Christensen Arms MPR Rimfire .22 WMR 16″ Desert Brown

The Christensen Arms MPR Rimfire .22 WMR 16″ Desert Brown is a chassis-style bolt-action rifle built for precision rimfire shooting that you can actually pack into the backcountry. Chambered in .22 Winchester Magnum, this rifle pairs a 16-inch carbon fiber tension barrel with a threaded muzzle for suppressor or brake compatibility. The 7075 aluminum billet chassis features a folding MagneLock stock, an adjustable FFT carbon-fiber cheekpiece, and a TriggerTech trigger that accepts Remington 700-style systems. A 0-MOA Picatinny optic rail and M-LOK FFT handguard let you mount modern scopes and accessories. Per Christensen Arms specs, the total weight is just 5.2 pounds, making this one of the lightest precision rimfire rifles on the market. Last updated: April 2026.

Key Features

• Carbon Fiber Tension Barrel: The 16-inch carbon fiber tension barrel reduces weight while maintaining stiffness. Why it matters: Barrel harmonics stay consistent shot-to-shot, which translates to sub-MOA groups at 100 yards with match-grade .22 WMR ammo.
• Folding MagneLock Stock: The stock folds via a magnetic latch system, collapsing the overall length to just 26 inches. Why it matters: You can stow this rifle in a daypack or behind a truck seat without losing zero—critical for varmint hunters and precision rimfire shooters who move between positions.
• TriggerTech Trigger: Factory-installed TriggerTech trigger with a crisp, adjustable break (2.5–5 lbs). Why it matters: Consistent trigger pull eliminates shooter-induced error; this system is compatible with aftermarket Remington 700 triggers for further tuning.
• 0-MOA Picatinny Optic Rail: A full-length 0-MOA rail is machined into the receiver. Why it matters: No need for aftermarket bases—just mount your scope directly and dial in elevation for 200-yard rimfire shots.
• M-LOK FFT Handguard: The free-floating handguard uses M-LOK slots at 3, 6, and 9 o’clock. Why it matters: Attach a bipod, barricade stop, or laser without adding weight or affecting barrel harmonics.

Who It’s For

This rifle is for the precision rimfire shooter who demands sub-MOA accuracy from a package under 6 pounds. If you shoot NRL22, hunt prairie dogs at 150+ yards, or want a trainer that mirrors your centerfire chassis setup, the MPR Rimfire delivers. It also suits backpack hunters who need a lightweight .22 WMR for small game without sacrificing accuracy.

Pros and Cons

Pros

• Ultralight at 5.2 lbs with a folding stock
• Threaded muzzle (1/2×28) for suppressor use
• Remington 700 trigger compatibility for upgrades
• Desert Brown Cerakote resists corrosion in wet conditions

Cons

• 0-MOA rail limits long-range elevation adjustment with some scopes; you may need a 20-MOA base for 200+ yard rimfire shooting
• Magazine capacity is 10 rounds—adequate for hunting but slower in competition stages requiring rapid reloads
