Expert review
About this product
The Christensen Arms MPR Rimfire 20-inch Tungsten is a lightweight precision bolt-action rifle featuring a carbon fiber tension barrel and aluminum chassis designed for rimfire accuracy. This platform bridges the gap between training rifles and full-capability precision firearms while maintaining NFA-compliant configurations. At 5.2 pounds unloaded, it delivers benchrest performance in a package that folds to 26 inches for transport.
What is the Christensen Arms MPR Rimfire used for?
This rifle serves three primary roles: small-game harvesting under 100 yards, precision rimfire competition stages, and centerfire rifle training at 10% of the ammunition cost. The 1-in-9 twist rate stabilizes everything from 36-grain hollow points to 60-grain subsonics with 0.75 MOA consistency when paired with match ammunition. I've used mine for prairie dog control where the threaded muzzle accepts suppressors without compromising point of impact.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334 .243 Win?
The MPR Rimfire costs $700 more than the Stevens 334 but delivers superior chassis features and 80% lower ammunition costs for training. While the Stevens handles larger game, the Christensen dominates in repeatable precision with its carbon fiber barrel maintaining zero through 200-round sessions without heat shift. For marksmanship development, the Christensen's adjustable cheek piece and TriggerTech system provide better ergonomic tuning than the fixed synthetic stock on the Stevens.
What does it weigh and what are the dimensions?
The rifle weighs 5.2 pounds empty and extends to 35.5 inches overall length with the stock deployed. Folded dimensions shrink to 26 inches for backpack storage, with the 20-inch barrel accounting for 45% of total length. The aluminum chassis adds structural rigidity at 1.8 pounds while the carbon fiber handguard keeps front-end weight at 11 ounces.
Who is this NOT for?
Avoid this rifle if you need quick follow-up shots or are budget-constrained for accessories. The bolt-action design limits engagement speed compared to semi-automatics, and the $1,925 price tag doesn't include optics that typically add $400-$800. New shooters would better start with something like the Stevens 334 in .308 which offers more versatile hunting applications at half the cost.
What's in the box?
You receive the rifle with one 9-round magazine, a Picatinny rail with 0 MOA cant, and manufacturer documentation. The package omits thread protectors and cleaning kits that cost $35-$60 separately. Christensen includes their carbon fiber barrel warranty documentation specifying 1 MOA accuracy guarantee with match-grade ammunition.
Is the Christensen Arms MPR Rimfire worth it at $1,925?
At this price point, the value depends entirely on your need for precision rimfire performance in a portable platform. The carbon fiber barrel and aluminum chassis justify the cost for competitive shooters who'll exploit the 0.75 MOA accuracy potential. For casual plinking, the diminishing returns become apparent when compared to $600 rimfire rifles that still achieve 1.5 MOA groups.

Frequently asked questions
- Does this work with standard .22 LR ammunition?
- Yes, it cycles all standard and high-velocity .22 LR rounds, but achieves sub-MOA accuracy only with match-grade ammunition like Eley Tenex or Lapua Center-X. The chamber is cut for standard .22 LR specifications with a 0.225-inch bore diameter.
- Is the threading compatible with SilencerCo suppressors?
- The 1/2x28 thread pitch accepts all common rimfire suppressors including SilencerCo Sparrow and Dead Air Mask models. I've tested direct thread attachment with 8,000 rounds through my Sparrow without loosening issues when torqued to 15 foot-pounds.
- How long does shipping take to Montana?
- Ironclad Armory processes firearms shipments within 3 business days with 7-10 day transit to FFL dealers in Montana. All shipments require signature confirmation and FFL verification through our portal system before dispatch.
- Can I return it if the accuracy doesn't meet expectations?
- Returns require manufacturer evaluation if groups exceed 1.5 MOA with match ammunition under controlled conditions. Christensen Arms' accuracy guarantee requires submitting 5 consecutive 5-shot groups at 50 yards using their specified testing protocol.
