Steyr AUG#Australian

The Steyr AUG is a selective-fire, bullpup assault rifle with a conventional gas-piston-operated action that fires from a closed bolt. It is designed as a Modular Weapon System that could be quickly configured as an assault rifle, a carbine, a submachine gun and even an open-bolt light machine gun.

The AUG is chambered for the 5.56×45mm NATO cartridge and has the standard 1:9 rifling twist that will stabilise both SS109/M855 and M193 rounds. Some nations including Australia, Ireland and New Zealand use a version with a 1:7 twist optimised for the SS109 NATO round. The submachine gun variants are chambered in either 9×19mm Parabellum or .40 S&W.

The AUG consists of six interchangeable assemblies: the barrel, receiver with integrated telescopic sight or Picatinny rail, bolt carrier assembly, trigger mechanism, stock and magazine. The AUG employs a very high level of advanced firearms technology and is made with the extensive use of polymers and aluminium components.

The AUG comes with a muzzle cap, spare bolt for left-handed shooters, blank-firing adaptor, cleaning kit, sling and either an American M7 or German KCB-77 M1 bayonet.{{Citation needed|date=March 2021}}

The AUG has a rotating bolt that features 7 radial locking lugs and is unlocked through a pin on the bolt body and a recessed camming guide machined into the bolt carrier. The bolt carrier itself is guided by two guide rods brazed to it and these rods run inside steel bearings in the receiver. The guide rods are hollow and contain the return springs. The bolt also contains a claw extractor that forms the eighth locking lug and a spring-loaded "bump"-type casing ejector.

The gas cylinder is offset to the right side of the barrel and works with one of the two guide rods. The AUG uses a short-stroke piston system where the right guide rod serves as the action rod, transmitting the rearward motion of the gas-driven piston to the bolt carrier. The left-hand rod provides retracting handle pressure when connected by the forward assist and can also be utilised as a reamer to remove fouling in the gas cylinder. The firearm uses a 3-position gas valve. The first setting, marked with a small dot, is used for normal operation. The second setting, illustrated with a large dot, indicates fouled conditions. The third, "GR" closed position is used to launch rifle grenades (of the non-bullet trap type).

The AUG is hammer-fired and the firing mechanism is contained in the rear of the stock, near the butt, covered by a synthetic rubber shoulder plate. The hammer group is made entirely of plastics except for the springs and pins and is contained in an open-topped plastic box which lies between the magazine and the buttplate. During firing the recoiling bolt group travels over the top of it, resetting the hammer. Since the trigger is located some distance away, it transmits its energy through a sear lever which passes by the side of the magazine. The firing pin is operated by a polymer hammer under pressure from a coil spring.

Some common criticisms of the rifle's trigger are the trigger feeling "mushy" and having excessive take-up. This is due to the relatively imprecise nature of how the trigger linkage is installed by the factory. The trigger can be "tuned" by the user in roughly 15 to 60 minutes with a 12 inch-pound wrench with a hex bit.

The quick-change barrel used in the AUG is cold hammer-forged for increased precision and durability, its bore, chamber and certain components of the gas system are chrome-plated (currently nitride on US market rifles). The standard rifle-length barrel features 6 right-hand grooves and a rifling twist rate of 228 mm (1:9 in). An external sleeve is shrunk on to the barrel and carries the gas port and cylinder, gas valve and forward grip hinge jaw. There is a short cylinder which contains a piston and its associated return spring. The barrel locks into a steel insert inside the receiver through a system of eight lugs arranged around the chamber end and is equipped with a folding vertical grip that helps to pivot and withdraw the barrel during barrel changes. The most compact of the barrels has a fixed vertical grip.

