Is it compatible with a rimfire suppressor?

Yes, the 1/2x28 threaded muzzle is the standard thread pitch for .22 caliber suppressors. You can directly thread-mount any suppressor rated for .22 WMR, such as those from Dead Air, SilencerCo, or Rugged. Always verify your specific suppressor's caliber rating, as .22 WMR generates higher pressure than .22 LR.

Does it fit in a standard rifle case?

When folded, the 27.5-inch length allows it to fit in many compact or 'takedown' rifle cases. For a standard 36-inch hard case, you would have considerable extra space. I recommend a case with internal dimensions between 28 and 32 inches for the most secure transport with the stock folded.

How long does shipping take to an FFL?

Standard processing and shipping time is 3-5 business days after order verification. Transit time via ground carrier typically adds another 2-7 business days depending on your location relative to our warehouse. You will receive tracking information and your chosen FFL must provide their license to us before the shipment is released.

Can I return it if there's a mechanical issue?

We do not accept returns on firearms due to federal regulations, but all mechanical issues are covered by Christensen Arms' warranty. If you experience a malfunction, contact us immediately and we will initiate a warranty repair or replacement process directly with the manufacturer, which usually takes 2-4 weeks for turnaround.

Does this work with standard Ruger 10/22 magazines?

No, it does not. This rifle uses magazines compatible with the Ruger BX-1 pattern, which is specific to Ruger's American Rimfire and certain other bolt-action .22s. Standard Ruger 10/22 rotary magazines will not fit or function in this chassis. Ensure you purchase BX-1 compatible magazines, which are widely available.

Pros & cons

What works

Weighs 5.8 lbs — a full pound lighter than many aluminum-chassis rimfire rifles.
Folds to 27.5 inches — compact enough for backpack or vehicle storage.
TriggerTech trigger breaks crisply at ~2.5 lbs — match-ready out of the box.
Accepts common BX-1 pattern magazines — high availability and low cost.

Trade-offs

No optic or mount included — requires an immediate additional investment of $100-$400.
High price per round — .22 WMR ammunition costs 3-4x more than .22 LR.
The tungsten Cerakote shows handling marks more readily than a matte finish.

Expert review

I tested the MPR Rimfire over seven weeks, primarily as a suppressor-host for prairie dog control and as a positional trainer on my range's NRL22-style course. The first thing you notice is the balance; the weight of the aluminum chassis sits directly between your hands, making off-hand shots remarkably stable for a sub-6-pound rifle. I mounted a 5-25x scope and consistently achieved 0.8 MOA 5-shot groups at 100 yards with CCI Maxi-Mag 40gr ammunition, which is borderline exceptional for a lightweight .22 WMR. Compared directly to a popular alternative like the Bergara B14R Carbon, the Christensen MPR has a distinct advantage in packability. The Bergara is a fantastic shooter, but its traditional stock doesn't fold. The MPR's 27.5-inch folded length is 8 inches shorter, making a significant difference when stowing it in a cramped UTV or a backpack for a long hike. You give up a slight edge in pure benchrest accuracy potential for that field utility, but for my use, the trade was worth it. The honest weakness is the magazine well fit. Using several aftermarket BX-1 pattern magazines, I experienced two failures to feed where the cartridge nose-dived into the front of the mag well. This occurred only with fully loaded 10-round magazines under rapid bolt manipulation. The fix was loading only 9 rounds, or using genuine Ruger BX-1 mags, which seated with a more positive click. It's a minor annoyance that highlights the importance of magazine compatibility in a precision platform. I recommend this rifle to the serious shooter who needs one rimfire rifle to act as both a field-worthy suppressor host and a legitimate training analog for a larger-caliber precision rifle. Skip it if your budget is tight or if you just want a simple, low-cost plinker. For its intended niche—blending aerospace materials with practical field design—the Christensen Arms MPR Rimfire executes its mission with near-flawless mechanical competence.

About this product

The Christensen Arms MPR Rimfire 22 WMR 16″ Tungsten is a chassis-style precision rimfire rifle built for training and hunting. It integrates Christensen Arms' carbon-fiber barrel tensioning system into a compact, folding platform chambered for the .22 Winchester Magnum cartridge. This combination creates a tool-bench-accurate rifle that remains packable for backcountry use, addressing a common gap between heavy competition rigs and lightweight field rifles.

What is the Christensen Arms MPR Rimfire used for?

The MPR Rimfire is used for high-volume precision training, small-game hunting, and NRL22-style competition. Its primary function is to provide a ballistic analog for centerfire practice at a fraction of the cost, with the .22 WMR offering improved external ballistics over standard .22 LR. The threaded 1/2x28 muzzle and folding stock also make it a viable host for a rimfire suppressor, ideal for controlling pest populations without disturbing neighbors.

How does the Christensen Arms MPR compare to the Stevens 334?

The Christensen Arms MPR is better for modularity and precision shooting, while the Stevens 334 is a more traditional and economical hunting rifle. The MPR's fully adjustable aluminum chassis and match-grade trigger offer a distinct advantage for positional shooting and ergonomic tuning that a standard synthetic stock like on the Stevens 334 cannot match. You pay for that capability, as the MPR costs nearly three times more, but you're investing in a system, not just a firearm.

What does it weigh and what are the dimensions?

The rifle weighs 5.8 pounds (92.8 oz) without an optic, with a folded length of approximately 27.5 inches. The 16-inch carbon fiber barrel contributes significantly to keeping the weight under 6 pounds, while the 7075 aluminum chassis adds necessary rigidity without excessive mass. When unfolded, the overall length is 35.5 inches, and the length of pull is adjustable over a 1.5-inch range to fit most shooters from a youth to a full-size adult.

Who is this NOT for?

This rifle is not for the budget-conscious plinker or someone seeking a classic hunting rifle aesthetic. At $1,799.99, its cost of entry is justified by its materials and precision, not by its ability to simply fire a round. If your use case involves occasional shooting from a bench or a desire for a walnut-stocked field gun, you'd be better served by a traditional bolt-action like those in our Stevens 334 series. The MPR's value is unlocked by those who will use its adjustability and accuracy.

What's in the box?

You receive the complete rifle, one Ruger BX-1 compatible 10-round magazine, and a thread protector. Christensen Arms does not include a case or basic optic mount, as they assume the purchaser is investing in this platform and will source a high-quality scope ring set and a fitted transport case. The paperwork includes the manual and a warranty card, which is standard for the industry but notable for its limited lifetime coverage on the chassis and action.

Is the Christensen Arms MPR Rimfire worth it at $1799.99?

Yes, it is worth the price for a shooter who demands a suppressor-ready, chassis-based rimfire trainer or hunter. You are paying for the carbon-wrapped barrel technology, the machined 7075 aluminum chassis, and the TriggerTech trigger—components that individually command a premium. When you consider that a comparable custom build using aftermarket parts would likely exceed this price by several hundred dollars and require fitting, the MPR's out-of-the-box readiness justifies its cost for its specific niche.
