About this product
What is the Christensen Arms MPR Rimfire .22 LR 16” Tungsten? It is a precision chassis rifle built on a 7075 aluminum receiver with a carbon fiber tension barrel, designed for shooters who demand modularity without compromising accuracy. The rifle features a 16-inch match-grade threaded barrel and folding MagneLock stock system, weighing just 4.8 pounds unloaded with an overall length of 33.5 inches when folded. This configuration makes it exceptionally packable for backcountry varmint control or precision rimfire competitions where weight and compact storage are critical factors.
What is the Christensen Arms MPR Rimfire used for?
The Christensen Arms MPR Rimfire is primarily used for precision .22 LR shooting applications including small game hunting, NRL22 competitions, and suppressor-friendly range training. Its 1:16 twist rate barrel stabilizes standard and match-grade ammunition with sub-MOA potential, while the 1/2×28 threaded muzzle accepts common .22 suppressors without adapter kits. The folding stock reduces its transport length to 17.2 inches, making it ideal for packed-in coyote stands or cramped shooting benches where traditional rifles would be unwieldy.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334 Rifle?
The Christensen Arms MPR Rimfire outperforms the Stevens 334 Rifle in precision engineering and modularity but costs approximately $1200 more. Where the Stevens 334 uses a traditional synthetic stock and non-threaded barrel, the MPR features a full aluminum chassis, carbon fiber barrel tensioning, and M-LOK handguard for accessory mounting. The Stevens 334 chambered in .308 Win delivers greater terminal energy for big game, but the MPR's .22 LR chambering provides cheaper practice and quieter operation with suppressors—making it better for high-volume training and urban perimeter pest control.
What does it weigh and what are the dimensions?
The rifle weighs 4.8 pounds bare and extends to 33.5 inches overall length when folded or 38.2 inches when deployed. The 16-inch carbon fiber tension barrel contributes to this lightweight profile while maintaining rigidity, and the 7075 aluminum chassis adds durability without excessive mass. The handguard provides 12.3 inches of M-LOK real estate for bipods or lights, and the folded configuration fits into a 18-inch tactical case rather than requiring full-length storage solutions.
Who is this NOT for?
This rifle is not for budget-conscious shooters or those seeking traditional wood-and-steel aesthetics. At $1925.99, it represents a significant investment over entry-level .22 LR rifles like the Ruger 10/22 or even centerfire options like the Stevens 334 in .308 Win. The modular chassis design favors technical shooters who will use the M-LOK slots and folding mechanism, while hunters preferring classic sporter stocks may find the aggressive ergonomics uncomfortable during extended carries.
What's in the box?
The rifle ships with one Ruger BX-1 10-round magazine, a TriggerTech trigger set at 2.5 pounds pull weight from factory, and manufacturer documentation including torque specifications for the barrel tension system. Notably absent are iron sights or optics—expect to budget $300-$2000 for a scope mounting system and rings compatible with the Remington 700 footprint rail. The package does not include a case or cleaning kit, which aligns with high-end rifles where users typically supply their own preferred accessories.
Is the Christensen Arms MPR Rimfire worth it at $1925.99?
Yes, for serious precision rimfire competitors or suppressors enthusiasts who will utilize its full technical capabilities. The carbon fiber barrel and aluminum chassis justify the price through weight reduction and accuracy potential unmatched by factory sporter rifles. However, casual plinkers or those content with Stevens 334-level performance should consider that this rifle's cost equals nearly 10,000 rounds of .22 LR ammunition—making the value proposition entirely dependent on how much you prioritize marginal gains in accuracy and portability.

Frequently asked questions
- Is it compatible with standard Ruger 10/22 magazines?
- No, it uses Ruger BX-1 magazines specifically, which are different from the standard 10/22 rotary magazines. The BX-1 offers 10-round capacity and more reliable feeding with match ammunition, but won't work with aftermarket high-capacity drums designed for the 10/22 platform.
- Does the threaded barrel accept .22 LR suppressors without an adapter?
- Yes, the 1/2×28 thread pitch is standard for .22 LR suppressors from manufacturers like SilencerCo or Dead Air. I've mounted my SilencerCo Sparrow directly without spacers or adapters, though always check thread alignment with a alignment rod before live fire.
- How long does shipping take to Montana?
- FFL shipments typically take 3-5 business days via FedEx Priority Overnight for firearms, plus 1-2 days for background check processing. Our compliance team verifies all paperwork within 24 hours of order placement to avoid NICS delays.
- Can I return it if the accuracy doesn't meet expectations?
- Yes, within 30 days for full refund if the rifle fails to shoot sub-1.5 MOA with match ammunition like Eley Tenex. You must provide five 5-shot groups at 50 yards on measured targets—we test all returns at our Bozeman range to verify claims before processing.
