Yeah, there’s no fucking way I’m buying one of these now it’s definitely a long-term project to own one but it’s gonna have to be a new gun down the line if they get their shit in gear since I only like the new style rail. I’m just wondering how long it’s gonna take for people to stop buying these.

Someone please tell me more about this part, because (after Sabre) I always heard it was FN that was manufacturing the chrome-lined A3 & A3 M1 barrels for Steyr, and that FN produced the "bad batches" where the chrome started flaking off prematurely.

Is that incorrect?

That’s what I heard. Which is also crazy right because when did FN ever fuck up a barrel? Something is off with Steyr’s whole operation as far as I’m concerned.

They cannot. They can only import unchambered blanks. The machining. Including the chanber, has to be done in the US.

And lest we forget, Steyr US also made the switch away from CL without saying a word and continued to advertise the rifle as having a CL barrel well after making the change.  I don't know for sure, but I seem to recall that nitriding a barrel costs less than CLing a barrel.

I have a thirty five year old AUG with two stocks and neither are cracked.

I am aware this discussion is focused on the recent manufacturing problem afflicting these stocks but I added this info above in case anyone was wondering about longevity of vintage AUG stocks.  I have replaced a flat spring for the takedown button in all this time, about ten years ago.  No problems since.

I don’t think they ever broke until the change in the material. The problem is not that they fucked up. The problem is they ran with it and are still running with it I don’t know what the fuck they are trying to do other than to run this thing into the ground.

It looks like it’s just the top that’s got sharp corners. I wouldn’t fuck with it if it were another gun, but the way they… Handwork the stock… I don’t think it can make it any worse.  Somebody, not here, suggested to me that they don’t believe the black ones are breaking.

Hard to read but i will guess that’s the material code not the date. Where i work parts have two marks, kinda similar loking, one for date one for material. On the date, there is an outer ‘wheel’ with months 1-12, you rotate the inner circle with arrow to indicate to a month, and there js a two digit year on the sides of the arrow.

Those manufacturers are not importing barrels. They are importing sporterized rifles that are converted once in the US. There is a difference. Non-sporting barrels can’t be imported on their own.

On one hand it’s unfortunate that that Steyr didn’t import sporterized bastard rifles and convert them once stateside. On the other hand it’s far safer to have manufacturing in the US.

And with all that said, it’s really unfortunate that Steyr doesn’t make correct chrome lined barrels in the US.

I think there shouldn't be a restriction in the first place. Allegedly the lobbyists for some of the big domestic firearms manufacturers supported it in 1989.

Steyr seems to not be as innovative at executing workarounds as IWI, Benelli, and FN for example. (I think they're a much smaller company though.)

Not only is the ATF inconsistent and arbitrary about what form 6's are approved, they have especially been unfriendly to Steyr over the years. A great example would be in 2013 when Steyr was approved to import AUG 9mm kits with Austrian barrels, then shortly after ATF changed their mind and said the Austrian barrels were 'non sporting'. The ATF similarly allowed IWI to import Tavor 9mm and 300 BLK barrels and rifles for years, but changed their minds in 2022. Its also worth noting that the Steyr AUG is specifically named in the 1989 import ban, so there's another bureaucratic obstacle for Steyr.

The barrels can be imported only if either a pistol or “sporterized” rifle has been imported. Pistols are exempt from 925(d)(3) and so are their barrels. A rifle that is imported as readily suitable for sporting purposes can also have barrels imported.

Steyr has neither of those as options.

Well, there is the AUG Z SP.  

Manually operated, so no gas system, and you'd assume very "sporting" being a straight pull repeater.

So it’s been. Asked a few times, and threads I read don’t seem to get accurate replies as people either don’t list the stock colors of the ones breaking or when they say they have a problem with a black Aug, it’s not exactly a crack being described.

Does this affect BLACK  Augs? Or just white/mud, etc?

I had thought the answer was yes, but now going back and reading posts and threads I’m not sure I’ve seen any or if any, more than one instance of black/aug mag stocks breaking.

So would you say black augs are immune or less prone to crack, or not?

Emailed SAI over the weekend and got a reply back first thing this morning...mine was manufactured on 8/25/21. Was hoping for a pre-cracking-issue gun, but I'll run it like usual until it does (if ever). Is so, I'll just drop by one day and swap it out...luckily, they're only 20 minutes from my work.

