Steyr ACR: A Polymer Flechette-Firing Bullpup From the 90s

The FN FS2000, nicknamed the 'Combat Tuna,' is a bullpup rifle known for its extensive use of polymers and an innovative forward case ejection system designed for ambidextrous operation. While adopted by some militaries like Slovenia, it faced challenges in the US market and military sales due to its quirky design and difficult malfunction clearing. The integrated optic is considered functionally subpar, with flat-top versions being more practical. The rifle's design aims for ambidexterity, but the charging handle remains on the left side, posing an awkwardness for left-handed shooters. Its unique case ejection system, while preventing brass from hitting left-handed shooters, contributes to the difficulty in clearing malfunctions, often requiring full field stripping.
