The Christensen Arms MPR Rimfire is a precision .22 Magnum rifle built for shooters who refuse to compromise on accuracy, modularity, or portability. This modern precision rimfire combines a carbon fiber tension barrel with a billet aluminum chassis platform, delivering sub-MOA capability in a rifle light enough to pack into the field or fold down for transport. Whether you're zeroing in on small game, running a rimfire competition, or putting rounds downrange at distance, the MPR Rimfire punches above its weight class.
The heart of the MPR is Christensen Arms' proprietary carbon fiber tension barrel paired with a match chamber and precision lapping—the same quality engineering that built the company's reputation for long-range hunting rifles. The receiver is a precision-machined aluminum design fitted with dual extractors and dual opposing locking lugs for reliable feeding and extraction. A TriggerTech trigger (Remington 700–compatible) delivers a clean break right out of the box, and the 0-MOA optic rail is ready for your favorite scope or red dot. All of this rides in a 7075 billet aluminum chassis with genuine adjustability: your cheek piece and length of pull both dial in to fit your body, and the folding stock locks solid when deployed or collapses for transport.
The 18-inch barrel wears a black nitride finish and features 1/2 x 28 threading, ready for a suppressor or muzzle device. The FFT carbon fiber handguard runs full length with M-LOK slots for mounting lights, bipods, or other gear. Six QD flush-cup mounts and a monopod Picatinny mount give you attachment points wherever you need them. It ships ready to shoot with a Ruger BX-1 magazine and accepts standard .22 Magnum ammunition. The MPR Rimfire is a do-it-all platform: compact enough to backpack, precise enough to compete, and tough enough for any outdoor mission.
