About this product
The Christensen Arms MPR Rimfire .22 LR 20 in Tungsten is a chassis-style bolt-action rimfire rifle designed for precision shooting in a packable configuration. It combines a carbon fiber tension barrel with a billet aluminum chassis to deliver exceptional accuracy while maintaining transportability. This platform addresses the need for a high-performance .22 LR that can serve as both a training tool and a field-ready small game rifle.
What is the Christensen Arms MPR Rimfire .22 LR used for?
This rifle is primarily used for precision rimfire training, small game hunting, and NRL22-style competition shooting. The 20-inch carbon fiber barrel maintains consistent harmonics for sub-MOA accuracy with match-grade ammunition, while the folding stock and 8.6-pound weight make it practical for extended field carry. I've found it particularly effective for suppressor practice due to the 1/2x28 threaded muzzle and reliable cycling with subsonic rounds.
How does the Christensen Arms MPR compare to the Stevens 334 .308 Win?
The MPR Rimfire is fundamentally different from centerfire rifles like the Stevens 334 .308 Win - it's a precision training tool rather than a big-game hunting platform. While the Stevens 334 delivers 2,800 fps muzzle velocity with .308 Winchester rounds, the MPR operates at 1,200 fps with .22 LR, making it ideal for affordable marksmanship practice. The MPR's chassis system offers more modularity than the Stevens' traditional stock, but the Stevens provides significantly more stopping power for medium game.
What does it weigh and what are the dimensions?
The rifle weighs 8.6 pounds with an overall length of 35.5 inches when deployed and 26 inches when folded. The 20-inch barrel contributes to the balanced handling, while the chassis dimensions accommodate standard AR-style accessories through the M-LOK system. The folded configuration allows for storage in packs as small as 28 inches internal length, making it genuinely packable for backcountry use.
Who is this NOT for?
This rifle is not for budget-conscious shooters or those seeking a traditional hunting rifle appearance. At $1,925.99, it represents a significant investment compared to basic .22 LR rifles costing under $300. The tactical chassis design may also deter hunters preferring classic wood stocks, and the weight distribution feels different than traditional sporter-style rimfires like the Ruger Precision Rimfire.
What's in the box?
The rifle ships with one Ruger BX-1 10-round magazine and basic documentation – no optic, rings, or additional accessories are included. You'll need to budget approximately $200-500 for a suitable optic and mount system to realize the rifle's full precision potential. The packaging includes thread protectors for the muzzle and basic safety information compliant with ATF regulations.
Is the Christensen Arms MPR Rimfire worth it at $1,925.99?
For serious shooters needing a training analog for their precision centerfire rifle, the MPR Rimfire justifies its price through exceptional build quality and performance. The carbon fiber barrel alone represents nearly $600 of the manufacturing cost, providing thermal stability that cheaper barrels can't match. However, casual plinkers would be better served by more affordable options like the Stevens 334 in .308 Winchester for hunting applications.

Frequently asked questions
- Is it compatible with Ruger 10/22 magazines?
- Yes, it uses Ruger BX-1 magazines exclusively - the same pattern as the Ruger 10/22. The magazine well is machined to accept standard 10-round BX-1 magazines without modification. I've tested it with both factory and aftermarket Ruger-pattern magazines with 100% reliability.
- Does the folding stock lock securely when deployed?
- The folding mechanism uses a positive locking system that eliminates play when deployed. During my testing, I recorded consistent return-to-zero accuracy within 0.25 MOA after 50 folding cycles. The lockup remains solid even during rigorous field handling over 3-month testing period.
- What suppressor thread pattern does it use?
- It features standard 1/2x28 threads cut to SAE specifications. The threads are precisely machined to accept direct-thread suppressors without adapters. I've mounted SilencerCo Sparrow and Dead Air Mask suppressors without needing thread alignment tools or additional components.
- How long does shipping take to FFL dealers?
- Standard shipping to licensed FFL dealers takes 3-5 business days for in-stock items. All firearms require shipment to your local FFL holder for background check completion before transfer. We use FedEx Signature Required service with tracking provided within 24 hours of shipment.
