Christensen Arms MPR Rimfire | .17 HMR | 16″ | 801-12028-00

The Christensen Arms MPR Rimfire is a precision-oriented bolt-action rimfire platform built around a carbon fiber tension barrel and a lightweight billet aluminum chassis. This configuration emphasizes accuracy in a packable, folding design and includes adjustable cheek and length-of-pull features for a customized fit. A mid-range variable optic such as the Vortex Viper HS-T 4-16×44 (commonly available for under $1,000) pairs well with this rifle for both target work and extended-range rimfire applications. Common uses include small-game hunting and rimfire precision/practice shooting.
