?
Ultimately, this argument is completely irrelevant given the amount of ignorant people like you putting together the wrong parts, and like you, complaining about self inflicted problems. Again, PSA assembled PA10 rifles and uppers are majority good to go, builds by ar-newbies often are not.
.
Wow, so they finally got tired enough of you stumbling around in the dark to take your hand and guide you through the process and took pity on the other ar-newbies unable to find their hind end in the dark. Congratulations. BTW, back when you ordered, a buffer tube with a 7 7/8" inside depth still took a 3.25" buffer, and a carbine length buffer tube still took a 2.5" 308 buffer. All of your complaints about the ordering process does not change that that you should have known these simple facts prior to ordering, and this is pretty easy info to find on your own.
As far as your rifle "not running as it should"...
Uh huh.
Yea? on PSA assembled rifles? I'm not finding much. Some builds by ar-newbies, ordering the wrong parts. Perhaps you mean this person who tried to put an Armalite pattern barrel on their DPMS pattern PA10?
"Using a Faxon 308 barrel (the one mentioned in my OP), and a PSA PA10 upper... midlenth gas tube (for midlength barrel) is NOT (NOT!!) the correct length."
https://www.ar15.com/forums/ar-15/A...0-upper-/121-711497/&page=1&anc=bottom#bottom
Or this guy, who like you, thought he had a short gas tube that looks exactly like the one you are telling us is too short, but actually wasn't?
"The gas tube looks short to me so I find an Armalite Gas Tube and order it. Then it dawns on me. Check the buffer and spring. I take a look at the and it seems awful stiff so I decide to slap on the carbine tube and buffer that came with my LBK. I charge the rifle and it is a huge difference. Now today I take off to the range to function check it. The rifle shot 60 rounds no problem. Full mag or half empty it ran like a sewing machine."
https://www.xdtalk.com/threads/pa-10-gen-1-lower-with-gen-2-upper.362457/
Here's a picture of that last tube that the guy thought was too short but actually wasn't.
Look familiar?
How many of those short gas tube builds were built by people who can read?
"For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers. We do not recommend using other manufacturers parts in our products."
https://palmettostatearmory.com
Yea, those were the only two cases I could find, and neither supports your theory that PSA is assembling rifles and uppers with gas tubes that cause function issues because of incorrect length. Maybe instead of insisting that it is so, you can link us up to actual discussions.
I see 6 random pictures of rifles that might or might not work just fine...pictures without backstory, testimonial, parts lists, or links even. How convincing. Given that I've shown you pictures of rifles that look exactly like that, that function fine, given that your own rifle looks like that and functions fine, this is a completely meaningless argument.
Oh, you've seen most of them? Well all right then, lol
Yea...and I can just as well say "here is what happens when an ar-newbie assembles a rifle using the wrong buffer and buffer tube"
Or "here's what happens when you run a wood rasp across the back of your receiver."
Pictures without context are just pictures.
I'll close with this. You don't know what you are talking about, posting context-free pictures and regurgitating a bunch of threads that you don't understand, don't link to, and that don't really don't support the point you are trying to make isn't going to convince me otherwise.
If I were you, i'd pause and reflect on the experiences you've had with your own rifle.
well, it's sub MOA, unless I flinch or a huge gust of wind comes along LMAO
Gun is now broken in well, and shooting very consistent. Not a single malfunction

Your implied lack of knowledge, along with the superior attitude you have is truly staggering and pathetic. I am done arguing the point. I have laid out what is wrong, and specifically why. Yet you continue to turn it around and imply it was all my own fault. Fact 1, my upper was a complete ASSEMBLED upper from PSA, not assembled by me. Fact 2, I showed several pictures of other assembled uppers from PSA as well. Now, open up any good quality 308 DPMS gen 2 platform rifle and look at where the gas tube protrudes to in the upper. You can also look inside any ar15 and notice the gas tube protrudes to the center of the cam pin cutout. You seem to know everything, so I guess you won't look.
Fact 3 - PSA was asked numerous times what specific parts to order from their website to assemble their rifle , as according to them, they use proprietary parts. When said parts are ordered it resulted in a gun that didn't work. Complete assembled rifles from PSA also exhibit recoil system problems, and short gas tubes.
Do the guns function? yes, absolutely. Do they function properly and timed well? Absolutely not. When the gas tube does not fully engage the gas key, it results in improper timing. PSA is using AR15 gas tubes, not ones made specifically for the DMPS gen 2 platform the PA10 was designed around. The gas tube needs to sit higher above the bore to enter the upper receiver, and the AR15 tubes have to be slightly bent to make them fit, resulting the tube being too short. This is solely a cost cutting move on the part of PSA. It works enough to cycle the gun, so they will never notice. Here is the PA10 part compared to the correct tube.
The correctly fitting armalite part is the bottom one in the picture.