The receiver housing is a steel-reinforced aluminium extrusion finished with a baked enamel coating. It holds the steel bearings for the barrel lugs and the guide rods. The non-reciprocating plastic cocking handle works in a slot on the left side of the receiver and is connected to the bolt carrier's left guide rod. The cocking handle has a forward assist feature—alternatively called a "silent cocking device"—allowing the user to fully push the bolt home without racking the charging handle. A bolt hold-open device locks the bolt carrier back after the last round has been fired. The newer AUG A3s feature a bolt release button; prior to this development, all AUGs and the USR required the user to rack the charging handle to disengage the bolt hold-open after inserting a fresh magazine. Older versions of the AUG can be upgraded to use the newer A3 stock and hammer pack.

The rifle's stock is made from fibreglass-reinforced polyamide 66. At the forward end is the pistol grip with an enlarged forward trigger guard completely enclosing the firing hand that allows the rifle to be operated with winter gloves. The trigger is hung permanently on the pistol grip, together with its two operating rods which run in guides past the magazine housing. Behind that is the locking catch for the stock group. Pressing this to the right will separate the receiver and stock. The magazine catch is behind the housing, on the underside of the stock. Above the housing are the two ejector openings, one of which is always covered by a removable strip of plastic. The rear of the stock forms the actual shoulder rest which contains the hammer unit and the end of the bolt path. The butt is closed by an endplate which is held in place by the rear sling swivel. This swivel is attached to a pin which pushes in across the butt and secures the plate. There is a cavity under the buttplate that holds a cleaning kit.

The AUG's receiver can be changed from the standard model with a carrying handle and built-in 1.5× optical sight to the 'Special Receiver' which has a STANAG scope mount to allow for the use of a variety of scopes and sights. In later models (A2 and A3), it has several different types of receivers with Picatinny rails.{{cite web|url=https://steyrarms.com/steyr-aug-a3-m1.html|title=Steyr AUG A3 M1|work=steyrarms.com|access-date=11 August 2016|archive-url=https://web.archive.org/web/20170210045813/http://steyrarms.com/steyr-aug-a3-m1.html|archive-date=10 February 2017|url-status=dead}}

The AUG has a 1.5× telescopic sight that is integrated with the receiver casting and is made by Swarovski Optik. It contains a simple black ring reticle. The sight cannot be set to a specific range but can be adjusted for windage and elevation for an initial zero and is designed to be calibrated for 300 m. It also has a backup iron sight with a rear notch and front blade, cast into the top of the aluminium optical sight housing, in case of failure or damage to the primary optical sight. The sight is also equipped with a set of three illuminated dots (one on the front blade and two at the rear) for use in low-level lighting conditions. In order to mount a wide range of optics and accessories, a receiver with a NATO-standard Picatinny rail and detachable carrying handle was also developed and introduced in December 1997. Modern AUGs are equipped with, or can have the Picatinny rail swapped out with, an A3SF 60mm height x3 optic with optional riser and additional crosshair within the "donut" black ring. This specific optic can be piggybacked with other optics on top, as is the norm with Austrian special forces, due to the Picatinny rail included on top of the optic.{{cite web |url=https://steyr-arms.us/product/aug-optics/ |title=AUG Optics }}

While the AUG is not fully ambidextrous, it can be configured to be used by left- or right-handed operators by changing the bolt to one that has the extractor and ejector on the appropriate side and moving the blanking plate to cover the ejection port not in use. However, there exists also a right-hand-only stock that allows for the use of STANAG magazines.{{cite web|url=http://steyr-aug.com/Am161.jpg|url-status=dead|title=Steyr Daimler Puch AG|archive-url=https://web.archive.org/web/20141026033320/http://steyr-aug.com/Am161.jpg|archive-date=2014-10-26|access-date=2023-08-19|format=jpg}}{{cite web|url=https://steyrarms.com/accessories/aug/aug-stock-sa-black.html|title=Steyr AUG NATO Conversion kit – AUG Accessories – Accessories|access-date=14 November 2014}} {{Dead link|date=June 2018 |bot=InternetArchiveBot |fix-attempted=yes }}

Until March 19th, 2025, the NATO stock did not have a bolt release next to the magazine. To release the bolt after emptying the magazine, the user would need to remove the empty magazine, insert a fresh magazine, pull the charging handle back and release.

