Christensen Arms MPR Rimfire 22LR 20″ Tungsten | MFG# 801-12026-02

The Christensen Arms MPR Rimfire is a feature-rich bolt-action rimfire platform built around a carbon fiber tension barrel and a lightweight aluminum chassis. This 20-inch threaded model folds for compact transport and uses carbon-fiber components to keep weight down while maintaining rigidity. For optic pairing under $1,000, a Vortex Viper PST 2.5-10×44 provides versatile magnification and reliable performance on a precision rimfire chassis.

Well-suited for small-game hunting and rimfire precision competition, the MPR Rimfire balances packability with a user-adjustable chassis and a 0-MOA optic rail for accurate sighting. It accepts Ruger-compatible BX-1 magazines and features an adjustable FFT carbon-fiber cheek piece and adjustable length of pull for repeatable ergonomics.
