The StG M90, officially the Stormgevär Modell 90, is an Acrean 6.8x43mm select-fire rifle designed by the Stuhr Arsenal for the Acrean Armed Forces to meet requirements for a lighter primary weapon for special forces and reconnaissance troops. Entering service in 1990, the M90 was considered advanced for its time due to its use of primarily polymer construction and omission of primary iron sights in favour of the use of integrated optical sights. In addition, the rifle has become known for its light weight, reliability, ease of maintenance, and modularity. It has continuously upgraded since its adoption. The M90 was never pressed into service as Acrea's standard service rifle, with the StG M65 having already supplemented the M51 in service.
In addition to adoption by the Acrean Army, the M90 has seen widespread use among law enforcement agencies in Acrea and abroad.