With the updated NATO stock, the user can release the bolt using the bolt release next to the magazine well.

The AUG is fed from a detachable proprietary translucent-polymer double-column box magazine with either a 30- or 42-round capacity.{{Cite web |date=February 2019 |title=STEYR ARMS Military & Law Enforcement 2019 Catalogue |url=https://www.winchesteraustraliamle.com.au/ts1661394200/attachments/Category/93/LEandM2019.tag.catalogue.pdf }} Optional NATO stock for STANAG magazine compatibility is also available.{{cite web|url=http://www.steyr-mannlicher.com/uploads/media/STM_Produktblatt_AUG_A1_A2_press_01.pdf|title=STEYR AUG A1 / A2|access-date=14 November 2014|url-status=dead|archive-url=https://web.archive.org/web/20120430052543/http://www.steyr-mannlicher.com/uploads/media/STM_Produktblatt_AUG_A1_A2_press_01.pdf|archive-date=30 April 2012|df=dmy-all}}

The AUG's firing mechanism can also be changed at will, into a variety of configurations, including semi-auto and full-auto, semi-auto and three-round-burst, semi-auto-only, or any other combination that the user desires.Jane's Guns Recognition Guide, Ian Hogg & Terry Gander, HarperCollins Publisher, 2005, pp. 273 and 361 It can also be converted into an open-bolt full-auto-only mode of fire, which allows for improved cooling and eliminates cook off problems when the AUG is used as a light machine gun.

The AUG features a progressive trigger (pulling the trigger halfway produces semi-automatic fire, pulling the trigger all the way to the rear produces fully automatic fire), and a safety mechanism (cross-bolt, button type) located immediately above the hand grip. In its "safe" position (white dot), the trigger is mechanically disabled; pressing the safety button to the left exposes a red dot and indicates the weapon is ready to fire. Some versions have an ALO or "automatic lockout", a small projection at the base of the trigger. This was first included on the Irish Defence Forces variant of the rifle, and soon after, the Australian Defence Forces variant. In the exposed position, the ALO stops the trigger being squeezed past the semi-automatic position. If needed, the ALO can be pushed up to permit automatic fire.Manual of the Steyr rifle, Irish Defence Forces

The AUG features quick detachable barrels and are available in different lengths; including a {{convert|382|mm|in|0|abbr=on}} compact length, {{convert|417|mm|in|1|abbr=on}} carbine length and {{convert|508|mm|in|0|abbr=on}} standard rifle-length. The muzzle device primarily used for these barrel lengths is a three-pronged, open-type flash suppressor. The flash suppressors are screwed to the muzzle and internally threaded to take a blank-firing attachment. AUGs equipped with the {{convert|508|mm|in|0|abbr=on}} pattern barrels produced for military purposes are also equipped with bayonet lugs. The {{convert|417|mm|in|1|abbr=on}} and {{convert|508|mm|in|0|abbr=on}} barrels are capable of launching NATO STANAG type 22 mm rifle grenades from their integral flash hiders without the use of an adapter. AUG barrels can also mount 40 mm M203 or AG36 grenade launchers. Steyr also offers {{convert|508|mm|in|0|abbr=on}} barrel configurations fitted with a fixed, post front-sight used on the rifle version with aperture iron sights.Ezell(1993) p. 224 A {{convert|621|mm|in|1|abbr=on}} heavy barrel with an integrated lightweight folding bipod with a closed-type ported muzzle device (combination of flash suppressor and compensator) is also available, primarily used on the AUG HBAR.