The gas tube being 'short' would result in an undergassed rifle, not overgassed. So your rifle may well have shipped with a lighter than ideal buffer, but if it is cycling more violently, your assertions about the gas tube don't seem to hold up, but the buffer weight and receiver extension depth do.
Recoil may be significantly different between those guns for other reasons as well. Overall weight of the rifle, muzzle device, etc.
Many manufacturers are drilling gas ports in barrels on the large size because people take cheap ammo like Wolf and Tula that produces less pressure than quality ammo. A properly spec'ed gas port might not run on cheap underpowered ammo.
There is no excuse for that issue with the bolt carrier hitting the lower though.

Well, at least I know that there is no such thing as a perfectly running, undergassed and overgassed rifle, and i'm not bringing up peoples genitals as a topic of discussion.
Well, you aren't very good at it, so perhaps this is your best option.
No you haven't. You've regurgitated some random threads you found, many of which were home builds, made some baseless unsupported claims, then, without any real evidence whatsoever, painted a broad brush attack against PSA. You've painted mistakes you've made as mistakes PSA made, You've misrepresented mistakes made with other home builds as mistakes made by PSA. In reality, PSA was very helpful in getting your build running after you mistakenly ordered the wrong parts. They even made a kit for people like you after having to deal with your mistakes
It was your own fault. Man up.
Which is probably why it had all the right parts from the start and ran fine as is from the factory.
Yes, and as far as we know they run fine as well.
I don't know if you were aware of this, but PSA is not DPMS, and AR15's are not AR10's. You cannot compare one against the other. All you can do is ask "Does this rifle run correctly, or does it have short stroke or function issues"? If it does functions well without short stroke issues, you have your answer.
Yes, we've established that you didn't know enough about the compatibility between your buffer tube and buffer to order the right combination based on the specs. You know what I'd say to a PSA salesperson trying to sell me a carbine length buffer tube and a carbine length buffer for my PA10? "That won't work". But then, I know what parts to put in the shopping cart in the first place.
I've acknowledged the timing system issue, although I don't see it as nearly the issue that you do. The short gas tubes? You've yet to establish that statement as fact. You've yet to supply one example. You can't even use your own rifle as an example your supposedly short gas tube theory because your rifle functions fine. Dang, boy.
Dang. Just dang. When the gas tube does not engage the gas key enough, it results in short stroking.If your gun is short stroking, the carrier is not hitting the back of the receiver. Improper timing as we've been discussing it this entire thread is when the carrier hits the back of the receiver because there is not enough clearance between the bolt at full recoil and the back of the receiver. You do not know what you are talking about and your misunderstanding of how this rifle works is really starting to show.
Yea?
1. You got proof of that? Talked to PSA about that? Or is this just another regurgitated idea from some internet theorist?
2. Let's assume you are right. So what? Like I said, you have yet to provide a single instance of a PSA-assembled PSA10 having function issues directly related to too short a gas tube. If this is true, how do you know the PA10 isn't designed around an AR15 gas tube? PSA did make some deviations from the DPMS pattern, FYI. "Proprietary parts"....remember?
Ok, lets assume here that you are correct. Start finding me some function issues relating to your gas tube theory. Oh wait......
Well, I think that's about a wrap! Perfectly functional guns are indeed perfectly functional gunsSo, one perfectly functional part sitting above another. Gotcha.

Enjoy your sub MOA, perfectly functioning PA10

I apparently got lucky. I built a sidecharging AR10 late last year in 6.5 creedmoor which is a complete mixmaster with basically every part coming from a different manufacturer. I did have to exchange the stripped upper due to it missing a CNC cut which I found while unboxing, but other than that It all worked perfect with no fuss.
