About this product
The Christensen Arms MPR Rimfire 17HMR 20″ Black is a precision rimfire chassis rifle that pairs a carbon fiber tension barrel with a folding stock for maximum portability without sacrificing accuracy. Built on a lightweight billet aluminum chassis with full adjustability, this rifle represents the intersection of high-end materials and practical field design. Christensen Arms backs this platform with a 50-yard sub-MOA guarantee, making it one of the few rimfire rifles sold with a factory accuracy warranty.
What is the Christensen Arms MPR Rimfire used for?
This rifle is designed for precision rimfire applications where portability and sub-MOA accuracy matter equally. The 20-inch carbon fiber barrel and chassis system make it ideal for varmint control at distances up to 200 yards, long-range rimfire competitions, and backpack hunting trips where every ounce counts. The folding stock reduces the overall length to just 28 inches for transport, then locks up solid for stable shooting.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334?
The MPR Rimfire outperforms the Stevens 334 in precision engineering and material quality but costs significantly more. Where the Stevens uses standard steel barrels and basic synthetic stocks, the Christensen Arms features a carbon fiber tension barrel that weighs 1.8 pounds less while maintaining better heat dissipation. The MPR's chassis system provides superior modularity with M-LOK attachment points versus the Stevens' fixed design.
What does it weigh and what are the dimensions?
The rifle weighs 5.9 pounds unloaded and measures 40.5 inches overall with the stock extended. The carbon fiber barrel accounts for just 1.4 pounds of that total weight, while the folding mechanism reduces the packed length to 28 inches for transport. The handguard provides 12 inches of continuous M-LOK real estate for accessories, and the adjustable cheekpiece offers 1.5 inches of vertical travel.
Who is this NOT for?
This rifle isn't for budget-conscious shooters or those needing a simple plinking gun. At $1,925.99, it costs nearly four times what you'd pay for a basic rimfire rifle like the Stevens 334 in .243 Win. The precision-focused design also means it's overkill for casual range use where minute-of-soda-can accuracy suffices. If you're not planning to utilize the sub-MOA capability or need extreme portability, save your money.
What's in the box?
You get the complete rifle, one Ruger BX-1 magazine, and the factory warranty documentation. The rifle ships with a 0-MOA Picatinny rail pre-installed but without optics, requiring an additional $200-800 investment for proper glass. The threaded barrel comes ready for suppressors but lacks thread protection, so plan on purchasing a cap or muzzle device separately.
Is the Christensen Arms MPR Rimfire worth it at $1,925.99?
Yes, if you need laboratory-grade accuracy in a packable platform and understand the premium materials justify the cost. The carbon fiber barrel alone adds several hundred dollars to manufacturing costs compared to standard steel barrels, while the billet aluminum chassis represents another significant investment. For varmint professionals or competitive shooters who'll use the full capability, the price delivers value; for occasional use, it's excessive.

Frequently asked questions
- Is it compatible with standard Ruger 10/22 magazines?
- No, this rifle uses Ruger BX-1 magazines specifically designed for the 17HMR cartridge. Standard 10/22 .22LR magazines will not function due to different cartridge dimensions and magazine well specifications. The action is built around the 17HMR platform, requiring magazines with different feed lip geometry.
- Does the threaded barrel accept standard 1/2x28 muzzle devices?
- Yes, the 1/2x28 thread pattern accommodates most common rimfire suppressors and muzzle devices without adapters. The threads are cut to SAE specifications, compatible with popular brands like SilencerCo and Dead Air. Thread depth measures 0.400 inches, providing sufficient engagement for secure attachment.
- How long does shipping take for firearms?
- Firearms typically ship within 3 business days after FFL verification, with transit times of 2-5 days depending on your location. All shipments require signature confirmation and direct delivery to your chosen licensed FFL holder. We use FedEx Firearms Program shipping for all firearm transactions.
- Can I return it if it doesn't meet accuracy expectations?
- Christensen Arms offers a 50-yard sub-MOA guarantee, but returns must go through their warranty process rather than standard retail returns. You'll need to provide 5-shot group documentation measuring under 1 inch at 50 yards. If the rifle fails this test, Christensen will repair or replace it under their lifetime warranty.
