Christensen Arms MPR Rimfire .22LR 18" Black/Tungsten 8011202601

The Christensen Arms MPR Rimfire is a .22LR precision rifle that brings modern chassis-platform engineering to rimfire shooting. Built on a Remington 700-style action with a precision-machined aluminum receiver, this 18-inch carbon fiber tension barrel rifle delivers the accuracy and adjustability you'd expect from a dedicated precision platform—scaled down for .22LR hunting, competition, and range work. It's designed for shooters who want serious performance from a rimfire without compromise, whether you're hunting small game, competing in precision rimfire events, or pushing distances that most stock .22s can't reliably reach.

The heart of the MPR Rimfire is its Christensen Arms carbon fiber tension barrel, precision lapped and button rifled with a match chamber and 1/2 x 28 threaded muzzle. That combination of lightweight carbon fiber construction and precision manufacturing means less barrel whip, tighter groups, and the kind of accuracy that makes serious rimfire shooting worthwhile. The 7075 aluminum billet chassis provides a rigid platform, while the FFT carbon fiber handguard with M-LOK slots gives you mounting flexibility without adding weight.

What sets the MPR Rimfire apart is its modularity and packability. The folding stock with Magnelock technology locks down securely when deployed but collapses to fit into a pack or bag—ideal for backcountry small-game hunting or field competitions. The adjustable FFT carbon fiber cheek riser and length-of-pull adjustment (12.5–14.5 inches) let you dial in a custom fit. Six QD flush-cup mounts and the monopod Picatinny mount ready receiver give you options for slings, supports, and accessories. The TriggerTech trigger (Rem 700 compatible) breaks clean, and the rifle ships with a Ruger BX-1 magazine, so you can start shooting right away.

This is a rimfire platform for shooters who treat .22LR as seriously as centerfire—hunters who rely on precision, competitors who demand consistency, and anyone who wants to squeeze every bit of performance and capability out of a lightweight, packable rifle.
