Just saw this, thought it was interesting. A joint project between Steyer and Rheinmetall. Although the Article says its a variant of the AUG, it looks more like an AR spinoff. I'm guessing something was lost on translation and am thinking it was the piston gas system that was based of the AUG.

Rheinmetall and Steyr Mannlicher offer new RS556 assault rifle system

Two of Europe’s most respected defence companies, Rheinmetall and Steyr Mannlicher, have joined forces to manufacture and market the RS556 modular assault rifle. This German-Austrian cooperation project adds a key item to Rheinmetall’s growing array of infantry products.

The RS556 is based on the highly regarded STM556, which Steyr Mannlicher first unveiled in 2012. Outstanding modularity characterizes this easy-to-use, future-proof 5.56mm x 45 cal. weapon.

Rheinmetall and Steyr Mannlicher are offering the RS556 assault rifle as a jointly produced product, made in Germany, with a German valued added share of 60%. Among other things, the two partners thus have their sights set on the German market. This innovative weapon is a possible candidate for the new "System Sturmgewehr Bundeswehr": the German armed forces intend to replace their standard G36 assault rifle with a more advanced system starting in 2019.

Rheinmetall and Steyr Mannlicher each have well over a century of experience in developing and manufacturing infantry weapons. The RS556 project underscores both companies’ commitment to supplying military and security services around the globe with reliable, future-proof, state-of-the-art systems and equipment.

Featuring an adjustable short-stroke gas piston system and rotating bolt, the gas-operated RS556 is based on the tried-and-tested Steyr Mannlicher AUG, or Universal Army Rifle, a design concept that has proven itself in decades of service on every continent.

With a 16" barrel (406 mm) and a fully loaded, 30-round magazine, the RS556 weighs around 4.2 kilograms, just over 9 pounds. The adjustable-length light-weight stock clicks into seven different positions, meaning that operators can adjust the RS556 to match their individual equipment profile in optimum fashion.

In a matter of seconds and without tools, the hammer-forged barrel can be easily exchanged. This means that the RS556 can be readily modified for various missions.

A number of standard barrel lengths are available (14.5", 16", 18" and 20"); however, customer-specific barrel and rifling lengths can be easily created.

The RS556 features several standard and optional NATO accessory rails with receiver systems designed in accordance with MIL-STD-1913, STANAG 2324 and STANAG 4694. This means that the weapon can be fitted with various optics and night observation devices or laser light modules. A 40mm grenade launcher can also be mounted on the new assault rifle. Moreover, the RS556 is compatible with Rheinmetall’s modular "Future Soldier – Expanded System" (IdZ-ES), and can also be connected to other soldier systems.

A special breech system with an emergency operation feature ensures that the weapon always functions reliably even in extreme operating conditions, e.g. in severely hot and cold environments.
About the partners

Founded in 1889, the Rheinmetall Group is a tech enterprise specializing in mobility and security. Consisting of three divisions – Vehicle Systems, Electronic Solutions and Weapon and Ammunition – the Group’s Defence arm is one of the world’s foremost defence technology makers, supplying a wide array of advanced military equipment: from vehicle, protection and weapon systems to infantry equipment and air defence solutions to networked target engagement sequences and electro-optics and simulation technology. In the small arms domain, Rheinmetall has produced such renowned products as the G3 assault rifle and the MG3 machine gun.

Established in 1864, Austria’s Steyr Mannlicher has long been one of the great names in the European small arms sector. The company’s many technical achievements include the Werndl-Holub breechloading rifle, the Mannlicher straight-pull bolt-action rifle with en bloc clip, and the SSG69 sniper rifle. The Steyr AUG bullpup system is used by at least 37 nations worldwide. As the standard rifle of military organizations ranging from the Austrian Army to the Australian Forces, it has proven extremely effective in all climate zones. In addition, Steyr Mannlicher supplies modern sniper rifles such as the SSG08, the SSG Carbon and the .50 cal. BMG HS50M1. Likewise meriting special mention is the company’s GL40 40mm grenade launcher, which can be used in build-on or standalone mode.

I hope the german has some senses of not picking this over HK 416 just out of spite.

Ergonomic is 1 step back from the G36 and 2 steps back from the HK416. Give me a SIG 516 if they are so desperate to not go HK.

Sometimes you just can't stick something you have ( the AUG gas and barrel system) onto anything and call it a day.

I don't disagree with your confusion on why not go with the hk416. Iirc both the ksk and gsg9 are now fielding the a5 variant as a g38.

Although I am confused what you meant by the 1 step back from the g36 and 2 steps back from the hk416?

This looks like the same ergos of any ar pattern rifle including the 416.

Seeing the pedigree of the makers I expect this to be a good rifle. Although will it beat the hk416a5? I doubt it.


I do have to wonder why they don't just adapt the hk416/g38 as their issue rifle.
 
Such short hand guard and a giant exposed gas block. Not ideal for mounting Laser designator and illuminator. Little estate to work with and giant shadows. Like the AUG, you can grab the gas block by mistake and go ouch.

Because the barrel/gas system is using the hand guard end to latch onto the receiver, they cannot make a hanguard any longer. They will need to do a funky add on like SCAR but that will definitely render the QD barrel useless. So IAR and DMR configurations will suck because there is little estate to mount bipod. The quick barrel release button on the left side potentially interferse with switches and wire setup, and that actually makes a hanguard extension even harder to work.

And where is the Grenada launcher? Launcher cannot just mount on pica tinny rail. It needs a "stopper" like CC IUR or a latching point like the HK416 at the gas block.

You know what? You are very correct. Like I said they already have a homemade german ar. One that has been proven to arguably be the top dog of the new assault rifles so much so that pretty much every tier one units(including their own) along with a few well funded armies adopted it. Why not just pick that?

I wonder if cost is the reason they are going this route.
 
This trial is an eye wash and a poke to the eyes of HK. No country in Europe has ever adopted a weapon from the outside if they have their own manufacturer.

Rheinmetall makes a lot of go great weapons, but small arms is not one of them. Styer hasn't come up with anything since the late 80's with the ACR and AUG sale is non-existing for years aside from the civilian market . Both of them are out of touch with assault rifle design.

They didn't till now. I believe france adopted the hk416.
And iirc Rheinmetall is a german company.


And I would argue the aug is still the bullpup to have despite newer offerings from iwi and fn herstal. I'm not even gonna bother mentioning the famas or sa80.

And yes rheinmetalls specialty is the big stuff. But with the resources they have along with supplier connections they have they can bring some top notch materials at a good price. Steyr. Well seeing that aug is still going strong is a testament to the designs merits.

And cost may be a very real reason for going this route.

Not to mention is it possible that the austrian military is looking to dump the aug and this might be the replacement for them as well?

Why, what did hk do?
 
It is also unnecessarily heavy for a 16" carbine. The bare rifle weighs 9.3 lbs loaded, so it should be a bit over 8 lbs empty. Minimizing the weight of the rifle should be more of a priority, considering all the different accessories like optic, night vision, light, IR, etc. that are commonly fitted to military rifles in this day and age.
 
Gee, another piston AR that weighs 5 lbs more than it needs to. Just what Herr Docktor ordered.

I wonder of the AUG order is for the Saudis, to replace the ones they dumped into Syria and Libya? There are a good number of those guns floating around Lebanon right now - seems some of the groups they were given to sold them on the black market and used the cash to buy AK's and ammo.
