My fingertips crack in Missouri winter weather. In that temp, I think my hands would shatter.

Just toss a couple hand warmers where the cleaning kit is stored and the AUG will be good to go.

I used to work in oil and gas completions, the system we used was rated to -20° F. We routinely operated in much colder conditions during the winter. I used to think that just because it worked in colder temperatures didn't mean that the system wouldn't one day just catastrophically fail... I've never seen anything near as cold in the picture above and I wouldn't trust anything to run right in those temperatures either. Car, electronics, gun, etc. nothing survives the cold.

At that temp, it's how much lube you have freezing everything together.
An AR, AK, or M1 would have no clear advantages. |

There's a reason the rifles used by the Canadian Rangers and Sledgepatrol Sirius in areas like that are bolt guns. Gunpowder operates differently at different temperatures, I expect temps that cold could be too cold to create sufficiently high pressures to run a semi-auto.

In AZ, mine crack at about 50. The colder it gets, the worse it gets. Something about a desert dry cold that just saps the water from everything. Like freeze drying. View Quote View All Quotes View All Quotes Quoted:

View Quote It's kind of funny, of all the guns I have (well, had - sold it), the only one that was true 100% correct with an as-issued military primary-service rifle still in modern service - is the M1917 bolt action rifle that is a 102 year old rifle. |

The polymer used for the AUG stock is a 30% glass filled PA66 if I recall correctly.. great for high temps applications but can also handle low temp like -40 Celsius or so.. not sure on the exact value..
Don’t know it the trigger pack is made of the same material |

View Quote From that perspective I would expect an AR or AK to have the advantage as for both they would be easier to remove the oil from various moving parts. Can’t very well go removing the AUG thrust caps in the field to clean off all the lube. From there you would need to know the Tg or glassy transition temperature for the various polymers used in the AUG. There are standards for measuring the brittleness temperature of various plastics under specific conditions and my guess is that Steyr has all that info, it’s just a matter of figuring out how to get it from them. My feeling is that the AK has the upper hand for any extreme cold in that all the most relevant bits are made of and held together by metal. You break a plastic grip on an AR and the selector detent thing falls out you have a minor problem that isn’t really gonna happen with an AK. I’m sure that military issue M4s are made out of particular polymers however it’s anybody’s guess what a lot of cheaper commercial stock sets are molded from. Several years back I had the butt stock on a PTR break in half in cold weather not even doing anything rough, went with real HK furniture after that. I guess if you wanted to make an “Arctic AUG” a first step would be a 2020 Precision hammer pack as I believe it is made entirely of metal. From there I would probably remove the thrust caps and lube the recoil springs with something known to be good at low temp. I would also look at getting a stock that only has a right hand ejection port as that little plastic cover on the ambi ejection port stocks seems like it would be a weak point. |

If any of you have a disassembled one maybe the markings are hidden somewhere.. -74 F must be a nightmare for the shooter even if the rifle is ok |

View Quote according to the 80's M16A2 TDP a blend of Zytel is used for the pistol grip. that is the patented Dupont's name for a glass filled PA66.. basically the same used on the AUG. data sheet available online show testing performed at -40F. |

Understood. Wish I could win the lotto.....it would be travel time! I gots ta know. Actually, I don't. It would be fun, however. View Quote As it is, Steyr isn't moving in any particular direction. They've been resting on their laurels for far too long. Let me tell you a story: once upon a time there was a gun called the prohunter. You could buy it for a reasonable price in nearly any flavor you could imagine. They were great, accurate, well built guns. Then Steyr decided to "discontinue" the prohunter. Now Steyr releases what they call a prohunter II in 3 calibers and market it as "an affordable gun for the American family". What does steyr consider affordable? $1200. nothing changed but for less options and a higher price. Meh. |

Yes, the AUG can take that I'm sure.
They do have mountains and cold weather in Austria. I've been a student in a carbine class with AR's at -20 and worse. So I'm sure the AUG can handle it as well as the ARs or better. I've shot M4's at -50 at Ft. Wainwright (Fairbanks, AK) playing Army games. I've mag dumped several mags in a row fast as I could in full auto from an AUG in 9mm and 5.56 for test firing purposes (no target, no sights, just does it run cause my nuts are freezing off) at -15 to -18. So I'm confident it would take it. tsh77769 |

That looks like Delta Junction, Alaska. Fort Greely is located nearby. Along with the missile defense function located there, the US Army maintains its Cold Regions Test Center there.
Now we know why they selected that location! |

This was in Alaska the other day. https://www.AR15.Com/media/mediaFiles/23042/brrrrr_JPG-1243019.jpg Down here in AZ, the worst I have to worry about is maybe a -5 to -10 degrees F in the high country. At the very worst. You guys think the hammer pack and the stock group could handle operating at such temps as -50 F or below???? Just curious. View Quote |

Here in north central Montana, within day trip distance of Glacier Park, temps below -40 tend to happen at least once each winter. I haven't heard any complaints from my buddy about his AUG and the cold.
My SAR has held up just fine. I have had certain polymer magazines that broke in the cold, but no issues with the rifle, itself. See-through polymer seems like a good idea for mags, but they don't seem as durable or temperature tolerant. |

Tikka Arctic bolt action in .308 is what you want in temps like that. That is what Canadian Rangers use after they retired Enfields (their version has a slightly different colored wood stock). Hard to find, but there are usually two or three on Gbroker. I own one. Pretty slick rifle.

Ruger is a good manufacturer, but Tikka is better, plus they have lot of experience with low temperatures.

Haven't shot an Aug in the cold.
But have shot plastic guns in -50 to -60 wind-chill. (Fs2000 which has an all plastic trigger pack.) Never had issues with any gun in the cold. Most cars are half plastic these days as well and I don't see them cracking from being out in the cold either. |
