CHRIS MPR RIMFIRE 22WMR

The Christensen Arms MPR Rimfire in 22 WMR is a modern precision rifle built on a chassis platform that combines serious accuracy with packable portability. If you're tired of traditional rimfire rifles that feel like compromise platforms, this is a different breed entirely—it scales down the precision rifle features serious long-range and competition shooters expect, but engineered specifically for 22 WMR ballistics and the demands of small-game hunting, rimfire competitions, and extended-range plinking.

The foundation is a Christensen Arms precision-machined aluminum receiver paired with a TriggerTech trigger (Remington 700 compatible) that delivers predictable, clean breaks. The barrel is where the MPR Rimfire gets its accuracy pedigree: a Christensen carbon fiber tension barrel, precision lapped and button rifled with a match chamber and 1/2×28 threaded muzzle ready for suppressors or other muzzle devices. That carbon fiber construction keeps weight down without sacrificing rigidity—critical in a rifle designed to fold into your pack.

The chassis is a 7075 aluminum billet design with your choice of a 10.5" or 14" FFT carbon fiber handguard featuring M-LOK slots. The stock folds with a locking hinge and Magnelock technology, and the adjustable length of pull (12.5–14.5") means it fits different shooters and works over heavier outerwear in the field. An adjustable FFT carbon fiber cheek piece keeps your sight picture consistent, and six QD flush-cup mounts let you rig accessories without permanent hardware. The 0-MOA optic rail accepts standard mounts, and an AR-compatible grip feels familiar in your hand.

It ships with a Ruger BX-1 magazine, and the V-block bedding ensures consistent performance. Whether you're working steel at distance, running a rimfire match, or pursuing foxes and coyotes, the MPR Rimfire folds down small enough to pack without feeling like a toy when you shoulder it.
