Christensen Arms MPR Rimfire .22 WMR 18″ Black

Description

The Christensen Arms MPR Rimfire .22 WMR 18″ Black is a chassis-style rimfire rifle built around a carbon-fiber tension barrel and a lightweight billet aluminum receiver. It pairs a Remington 700-style TriggerTech trigger with an FFT carbon-fiber handguard, adjustable carbon cheek piece, and a folding stock for a compact, packable package. This platform is intended for precision rimfire shooting, small-game hunting, and target work where light weight and accuracy matter. The rifle ships with a Ruger BX-1 magazine and a threaded muzzle for accessory use. Per Christensen Arms specs, the carbon-fiber barrel is tensioned to reduce harmonics and maintain consistent accuracy shot after shot.

Key Features

• Carbon-Fiber Tension Barrel – The 18″ barrel is wrapped in carbon fiber and tensioned to minimize barrel whip. This keeps your point of impact consistent even during rapid strings, critical for small-bore precision.
• TriggerTech Trigger – A Remington 700-style TriggerTech trigger gives you a crisp, adjustable pull with zero creep. You get a clean break every time, which translates to tighter groups at 50 and 100 yards.
• Adjustable Carbon Cheek Piece & Folding Stock – The cheek piece adjusts for height and the stock folds to the right, making the rifle compact enough for a backpack. This is a game-day advantage when you need to move fast between stages or hike into a hunt.
• Threaded Muzzle (1/2×28) – The muzzle is threaded for suppressors or compensators. Running a can reduces report and recoil, helping you stay on target for follow-up shots.

Who It’s For

This rifle is built for competition shooters who demand rimfire accuracy in a lightweight package. If you shoot NRL22, PRS Rimfire, or small-game matches where every ounce matters, the MPR Rimfire is your edge. It’s also ideal for hunters who want a packable .22 WMR that doesn’t sacrifice precision for portability. If you’re a reloader or tinkerer who values aftermarket support, the Remington 700 footprint means you can swap stocks, triggers, and chassis components easily.

Pros & Cons

Pros: Sub-6-pound weight, carbon-fiber barrel for reduced harmonics, TriggerTech trigger for a clean break, folding stock for compact carry, threaded muzzle for accessories.

Cons: The carbon-fiber handguard can feel warm after extended strings, and the folding stock’s cheek piece may need a shim for shooters with high comb preferences. Per Christensen Arms specs, the barrel is not user-serviceable for tension adjustment.
