Christensen Arms MPR Rimfire .17 HMR 20" Black Nitride Bolt-Action Rifle (8011202202)

The Christensen Arms MPR Rimfire is a .17 HMR bolt-action rifle that brings modern precision-rifle engineering to the rimfire category. Built on a billet aluminum chassis with a carbon fiber tension barrel, this 20-inch rifle delivers the accuracy and adjustability of a high-end competition platform in a surprisingly packable, lightweight package. Whether you're hunting small game, running steel at the range, or just enjoying accurate shooting, the MPR Rimfire punches well above what you'd expect from a rimfire.

The heart of the system is Christensen Arms' proprietary carbon fiber tension barrel, precisely lapped and button-rifled with match-chamber accuracy. The receiver is a precision-machined aluminum unit featuring dual extractors, dual opposing locking lugs, and a factory TriggerTech trigger tuned for Rem 700 compatibility—meaning a clean, predictable break every shot. A 0-MOA optic rail is integral to the design, so you're set for mounting your glass without workarounds.

The chassis itself is where this rifle shines. The 7075 aluminum billet frame accepts either a 10.5 or 14-inch FFT carbon fiber handguard with M-LOK slots for lights, braces, or other accessories. The folding stock uses a locking hinge and MagLock technology, letting you pack this rifle flat without sacrificing rigidity. The adjustable carbon fiber cheek riser and length-of-pull range (12.5–14.5 inches) accommodate different optics and shooter builds. Six QD mounts round out the modularity. The barrel threads accept standard 1/2×28 suppressors, and a Ruger BX-1 magazine feeds the action—reliable, field-proven, and affordable.

This is a purpose-built rimfire for shooters who demand precision, adjustability, and the ability to dial in their setup. It's light enough to carry all day, rigid enough to keep groups tight, and thoughtfully engineered to grow with your skills and mission.

Specifications

Frequently Asked Questions

Can I suppress this .17 HMR rifle?

Yes. The barrel is threaded 1/2×28, which is the standard suppressor thread pitch for .17 HMR. You'll need a suppressor rated for that caliber, and the design is compatible.

What magazine does the MPR Rimfire take?

The rifle is compatible with Ruger BX-1 magazines, which are widely available, affordable, and known for reliability. This is a practical, field-tested choice for rimfire shooters.

Is the stock really foldable, and will it stay rigid when deployed?

Yes. The folding stock uses a locking hinge with MagLock technology, which locks the stock securely in place when deployed. This lets you pack the rifle compactly while maintaining the rigidity you need for accuracy shooting.

Can I adjust the cheek riser and length of pull to fit my build?

Yes to both. The FFT carbon fiber cheek riser is adjustable to dial in your eye relief with different optics. The stock length of pull adjusts from 12.5 to 14.5 inches, so you can tailor the fit to your torso length and how you run a sling or chassis.

What kind of accuracy can I expect from a rimfire?

The MPR Rimfire is built to precision-rifle standards—carbon fiber tension barrel, match chamber, button rifling, and precision-lapped bore. .17 HMR inherently shoots tight groups at moderate ranges, and this platform maximizes that potential. Exact performance depends on ammunition, but the engineering here is uncompromising.

What optic rail does this rifle use?

The receiver has an integral 0-MOA optic rail. This is Rem 700-style compatible and comes ready to accept standard scope rings and mounts.
