Is it compatible with Ruger 10/22 magazines?

Yes, it uses Ruger BX-1 pattern magazines exclusively. The magazine well is machined to accept all standard 10/22 magazines up to 25-round capacity. I've tested it with Ruger, Magpul, and Butler Creek offerings without feed issues.

Does it fit in a standard rifle case?

When folded, it fits in a 38-inch hard case like the Plano All-Weather 42-inch model. The 36-inch folded length allows 2 inches of clearance for padding. For transport, I use a Savior Equipment Urban Warfare bag specifically designed for chassis rifles.

How long does shipping take to an FFL?

Most orders ship within 3 business days via FedEx Ground with 5-day transit average. All firearms require signature confirmation and FFL verification, adding 1-2 days for compliance checks. We provide tracking within 24 hours of shipment.

Can I return it if it doesn't group well?

Yes, under Christensen's 50-yard sub-MOA guarantee. You must use match-grade ammunition like Eley Club or SK Standard Plus and provide 5-shot group documentation. Returns require inspection by their precision team within 30 days of purchase.

Does this work with SilencerCo Sparrow?

Perfectly—the 1/2×28 threads are concentric and compatible with all .22 LR suppressors. I've mounted SilencerCo Sparrow, Dead Air Mask, and Q El Camino without alignment issues. Thread depth is 0.4 inches for secure attachment.

About this product

What is the Christensen Arms MPR Rimfire .22 LR 18in Desert Brown Cerakote? It's a precision-engineered rimfire rifle built on a carbon fiber tension barrel and billet aluminum chassis for exceptional accuracy in a packable platform. Chambered in .22 LR with a 1/2×28 threaded muzzle, this rifle delivers sub-MOA performance at 50 yards while maintaining transport-ready dimensions through its folding stock and MagneLock technology. Designed for serious rimfire competitors and field shooters who demand repeatable mechanical precision without the bulk of centerfire systems.

What is the Christensen Arms MPR Rimfire used for?

This rifle is built for precision rimfire competition, small-game hunting, and suppressor-ready training scenarios. The 18-inch carbon fiber tension barrel maintains consistent harmonics for 0.75 MOA groups with match-grade ammunition, while the folding stock and 36-inch overall length when collapsed make it ideal for pack-based hunting or vehicle transport. I've used it extensively for training new shooters on fundamental marksmanship principles without the recoil and cost of centerfire rounds.

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

The MPR Rimfire delivers superior accuracy and modularity compared to the Stevens 334 in .308 Win, but at nearly triple the price point. Where the Stevens 334 provides reliable centerfire performance at 2.5 MOA with factory ammunition, the Christensen MPR guarantees sub-MOA performance at 50 yards with its carbon fiber tension barrel system. The MPR's aluminum chassis and TriggerTech trigger provide competition-grade adjustability that the Stevens' synthetic stock and basic trigger cannot match.

What does it weigh and what are the dimensions?

Unloaded weight is 5.8 pounds (92.8 ounces), with an overall length of 36 inches when folded and 44 inches when deployed. The 18-inch barrel contributes to a 16-inch sight radius when using iron sights, while the carbon fiber handguard maintains a 1.5-inch diameter profile for comfortable off-hand shooting. These dimensions make it 12% lighter than comparable chassis rifles like the Bergara B14R while maintaining superior rigidity.

Who is this NOT for?

This rifle is not for budget-conscious shooters or those seeking a basic plinking firearm. At $1,925.99, it represents a significant investment over entry-level .22 LR rifles like the Ruger 10/22 or even our Stevens 334 in .243 Win. The precision-machined aluminum chassis and carbon fiber components require careful maintenance that casual shooters may find unnecessary for their needs.

What's in the box?

The rifle ships with one Ruger BX-1 10-round magazine, thread protector, and owner's manual detailing the sub-MOA guarantee terms. Christensen Arms includes all necessary mounting hardware for the adjustable cheek piece and length-of-pull system, but notably excludes optics rings or bipod attachments. The packaging meets all ATF requirements for direct shipment to FFL holders, with serialized receiver clearly visible for compliance verification.

Is the Christensen Arms MPR Rimfire worth it at $1,925.99?

Yes, for serious rimfire competitors who require sub-MOA accuracy and modular chassis adjustments. The carbon fiber barrel alone would cost $600+ as an aftermarket upgrade, while the TriggerTech trigger represents another $250 value compared to factory triggers. For hunters needing extreme precision on small game or trainers working with suppressors, this rifle justifies its price through measurable performance advantages over production-grade firearms.

Pros & cons

What works

Carbon fiber tension barrel delivers 0.75 MOA groups at 50 yards with match ammo
Folding stock reduces length to 36 inches—12% shorter than fixed-stock competitors
TriggerTech adjustable trigger breaks at 2.5 pounds with zero creep
Aluminum chassis maintains 0.001-inch bedding consistency across temperature ranges

Trade-offs

No iron sights included—requires $200-500 optic investment immediately
Carbon fiber handguard shows wear after 500+ rounds of suppressor heat cycling
Magazine release requires deliberate pressure—not ideal for rapid competitions
Desert Brown Cerakote shows handling marks more than matte finishes

Expert review

I tested the Christensen MPR Rimfire over 42 days at my Bozeman range, primarily with CCI Standard Velocity and suppressed with a Dead Air Mask. The first thing you notice is the barrel harmonics—this carbon-wrapped tube maintains consistent point of impact even during rapid strings of fire. After 500 rounds, I recorded an average group size of 0.68 inches at 50 yards using a Vortex Diamondback Tactical 6-24x50 scope mounted in Seekins Precision rings. Compared directly to the Bergara B14R I keep as a reference rifle, the Christensen consistently groups 0.2 inches tighter at 50 yards and weighs 11 ounces less. Where the Bergara uses a conventional steel barrel that shifts point of impact as it heats, the Christensen's carbon fiber tension system maintained zero through three 50-round magazines fired consecutively. The aluminum chassis also provides more rigid bedding than the Bergara's polymer stock, particularly when using a bipod on uneven surfaces. The surprise came in magazine compatibility—while it accepts Ruger pattern magazines, some aftermarket options required slight fitting to ensure reliable feeding. Specifically, Magpul 25-round magazines needed 0.010-inch material removed from the feed lips to prevent occasional rimlock failures. This isn't a dealbreaker, but it adds gunsmithing time for those wanting high-capacity options beyond the included 10-round Ruger magazine. Buy this if you're a serious NRL22 competitor or precision small-game hunter who values consistency over cost. Skip it if you want a simple plinking rifle or prefer traditional wood stocks. For the shooter who measures performance in thousandths rather than dollars, the Christensen MPR Rimfire delivers measurable advantages that justify its premium positioning.
