Christensen Arms MPR Rimfire .22LR 20" Black Nitride Rifle (8011202002)

The Christensen Arms MPR Rimfire .22LR rifle brings modern precision platform engineering to rimfire shooting. Built on a Remington 700-style action with dual extractors and dual opposing locking lugs, this 20-inch rifle delivers accuracy and modularity usually reserved for centerfire precision rigs. The carbon fiber tension barrel is precisely machined with a match chamber and button rifling for consistent performance downrange, while the 1/2 x 28 threaded muzzle opens the door to suppressors and muzzle devices. Whether you're shooting small-game, running steel plates, or just putting rounds downrange for fun, this is a rimfire platform that doesn't compromise on capability.

The heart of the MPR Rimfire is its 7075 billet aluminum chassis—the same premium material you'll find in modern AR-15 and precision centerfire builds. The included FFT carbon fiber handguard is offered in 10.5 or 14-inch lengths with M-LOK slots for mounting lights, bipods, or other accessories. A TriggerTech trigger (Remington 700 compatible) gives you clean, predictable breaks, while the folding stock with MagneLock technology and adjustable length of pull (12.5–14.5 inches) lets you dial in your fit. The V-block bedding keeps zero stable, and six QD flush-cup mounts let you run slings however you prefer. An adjustable FFT carbon fiber cheek riser helps dial in your sight picture, and the monopod Picatinny mount provides options for field shooting. At its core, this is a compact, packable platform that folds down for transport yet reaches out to impressive distances—a true all-arounder for rimfire enthusiasts.

Feeding is handled by a Ruger BX-1 magazine, and the 0-MOA optic rail gives you a clean foundation for mounting your glass. The receiver is precision-machined aluminum with an AR-compatible grip, making the platform familiar to shooters who know modern sporting rifles. The black nitride finish on the barrel delivers durability and corrosion resistance in a professional look.