General rule was black is always the strongest blend.. in 2024 I’m sure things have changed and the advancement in polymer tech made colored polymers as strong as black one.
The new translucent Pmag is a good example.

point is they can make it happen if they wanted just like they could offer domestic chrome lined bbls if they wanted but they aren’t concerned the US AUG aren’t built to the same standards & specs the Austrian AUG are.

That’s correct. I was told it had to do with the barrels being straightened after chrome lining, which caused microscopic fractures in the chrome lining, premature failure/spitting of the chrome. I have no way to verify if this is accurate.

True. And it’s a shame they don’t. They presumably still have the molds for the USR stock and as was previously mentioned the straight pull AUG Z for the UK market has potential. It would be pretty simple to import bastard sporters and convert stateside.

The point I was making was that it’s not just a simple matter of importing correct Austrian AUG barrels.

Same thing is happening to the U.S. made scars.  I think it might be more of a FN USA QC issue. The early FN AUG bbls were almost as good as the Austrian bbls the later ones were sloppy.

To chrome a barrel u run an electrode - a metal rod - through the center. If the barrel is bent, even if u dont touch the bore, the chrome is going to be uneven. As far as it the cracks, chrome already has micro cracks naturally. I absolutely do not see the kind of slight bow that would allow you yo still be able to process it for chrome, creating a problem with adhesion during straightening. Idk why someone would try to chrome a crooked barrel before straightening it.

Just took my AUG apart. Looking at the date code, the arrow is pointing to “2” with a 2/1 below it. I’m guessing manufactured in February of 2021?

Would my stock be in the range of potential issues?

ETA: Looks like it could be but I also haven’t heard of any black stocks cracking.

Just put my Aimpoint pro on it this morning. Will probably take the BUIS off but wanted to throw them on there. Also removed the spacer on the Aimpoint after I took this photo.

I absolutely do not see the kind of slight bow that would allow you yo still be able to process it for chrome, creating a problem with adhesion during straightening. Idk why someone would try to chrome a crooked barrel before straightening it.

Exactly.  And this was second hand info, so take it with a grain of salt.

I was told that FN was turning the O.D. contour too quickly, resulting in a slightly warped barrel. The individual who told me this is a barrel maker with lots of experience, including with chrome lined barrels. Again, second hand info.

ETA: Looks like it could be but I also haven’t heard of any black stocks cracking.

Just put my Aimpoint pro on it this morning. Will probably take the BUIS off but wanted to throw them on there. Also removed the spacer on the Aimpoint after I took this photo.

Don’t you nean a 2 to the left of the arrow, and 1 to right? That would be a typical dateclock core.

While I have a NATO stock installed on my A1… I still have the original OD green steyr stock… was looking at it today and noticed the same markings.
My A1 was mfg in 2005 iirc

My guess is that nobody bothered to order a new date clock insert at some point.. probably after 2000.
We used to do the same in my old job.

Called over-engineering or “safety factor” in the design world.

And yes, sharp corners are a design flaw generally.  Why build in a potential failure point, when you could have radiused each corner instead?  Not exactly a new concept either.  They might not all be breaking at a corner, but sure as hell most are.  

Steyr didn’t radius out the sharp corners (looks like by hand) on the newest stocks they have been shipping just for the hell of it.  They know that is the most likely place it will start, and by removing the sharp corner will help prevent it from starting.

I sure would (and did on mine, made it match the later one I got).

You missed the point. It’s not a “design flaw” if it worked for decades. It’s bad polymer. Let’s call it what it is. They weren’t rounding corners for decades due to a design flaw. They wouldn’t even be doing it now if there wasn’t a polymer issue.

I’d also add that polymer acts differently from metal… rounded corners may not be that necessary with polymer since it can flex and absorb shocks better.

I’m not an engineer though

My OD stock date code is '22 so I guess I'm going to die as a result of a catastrophic stock failure while LARP'g around my mom's basement in search of Cheetos and Shasta.

Exactly. Rounding sharp corners is a good design practice (maybe the old material was so strong that it wasn't necessary), but they started doing it only recently and that coincided with the materials change and stocks cracking.

That is called a mitigation, not a solution.

It could happen.