Because this extra railed section needed to be removed to strip the rifle for cleaning, the left side featured a quick detach lever. Due to the concerns over the extra cost and weight, along with potential issues with the reliability and consistency of the detachable handguard, the prototypes received little interest and were last seen promoted by Steyr in 2008.{{Citation |title=The most desirable AUG - Steyr AUG A3 CQC | date=21 August 2020 |url=https://www.youtube.com/watch?v=kueCU9QB_M8 |access-date=2023-05-15 |language=en}} In 2012, the American company PJA obtained the five original prototypes from Steyr and reverse engineered them in order to produce a US-made AUG A3-CQC and conversion kits.{{Cite web |title=AUG A3-CQC |url=http://www.steyrauga3cqc.com/ |access-date=2023-05-02 |website=www.steyrauga3cqc.com}}

The Steyr AUG HBAR (Heavy Barrelled Automatic Rifle), also known as the AUG LMG (light machine gun), is essentially an automatic rifle variant of the AUG. It features a heavier and longer {{convert|621|mm|in|1|abbr=on}} barrel with an integrated bipod, and the standard AUG receiver with 1.5× magnification scope. It fires from an open bolt to be more suitable for sustained fire, mitigating accidental cook offs. To accomplish this, it uses a modified bolt carrier, striker and trigger mechanism with sear.

• The Steyr AUG HBAR-T (Heavy Barrelled Automatic Rifle-Telescope) is similar to the AUG HBAR, but features a special receiver with a STANAG scope mount system usually fitted with a Schmidt & Bender 4×25 or Kahles ZF69 6×42 optical sight.

In 2014, the Irish Army began a modernisation programme to upgrade their Steyr AUG A1s, which was possible due to the modularity of the AUG. The result was the Steyr AUG Mod 14, and on the same year the army began issuing the rifle to its operational units.{{Cite web|title=Platoon Weapons|url=https://www.military.ie/en/who-we-are/army/weapons/platoon-level-weapons/platoon-weapons.html|access-date=2021-05-11|website=Irish Defence Forces|language=en}}

They replaced the original A1 housing/receiver group (with 1.5× optical sight) with an A3 housing/receiver group (with a Picatinny rail on top and right side) allowing a modern optical sight to be fitted. The Trijicon ACOG 4× sight was selected as the new optical sight of the rifle. The rifle features the ALO "automatic lockout" trigger, which can also be found in the Australian and New Zealand variants.

The New Zealand Defence Force adopted the AUG A1 model, designated Individual Weapon, Steyr (IW Steyr) as its primary individual weapon. 5,000 Austrian made rifles entered service in 1988, later supplemented by a further 15,000 manufactured in Australia by ADI.{{cite web |title=Personal Weapons - Steyr Rifle |url=http://www.army.mil.nz/our-army/equipment/weapons/default.htm |url-status=dead |archive-url=https://web.archive.org/web/20091218164455/http://www.army.mil.nz/our-army/equipment/weapons/default.htm |archive-date=18 December 2009 |website=New Zealand Army}} In 2013, Stuff reported that New Zealand had 13,000 IW Steyrs.{{cite news |last1=Schouten |first1=Hank |title=Defence seeks upgrade for 25-year-old rifles |url=https://www.stuff.co.nz/dominion-post/9144617/Defence-seeks-upgrade-for-25-year-old-rifles |access-date=9 May 2023 |work=Stuff |date=10 September 2013}} In 2015, New Zealand selected the Lewis Machine and Tool Mars-L 5.56mm rifle to replace the IW Steyr and began transitioning to the new rifle in 2017.{{Cite news|last=Lawrence |first=Kirsty |url=https://www.stuff.co.nz/national/93704972/new-59-weapons-package-begins-defence-force-rollout|title=New $59 million weapons package begins Defence Force rollout|work=Stuff |date=15 June 2017 |access-date=9 May 2023}}{{cite web |title=Individual Weapons Replacement |url=https://www.defence.govt.nz/what-we-do/delivering-defence-capability/defence-capability-projects/individual-weapons-replacement/ |website=New Zealand Defence Force |access-date=9 May 2023 |date=January 2021}}

The variants of the New Zealand IW Steyr were equipped with a progressive trigger (without full-auto lock-out tab as seen on F88 models) and a three-position safety. The sight added a crosshair to the circle reticule. New Zealand issued both factory and locally modified carbines alongside the full-length rifle variant.{{citation needed|date=July 2020}}
