The Aug trigger was made to be able to shoot with winter gloves on. It's heavy, spongy pull was intentional for this reason as well as for safety reasons. And it was meant to make a 4 position (safe, semi, burst, auto) system more intuitive by having semi always be an option with the half pull, and then all you have to do is alternate between burst, and auto. But yeah, it could have been way better. Not bad for something that came out in the 70's tho.
Great video! It got into technical details that are beyond me but you did a great job explaining. I really appreciate your giving us the technical reasons why we feel what we do when pulling the trigger on a Styer AUG. Thank you! Hope you keep making videos. Oh, and your CAD images were the clearest I have ever seen in a firearms video. I could easily see and understand what was happening in the inner workings of the firearms you discussed!
Congratulations! Neat video in length and thanks for the sources. I have an SA that should be A2 based but lacks the anti-rotation device for the firing pin. I wonder if if it would fit. Mine was sold with a 20'' barrel via Oberland Arms for sport shooting. When cocked I have no pre-travel, there is just a heavy wall. What components should be kept handy to replace parts over decades of use? There is/was a fantastic trigger from Austria only using a cam replacing only the trigger. The owner of kawatec made videos on the overall component weight as well and only sold his triggers (that lower the weight) only when the rifle was shipped for the install and tuning. Sadly I couldn't order when it was available based on export restrictions and I'm not Austrian.
From what I understand, the AUG overall will last a very long time before parts will need replacing, this is one of its strongest benefits. I've read a lot of reports from other people on forums and social media groups with full autos with a minimum of 50k rounds and have not found the need to replace anything but a extractor or bolt sleeve, some other small parts as well but nothing that's detrimental. I've had my pre-ban A1 (semi-auto only, I'm not that rich lol) since the late 80s, and I can't tell you the exact number of rounds I've fired through it, but considering I've brought it to the range A LOT since buying it, letting tons of people fire numerous mags in a single range trip, along with numerous other variables, I'd say I have at least 80K through mine. Over the decades I've only had to replace 2 extractors, 1 front grip pin, and 1 bolt sleeve. The newest A3s since 2020 have had some spotty issues with the polymer used in the stocks, but considering yours is an A2 I wouldn't worry about it one bit.
There is "supposed" to be some play in the trigger rod setup, so that the rod ends do NOT rest on the "sear". There was a lot of "official consternation" when it was discovered that some of the more "creative" operators were playing with the the rod clamping screw to pre-load the sear: VERY DANGEROUS. If anyone wants to "slick" an AUG trigger, first ensure that the above-mentioned dangerous trigger situation does not exist.. Then disassemble the firing mechanism pack ane apply either graphite or Molybdenum Disulfide powder to all the "engaging" surfaces in the pack NEVER "adjust" ANY engaging surfaces in these packs. Another problem that occurs is if the troops use excessive oil on the metalwork and then the rifles are placed in an armoury, butt DOWN. Oil ends up in the trigger pack. oil retains dust, forming a nice grinding paste. It also rots the thin rubber bull pad. That "drop safety" had to have been designed by a committee. Drop a loaded rifle on its nose and, in the unfortunate event of a "discharge", the bullet will go downward. Harking back to open-bolt sub-machine guns of dubious parentage, weapons dropped on their butts are potentially likely to discharge UPWARD, where people may be standing. NOT my favourite military rifle, despite its handy size and accuracy performance..
I appreciate the explanation behind the design of a heavy trigger spring! I wonder if it would have been better to build in a grip safety for the AUG similar to that found on a 1911.
There must be some mistake in all those AUG examples, looking at the geometries it seems obvious to me that the designers intent was to have the drop safety lever work both forwards and backwards which also aligns with what makes sense generally speaking.
At first I thought that as well, but both the 3D model and the videos I saw show the spring only pushing the lever up. And the 3D model is also a bit wrong. In the real life examples, the top edge of the sear slot goes back much farther than the bottom edge, and it's already above the safety lever when the sear is fully forward. There is no way the safety lever can pop up behind that edge and block it
@@cabbage6015 I simply cannot believe that the drop safety would not function in the principal direction where an accidental firing is the most likely upon impact. Perhaps there's something wrong with Steyr engineer brains?
@@oddspaghetti4287 I've tested the drop safety a couple times from shoulder height out of curiosity with my A1 and 3rd gen MSAR clone (both with muzzle down and buttpad down) and neither one have seemed to release the hammer on accident. From what I see when I have the actual trigger pack in front of my face, the drop safety is actually quite sensitive, as it doesn't take much movement at all for it to engage the sear and block it (I measured about 1mm of movement from the top of that "lever", maybe a little less, for mine). The spring also is quite weak, so when you combine the design of the weak safety spring and short amount of travel necessary to engage the sear, it's able to move where it needs to no matter which direction you drop it. Now I'm sure there's some examples of the drop safety NOT working, but so far I haven't heard anyone make complaints about it.
AUG/F2000/P90 triggers are indeed terrible. However, shooting a full-auto P90 was something of an epiphany for me. A gun that made literally zero sense in the form of the 16" semiauto PS90 made soooooo much sense as an SBR full-auto gun with a progressive trigger. I totally understand why the USSS adopted the P90, and it's kind of a shame that they've moved away from it in recent years.
I like their new wlvrn more. I think it’s one of the best bullpup rn from the user’s point of view, although I have doubts about its engineering. I also recently purchased an X95 which I’m pretty happy with
Babe wake up. Cabbage uploaded
Great to see you back with another gun mechanics video! Thank you very much for sharing! Congrats on your marriage!
Thank you!
What a wonderful little video, still an AUG-fan but I commend you for the level of detail you manage to convey in such a short time.

