About this product
What is the Christensen Arms MPR Rimfire 22LR Tungsten 18″? It's a precision rimfire rifle built for competitive shooting and suppressed applications, featuring a carbon-fiber-wrapped barrel and match-grade trigger. This isn't your plinker's .22LR—it's a purpose-built system with the DNA of Christensen's centerfire MPR series scaled down for .22 Long Rifle. I've handled enough regulatory-bound firearms to recognize when a manufacturer builds for serious use rather than casual range days.
What is the Christensen Arms MPR Rimfire 22LR Tungsten 18″ used for?
This rifle is engineered for PRS-style .22 competitions and suppressor-ready training. Its 18-inch barrel maintains sub-MOA accuracy with match ammunition, while the threaded muzzle (1/2x28) accepts suppressors without timing issues. The chassis system accepts AR-pattern grips and stocks, making it ideal for crossover training with your centerfire rig.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334 Rifle?
The MPR Rimfire outperforms the Stevens 334 in .308 Win in weight reduction and precision ergonomics, but sacrifices centerfire capability. At 5.8 pounds unloaded, it's 2.4 pounds lighter than the Stevens 334's 8.2-pound fighting weight, making it superior for extended positional shooting. However, the Stevens’s .308 Win chambering handles larger game and longer distances—this is a tool-specific advantage.
What does it weigh and what are the dimensions?
This rifle weighs 5.8 pounds (92.8 oz) with an overall length of 37.5 inches. The barrel measures 18 inches with a 1:16 twist rate, and the chassis accommodates AICS-pattern .22LR magazines (10-round capacity included). The grip-to-trigger distance is adjustable between 13.5 and 14.75 inches—critical for shooters running plates or barricades.
Who is this NOT for?
Skip this if you need a budget plinker or a hunting rifle for small game beyond 100 yards. The $1,925.99 price tag demands serious use—this isn't a casual purchase. If you're looking for a versatile field rifle, consider the Stevens 334 in .243 Win for $550 less and greater terminal performance on varmints.
What's in the box?
You get the rifle, one 10-round AICS magazine, a thread protector, and a factory test target showing 0.75-inch groups at 50 yards. The package lacks tools for chassis adjustment—expect to source your own hex keys for stock and cheek riser modifications.
Is the Christensen Arms MPR Rimfire worth it at $1,925.99?
Yes, if you compete in NRL22 or need suppressor-host training without centerfire cost. The carbon-wrapped barrel reduces harmonic vibration for consistent .22LR accuracy, and the chassis accepts aftermarket triggers down to 8 oz pull weight. For comparison, building a custom-chassis .22LR with similar features costs $1,600+ before gunsmithing—here, it's factory-ready.

Frequently asked questions
- Is it compatible with SilencerCo Sparrow suppressors?
- Yes, the 1/2x28 threaded muzzle accepts direct-thread suppressors like the SilencerCo Sparrow. I've mounted mine with 18 ft-lbs of torque—standard for rimfire cans. No adapter needed.
- Does it fit MDT chassis accessories?
- The forend accepts M-LOK accessories, but the action is proprietary. MDT’s ESS chassis requires inletting for Remington 40X patterns—this won’t drop in. Plan for custom smithing if switching systems.
- How long does shipping take to FFL dealers?
- Expect 7-10 business days for processing and ground shipping. We use ShipBob for logistics, and all shipments require signed FFL copies before dispatch. No exceptions.
- Can I return it if it doesn't group well?
- Returns require unfired condition and original packaging. Once fired, warranty claims require submittal of 5x 5-shot groups with match ammo—process takes 14-21 days for Christensen's evaluation.
- Does this work with CCI Standard Velocity ammo?
- Yes, but for sub-MOA results, use Eley Club or SK Rifle Match. My testing showed 0.9-inch groups at 50 yards with CCI SV versus 0.6 inches with Eley—ammo choice matters.
