Christensen Arms MPR Rimfire 18″ Threaded Barrel, Tungsten
Pros & cons
What works

- Folds to 26 inches — 40% shorter than fixed-stock competitors for transport
- TriggerTech-compatible trigger allows pulls down to 1.5 lbs for precision work
Trade-offs
- No included optics or mounts — adds $300+ for a proper scope setup
- Tungsten Cerakote shows handling marks more than matte finishes
- Requires proprietary BX-1 mags — limits compatibility with common 10/22 accessories

About this product
What is the Christensen Arms MPR Rimfire 18″ Threaded Barrel, Tungsten? The Christensen Arms MPR Rimfire is a precision bolt-action rimfire chassis rifle featuring an 18-inch carbon fiber-wrapped match-grade barrel with 1/2×28 threading, designed for portability and sub-MOA accuracy. It combines a billet aluminum receiver with a folding MagneLock stock and TriggerTech-compatible trigger in a tungsten Cerakote finish. This platform accepts Ruger BX-1 magazines and includes M-LOK compatible handguards for tactical versatility.
What is the Christensen Arms MPR Rimfire used for?
The MPR Rimfire excels in rimfire competitions, small-game hunting, and precision range training where compactness and repeatable accuracy matter. Its 18-inch threaded barrel and 8.6-pound weight make it stable for off-hand shooting while remaining packable with the folding stock deployed. The sub-MOA guarantee at 50 yards ensures consistent performance whether you're punching paper or hunting squirrel.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334 Rifle?
The MPR Rimfire outperforms the Stevens 334 in accuracy and modularity but sacrifices centerfire capability. Where the Stevens 334 in .308 Win offers hunting power at 20 inches barrel length, the Christensen provides superior trigger tuning, carbon fiber barrel tension, and chassis-style ergonomics for precision rimfire work. The MPR is better for competition and suppressor use; the Stevens 334 is better for big game.
What does it weigh and what are the dimensions?
The rifle weighs 8.6 pounds and measures 35.5 inches overall length with the stock extended, folding to 26 inches for transport. The 18-inch barrel contributes to balance without adding excessive weight, and the carbon fiber handguard keeps front-end mass minimal. These dimensions make it one of the more compact precision chassis systems available, though still substantial enough for stable benchery.
Who is this NOT for?
This rifle isn't for budget-conscious shooters or those needing centerfire power for large game. At $1925.99, it demands investment compared to budget options like the Stevens 334. The rimfire chambering limits effective range to about 150 yards, and the chassis design may feel overly tactical for traditional hunters preferring walnut stocks.
What's in the box?
You get the complete rifle with one 9-round Ruger BX-1 magazine, ensuring immediate function out of the box. Christensen Arms includes all necessary QD mounts for slings or bipods and the MagneLock stock adjustment tools. The package lacks optics or a case, so factor in another $300–500 for a quality scope mount and rings.
Is the Christensen Arms MPR Rimfire worth it at $1925.99?
Yes, if you demand sub-MOA accuracy, suppressor readiness, and folding compactness in a rimfire platform. The carbon fiber barrel and TriggerTech trigger justify the cost for serious competitors or trainers mimicking centerfire setups. For plinking or casual use, a Stevens 334 at half the price makes more sense, but the MPR delivers where precision matters.

Frequently asked questions
- Is it compatible with standard Ruger 10/22 magazines?
- No, it uses Ruger BX-1 magazines specifically, which hold 9 rounds and are slightly different from the classic 10/22 rotary mags. You'll need to purchase BX-1 or compatible aftermarket versions for reliable feeding.
- Does it fit in a standard rifle case when folded?
- Yes, at 26 inches folded length, it fits most 28-inch tactical cases like those from Plano or Pelican. Measure your case interior to confirm, but it's designed for compact storage and transport.
- How long does shipping take?
- Shipping typically takes 3–7 business days within the continental US via FedEx or UPS Ground. Expedited options are available at checkout for an additional fee, cutting transit to 2 days.
- Can I return it if I don't like the trigger feel?
- Returns are accepted within 30 days if the rifle is unfired and in original packaging, but custom triggers like the TriggerTech may require break-in. Contact our support team for specific cases—once fired, it's considered used and ineligible for return.
