Ruger American Rimfire | 18″ Threaded | Black Synthetic | 8312

The Ruger American Rimfire presents a user‑adjustable platform built around a free‑floating, cold hammer‑forged 18″ barrel with a threaded muzzle and a modular synthetic stock. The rifle uses Ruger’s Power Bedding integral bedding block and a user‑adjustable Marksman trigger to support consistent shot placement and straightforward maintenance. The receiver is drilled and tapped with a 3/8″ rimfire base and includes an easy 10/22‑style magazine release for the detachable rotary magazine.
