CHRIS MPR Rimfire 22WMR Precision Rifle - High Accuracy .22 Magnum Firearm

The Christensen Arms MPR Rimfire is a modern precision rifle built for shooters who refuse to compromise on accuracy or versatility. Chambered in .22 WMR, this platform combines a carbon fiber tension barrel with a billet aluminum chassis to deliver the kind of precision you'd expect from a full-size tactical rifle—but scaled perfectly for rimfire shooting, small-game hunting, competition, and range work. The carbon fiber handguard and folding stock make it genuinely packable without sacrificing the modularity and adjustability serious shooters demand.

Built on a Christensen Arms precision-machined aluminum receiver with dual extractors and dual opposing locking lugs, the MPR Rimfire feeds reliability through a Ruger BX-1 magazine and breaks cleanly with a TriggerTech trigger (Remington 700 compatible). The 7075-T73 aluminum billet chassis houses a v-block bedded action and generous M-LOK mounting options across the FFT carbon fiber handguard—10.5" or 14" depending on your preference—letting you set up glass, lights, and accessories exactly how you want them. Six QD flush-cup mounts round out the accessory ecosystem.

What sets the MPR Rimfire apart is its focus on shootability without the bulk. The folding stock uses a locking hinge and Magnelock technology to collapse down for pack-and-hike duty, while the adjustable FFT carbon fiber cheek riser, adjustable length of pull (12.5–14.5"), and AR-compatible grip let you dial in your position. The 0-MOA optic rail is precision-machined, and the barrel is threaded 1/2 × 28 (standard) in case you want to run a suppressor. Whether you're stretching your skills at distance, dropping varmints, or competing in a rimfire match, the MPR Rimfire is engineered to perform in a lightweight, portable package.
