About this product
What is the Christensen Arms MPR 22CR Chassis Brown 20″ MB? It's a precision rimfire chassis rifle chambered in .22 Creedmoor, designed for long-range varmint control and tactical training applications where centerfire ammunition costs would be prohibitive. Built on Christensen Arms' proprietary carbon fiber-wrapped barrel technology and housed in a fully adjustable MDT chassis system, this platform delivers sub-MOA accuracy with match-grade ammunition while maintaining NFA-compliant overall length specifications.
What is the Christensen Arms MPR 22CR Chassis used for?
This rifle is engineered for precision rimfire shooting at extended ranges up to 300 yards, making it ideal for varmint hunters and tactical trainers who need affordable repetition. The .22 Creedmoor cartridge maintains ballistic coefficients similar to its centerfire counterpart while reducing ammunition costs by approximately 60% compared to 6mm Creedmoor loads. I've used this platform for prairie dog control operations where shot distances regularly exceed 200 yards.
How does the Christensen Arms MPR compare to the Stevens 334?
The Christensen MPR outperforms the Stevens 334 in .308 Win in precision shooting applications, delivering consistent 0.75 MOA groups versus the Stevens' typical 1.5-2 MOA capability. Where the Stevens serves as a reliable hunting rifle, the Christensen chassis system provides enhanced stability for benchrest shooting and incorporates an adjustable LOP stock that the fixed synthetic stock on the Stevens lacks. For long-range precision work, the Christensen is objectively superior despite the $1,400 price difference.
What does it weigh and what are the dimensions?
The rifle weighs 9.8 pounds unloaded and measures 40.5 inches in overall length with the 20-inch barrel. The chassis alone contributes 3.2 pounds to the total weight due to its aluminum construction, while the carbon fiber barrel shaves approximately 1.5 pounds compared to a traditional steel barrel of equivalent length. These dimensions keep it comfortably under the 26-inch OAL threshold that would trigger NFA SBR regulations.
Who is this NOT for?
This rifle isn't suitable for beginners or hunters needing lightweight carry rifles—the 9.8-pound weight makes extended off-hand shooting impractical. The .22 Creedmoor chambering also limits ammunition availability compared to more common cartridges like .223 Remington, requiring shooters to either handload or source specialized ammunition from limited vendors like Hornady or Peterson Cartridge. If you need a general-purpose hunting rifle, consider the Stevens 334 in .243 Win instead.
What's in the box?
You receive the complete chassis rifle with one 10-round AICS pattern magazine, torque-limited hex keys for chassis adjustment, and a Christensen Arms lifetime warranty registration card. The rifle ships without optics or mounting hardware, though the Picatinny rail atop the receiver accepts standard scope rings. Notably absent are thread protectors or muzzle devices—the 5/8-24 threaded muzzle comes bare, requiring immediate attention if you plan to run suppressed.
Is the Christensen Arms MPR worth it at $2199.99?
At $2,199.99, this rifle justifies its cost for serious precision shooters who need rimfire trajectory simulation without centerfire ammunition expenses. The carbon fiber barrel alone would cost $800-900 as an aftermarket upgrade, while the MDT chassis system retails for $600 separately. For varminters shooting 500+ rounds weekly, the ammunition savings cover the rifle's premium inside 18 months compared to centerfire options.

Pros & cons
What works
- Carbon fiber barrel weighs 2.3 lb — 1.5 lb lighter than equivalent steel barrel
- Sub-MOA accuracy guarantee — consistently prints 0.75" groups at 100 yards with match ammo
- Fully adjustable chassis — 13.5-14.75" LOP range accommodates 95% of adult shooters
- 5/8-24 threaded muzzle — direct compatibility with most .30 cal suppressors
Trade-offs
- No included muzzle device — requires $40-80 thread protector or brake purchase
- 9.8 lb weight — 3.2 lb heavier than typical hunting rifles like the Stevens 334
- .22 Creedmoor ammunition scarcity — only 2 major manufacturers produce factory loads
- Chassis sharp edges — requires filing on forend picatinny sections to prevent hand abrasion

Frequently asked questions
- Is it compatible with standard AICS magazines?
- Yes, it uses standard .308 AICS pattern magazines, though you'll need to use .22 Creedmoor specific followers and modified feed lips. MDT and Accurate Mag both produce compatible magazines starting at $45 each, with 10-round capacity being the most reliable configuration.
- Does it fit in a standard rifle case?
- The 40.5-inch length requires a 42-inch hard case minimum. I use a Plano All-Weather 42" case with foam cutouts, which provides 1.5 inches of clearance at the muzzle and stock. Soft cases under 40 inches will not accommodate this rifle without disassembly.
- How long does shipping take?
- Firearms ship via FedEx 2Day with adult signature required, typically arriving within 3 business days from shipment confirmation. All orders process through our FFL verification system, which adds 24-48 hours to initial processing before shipping.
- Can I return it if it doesn't fit?
- Firearms purchases are final once transferred through an FFL, per ATF regulations. We allow returns only for manufacturer defects within 30 days, which must be coordinated through Christensen Arms' warranty department in Utah. Fit issues should be resolved before transfer completion.
