Christensen Arms MPR Rimfire .22LR 18" Black/Tan Rifle - Model 8011202301

The Christensen Arms MPR Rimfire is a modern precision .22LR rifle built on a rigid aluminum chassis platform that brings competition-grade engineering to small-game hunting, range shooting, and rimfire competition. If you've been shooting traditional rimfire rifles and wondering what the next level looks like, this 18-inch platform bridges the gap between casual plinking and serious accuracy. The MPR combines a carbon-fiber tension barrel with a precision-machined aluminum receiver, delivering consistent performance in a lightweight, packable format that doesn't sacrifice rigidity or control.

What makes the MPR Rimfire stand out is its thoughtful balance of function and weight. The 7075-aluminum billet chassis gives you a solid foundation, while the FFT carbon-fiber handguard keeps things light without compromising stiffness. The folding stock with MagLock technology and adjustable length of pull (12.5–14.5 inches) means the rifle adapts to your setup rather than the other way around. Whether you're breaking down the rifle for a pack-in hunt, setting up at the bench, or running a timed stage, the compact footprint doesn't come at the cost of ergonomics or stability.

The trigger is a TriggerTech unit tuned for the Remington 700 platform—predictable, crisp, and reliable. The barrel wears a standard 1/2x28 threaded muzzle, so you can add a suppressor or muzzle device to suit your shooting style. Six QD mounts let you anchor accessories where you need them, and the adjustable FFT carbon-fiber cheek riser keeps your head in the same position shot after shot. This is a rimfire rifle built for shooters who care about consistency and don't mind investing in tools that reward precision.
