Christensen Arms MPR Rimfire .22 Magnum 18" Barrel Black/Tungsten Rifle - Model 8011202701

The Christensen Arms MPR Rimfire is a modern precision rifle built for shooters who refuse to compromise on accuracy or versatility. Chambered in .22 Magnum with an 18-inch carbon fiber tension barrel, this rifle delivers the kind of performance and packability you'd expect from a platform designed by engineers who understand both rimfire ballistics and practical field use. Whether you're zeroing in at the range, hunting small game, or running competition drills, the MPR Rimfire bridges the gap between a precision tool and a go-anywhere companion.

The chassis foundation starts with a precision-machined aluminum receiver featuring dual extractors and dual opposing locking lugs—the same lockup geometry that keeps centerfire platforms running tight shot after shot. The TriggerTech trigger (Remington 700-compatible) delivers the crisp, predictable break serious shooters demand, while the 0-MOA optic rail gives you a clean mounting surface for your glass. A threaded muzzle (1/2 x 28) opens up suppressor options if your local regs allow.

What sets the MPR Rimfire apart is its modular, packable design. The 7075 aluminum billet chassis accepts either a 10.5- or 14-inch FFT carbon fiber handguard (your choice) with M-LOK slots for mounting lights, slings, or tactical accessories. The folding stock with locking hinge and MageLock technology folds the rifle down small enough to slip into a pack—critical for backcountry hunters and overlanders who measure every ounce. Length of pull adjusts from 12.5 to 14.5 inches, and the adjustable FFT carbon fiber cheek riser lets you dial in your sight picture. Six QD flush-cup mounts plus a Picatinny monopod mount give you flexibility for how you configure the rifle.

The rifle ships with a Ruger BX-1 magazine and sits on V-block bedding for consistency. This is a rimfire that doesn't feel like a compromise—it's built like one of Christensen's centerfire rigs, scaled intelligently for .22 Magnum ballistics and the shooters who take their rimfire work seriously.

Frequently Asked Questions

Can I fold the stock, and how compact does it get?

Yes. The stock folds via a locking hinge with MageLock technology. This design lets the rifle collapse into a more compact footprint for transport in packs or vehicles—a key feature for overlanders and backcountry hunters who need to keep overall length in check.

Is the length of pull adjustable?

Yes. LOP adjusts from 12.5 to 14.5 inches, so you can dial in a comfortable fit whether you're shooting in a light jacket or heavy winter gear. The adjustable FFT carbon fiber cheek riser also helps you find the right sight picture with your scope.

Can I use suppressors and other muzzle devices?

The barrel is threaded 1/2 x 28 (the standard for .22 rimfire), so yes—suppressors, flash hiders, and other muzzle devices that use this thread pattern will fit. Check your local and state laws before using a suppressor.

What magazine does it use?

The rifle ships with a Ruger BX-1 magazine and is compatible with that platform.

What handguard length does this come with?

The product record specifies this is the 18-inch barrel model with a Black/Tungsten finish, and the handguard options are 10.5 or 14 inches—both FFT carbon fiber with M-LOK. Confirm with Bosque Outdoors which version ships with your rifle.