And it was meant to make a 4 position (safe, semi, burst, auto) system more intuitive by having semi always be an option with the half pull, and then all you have to do is alternate between burst, and auto.

the homie's back!! ayurrrrrrr
Do you know if the Australians modified their AUSTEYR to mitigate this apparent issue?
As far as I can tell, no: ruclips.net/video/KWp9r0MEfyI/видео.html

how does factoring in the new Steyr trigger springs affect the assessment? They drop the pull weight down to around 6 lbs and still keep it drop safe
There's a guy names Titus who makes an Aug trigger pack with ar15 components and it makes the trigger pull wayyyyy better
SAR21 (Singaporean Bullpup) uses a modified Eugene Stoner's trigger, what do you think about it?
I haven’t seen any clear diagram on how it works so I’m afraid I can’t say
Awesome, thank you, I knew physics favors bullpup
Please be consistent for your fans bro

Have you had a chance to check out the F90 mechanics? One of my favorite bullpups and now I‘m curious about the trigger.
As far as I can tell, the Australians didn't change anything in the trigger pack: ruclips.net/video/KWp9r0MEfyI/видео.html
Can I find blueprints for all of the parts of the trigger group, by the way? Looking to build an AUG and I’d like to observe the design better
@@whiteb01summer I don’t have the blueprints, but all the 3D models in this video are from a game called World of Guns if that helps
@@cabbage6015 Cool
I'd like to see your take on the K&M Arms M17S. The trigger is only 4lbs, and if it's like the Bushmaster that came before it, should be great.

Now comrades, all salute the firearm king and queen 🎉🎉🎉🎉
Phenomenal video! I have an AUG 🤣👍

I love you and i miss you

More QBZ commentary please 🙏🏻
kinda ran out of things to say about the QBZs haha 😅
@@cabbage6015 QBZ-81? But I'll still watch whatever you make lol
Having shot a RATWORX equpped AUG, I can confidently say that it is STILL worse than my Hellion trigger. Truly, a terrible trigger design.
And the hellion trigger is fucking bad
Great channel. Glad i found you.
