Rheinmetall and Steyr Mannlicher have joined forces to manufacture and market the RS556 modular assault rifle (AR), in a German-Austrian cooperation project that 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.
The companies are offering the RS556 AR 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 AR System for the German Armed Forces (Bundeswehr), in which it intends 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.
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 (14.5in, 16in, 18in, and 20in); 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.
