The F88 Aus Styer

The Australian Defence Force issues the F88 Austeyr to Australian soldiers as their Individual Weapon (IW). The weapon has been in service world wide since the 1970s and was introduced to the Australian Army to replace the SLR.

There are various configurations of the F88 available for different purposes. These include different barrel lengths for sniping or close quarter fighting, different optic sighting systems including night vision, and grenade launchers.

The Steyr broken into parts

The Steyr broken down into its main groups.

STEYR AUG A1

Steyr's newest offering, the AUG (Armee Universal Gewehr), is a space-age assault rifle with many appealing features. Based on the bullpup design, the AUG is chambered for the 5.56 NATO cartridge.

The AUG is an ambidextrous rifle as the bolt is replaceable and the ejection port may be moved to either side of the receiver. Even the carrying strap swivels may be repositioned for convenient port-side carry.

The AUG functions in a gas-operated, semi-automatic firing mode (in selective-fire configuration, it is the standard arm of the Austrian army). A gas-pressure adaptor has a shut-off valve located on the barrel with two settings-for firing under normal or adverse conditions.

This high-tech assault rifle employs a unique 30-round, lightweight magazine made of transparent plastic which leaves no doubt as to the number of rounds one has left. The one-piece, greenish-colored stock is made of a durable plastic and houses the receiver group, hammer mechanism and magazine well. The pistol grip is integral with the stock, and a cross-bolt safety that locks the trigger is conveniently located just above the "rest" position of the shooter's right thumb.

Three interchangeable barrel lengths are available-a 20-inch tube is standard while 16 and 24-inchers are optional. The cold hammer-forged barrel is chrome-lined and locks into the receiver by rotating it 1/8th turn. The forward positioned folding pistol grip is utilized to provide a handle to remove hot barrels which may be plunged into water for immediate cooling without suffering any consequences. A flash hider is attached to the muzzle.

What appears to be a top-mounted carrying handle doubles as a 1.5X scope that has full windage and elevation adjustments. The AUG quickly and easily breaks down into six basic component parts groups.

With the switch toward a heavier 5.56mm bullet, the AUG is ready with a barrel which has six lands and grooves and a right-hand twist with one turn in nine inches, which better stabilizes the heavier projectile. The lighter bullet - 55 grains - is better suited to a one in 14.

The AUG is futuristic in both design and concept. It seems to have solved many of the inherent problems with assault rifles, mainly overall size and weight. With the 20-inch barrel snugged into place, the AUG measures a compact 31 inches long and weighs just a shade under eight pounds...

AUG 9mm

Taking advantage of the AUG's modularity, Steyr engineers have designed a kit which allows the user to convert an AUG into a 9mm carbine without the use of tools. The kit consists of a barrel group, bolt group, 25-rd magazine, and magazine adaptor. The carrier assembly differs from the .223 version in that it does not require the use of a rotating bolt. Also, the bolt allows only for right-handed ejection, so the stock's port cover must be situated accordingly on the left side. The magazine adaptor emulates the top of a .223 magazine and remains affixed to the stock during magazine changes. It contains its own bolt hold-open actuator which is triggered by the 9mm magazine follower. Because it utilizes the blowback principle, there is no gas port or piston in the 16" barrel assembly. A 9mm AUG measures 665mm (26") in length and is 3/4 of an inch shorter than an HK MP5A2 which uses only an 8.85" barrel. Without a magazine, the AUG 9mm weighs approximately 7 lbs. as opposed to an MP5A2 which weighs 5.9 lbs. However, while the MP5 seems to have been adopted by every worthwhile military force and law enforcement agency worldwide, it is estimated that there are less than 175 9mm AUG conversion kits in the U.S.

STEYR AUG HBAR

AUG HBAR-T

Steyr is a rather progressive company which, while continuing to produce high-quality arms of traditional design, is always at the forefront of advanced development as well. Having already been responsible for producing the highly-touted 5.56mm AUG assault rifle, it didn't take long for the Austrian firm to come out with a companion piece designed for sniper applications. This is the AUG/HBAR-T (heavy barreled automatic rifle with telescopic sights).

The HBAR-T shares the assault rifle's synthetic stock of bull-pup configuration; however, the AUG's carrying handle cum optic sight has been deleted to make room for a scope base. The same Kahles ZF69 6x [commonly used on Steyr SSGs] is then fitted to the HBAR-T and the receiver thus modified is complemented by a 24-inch, cold hammer-forged heavy barrel with integral bipod.

The AUG/HBAR-T features all of the same prepossing traits which make the AUG system so appealing...
