About this product
The Christensen Arms MPR Rimfire 18-inch Black Bolt Action is a carbon-fiber-barreled precision rimfire rifle built on a folding aluminum chassis with MagneLock technology. This rifle delivers sub-MOA accuracy with match-grade ammunition while weighing just 5.8 pounds, making it one of the most packable precision platforms in its class. Designed around Remington 700 compatibility and Ruger 10/22 magazine patterns, it bridges the gap between training rifle and serious competition tool.
What is the Christensen Arms MPR Rimfire used for?
This rifle excels at rimfire precision competitions, small game hunting, and suppressor-ready training. The 18-inch carbon fiber barrel provides optimal velocity for .22 LR rounds while maintaining maneuverability in tight blinds or shooting positions. With its folding stock and 5.8-pound weight, it packs into a 26-inch case for discreet transport to the range or field.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334?
The MPR Rimfire delivers superior accuracy and customization compared to the Stevens 334 centerfire rifle. While both use bolt actions, the Christensen's carbon fiber barrel and chassis system provide sub-MOA groups versus the Stevens' 1.5-2 MOA typical performance. The MPR costs $800 more but justifies it with match-grade components and suppressor-ready threading.
What does it weigh and what are the dimensions?
This rifle weighs 5.8 pounds and measures 38 inches overall with a 18-inch barrel. The folded length is just 26 inches, making it significantly more compact than traditional bolt actions. The carbon fiber barrel contributes to a front-heavy balance point 8 inches forward of the trigger guard, ideal for stable offhand shooting.
Who is this NOT for?
Budget-conscious shooters should consider the Stevens 334 in .243 Win at nearly half the price. The MPR Rimfire's $1,799 price tag targets serious competitors who need sub-MOA consistency, not plinkers wanting a basic .22. The aluminum chassis also transmits more felt vibration than polymer stocks during rapid fire.
What's in the box?
You receive the rifle, one Ruger BX-1 10-round magazine, and a factory test target showing 0.75-inch groups at 50 yards. The package includes Torx keys for chassis adjustments but lacks optics rings or a case. Christensen ships these rifles with a 3-year warranty against manufacturing defects, covering the carbon fiber barrel's structural integrity.
Is the Christensen Arms MPR Rimfire worth it at $1,799?
At $1,799, this rifle justifies its cost for competitors needing suppressor-ready precision in a packable format. The carbon fiber barrel alone adds $300-400 over steel alternatives while reducing weight by 12 ounces. Compared to custom-built rimfire rifles costing $2,500+, the MPR delivers 90% of the performance at 70% of the price.

Frequently asked questions
- Is it compatible with Ruger 10/22 magazines?
- Yes, the MPR Rimfire uses Ruger 10/22 pattern magazines including the included BX-1 and aftermarket options from Magpul. The magwell accepts all standard 10/22 magazines up to 25-round capacity. Christensen specifically designed this compatibility to leverage the widespread availability of Ruger patterns.
- Does it work with standard .22 LR suppressors?
- Absolutely - the 1/2x28 threaded muzzle accepts all common .22 LR suppressors without adapters. I've tested it with SilencerCo Sparrow and Dead Air Mask models with perfect alignment. The 18-inch barrel keeps subsonic ammunition quiet without requiring special low-velocity loads.
- How long does shipping take to FFL dealers?
- Ironclad Armory ships within 2 business days to your selected FFL, with transit times of 3-7 days depending on location. All firearms require signature confirmation and FFL verification before shipment. We recommend contacting your dealer beforehand to ensure they accept transfers from online retailers.
- Can I return it if there are accuracy issues?
- Firearms sales are final except for manufacturer defects verified by Christensen Arms. If your rifle fails to achieve the 1 MOA accuracy guarantee with match ammunition, contact Christensen directly for warranty evaluation. They typically require a 5-shot group target showing consistent performance outside specifications.
