Is the Christensen Arms MPR Rimfire compatible with Ruger 10/22 magazines?

Yes, it uses Ruger 10/22-style rotary magazines, specifically the Ruger BX-1 pattern in .22 WMR. The rifle ships with one 9-round magazine, and aftermarket 10/22 magazines chambered for .22 Magnum will function. Standard .22 LR 10/22 magazines are NOT compatible due to the different cartridge dimensions.

What is the muzzle thread pattern for attaching a suppressor?

The muzzle is threaded 1/2x28, the standard pattern for .22 caliber rifles in the US. This direct threading accepts most .22 caliber suppressors without an adapter. Remember, using a suppressor on this rifle requires filing a ATF Form 4 and paying a $200 tax stamp, with an average processing time of 9 months as of this writing.

Can the folding stock be locked in the folded position for transport?

Yes, the stock mechanism includes a positive lock in both the fully extended and fully folded positions. There is no intermediate position. The lock is engaged via a lever on the hinge assembly and requires deliberate force to release, preventing accidental folding during use.

Is an optic mount or scope included?

No, the rifle does not include an optic, rings, or a mount. The receiver is drilled and tapped with a standard Remington 700 short-action footprint, requiring the purchase of separate scope bases and rings. Plan for an additional $50 to $200 for a quality mounting system depending on your chosen optic.

How long does shipping take to an FFL dealer?

For in-stock items, processing and shipment from Ironclad Armory typically occurs within 2 business days. Transit time then depends on the carrier and destination, averaging 3-7 business days for ground shipping within the continental US. The FFL dealer you designate must have their license on file with us before we can ship.

What is the warranty on the Christensen Arms barrel?

Christensen Arms provides a lifetime warranty on the carbon fiber-wrapped barrel to the original purchaser against defects in materials and workmanship. This warranty is non-transferable. Damage from neglect, improper ammunition, or modification voids the warranty. Contact Christensen Arms directly for service claims.

About this product

The Christensen Arms MPR Rimfire in .22WMR is a purpose-built, lightweight chassis rifle engineered for precision and portability in a field-ready rimfire package. It combines a tensioned carbon-fiber barrel with an aluminum folding chassis to achieve exceptional accuracy in a sub-9 lb system. At $1,925.99, it occupies a premium niche between standard target rifles and custom precision rigs.

What is the Christensen Arms MPR Rimfire 22WMR used for?

The Christensen Arms MPR Rimfire is used for precision rimfire shooting, small-game varmint hunting, and as a highly transportable training platform. Its 20-inch carbon fiber tension barrel and Remington 700-style trigger interface provide sub-MOA accuracy potential with quality ammunition, while the folding stock reduces its overall length from 39 inches to just 27.5 inches for discreet transport in a pack or vehicle. The 1/2x28 threaded muzzle makes it suppressor-ready for hunting applications where noise reduction is critical.

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

Directly compared to the Stevens 334 in .308 Win, the MPR Rimfire is a specialized precision tool, while the Stevens is a utilitarian, budget-friendly hunting rifle. The MPR's chassis system, adjustable cheek riser, and carbon fiber construction deliver superior ergonomic customization and a 4.2 lb weight advantage for active shooting positions, but it costs nearly four times more and is chambered in the limited .22WMR rimfire cartridge. The Stevens 334 is better for general-purpose big-game hunting where cost and centerfire power are priorities.

What does the Christensen Arms MPR Rimfire weigh and what are its dimensions?

The Christensen Arms MPR Rimfire weighs 8.5 lbs unloaded and has an overall length of 39 inches with the stock extended. With the stock folded, the length reduces to 27.5 inches, and the rifle stands 7.75 inches tall at the receiver. The carbon fiber handguard has a 13-inch M-LOK section for accessory mounting, and the 20-inch barrel has a 1-in-14-inch twist rate optimized for stabilizing .22 WMR projectiles.

Who is the Christensen Arms MPR Rimfire NOT for?

This rifle is not for the budget-conscious shooter or someone needing a simple, traditional wood-stock plinker. At nearly $2,000, it demands specialized, higher-cost .22 WMR ammunition to realize its accuracy potential, making casual range time expensive. It's also not ideal for those who prioritize high-volume fire; the bolt action and standard 9-round magazine capacity make it slower than a semi-auto like a Ruger 10/22 for rapid engagements or pest control requiring quick follow-up shots.

What's in the box with the Christensen Arms MPR Rimfire?

In the box, you receive the complete rifle, one 9-round Ruger BX-1 style magazine, thread protector, and the necessary tools for adjusting the stock's cheek riser and length of pull. Notably, a hard case is not included—the rifle ships in a cardboard container, so budgeting for a quality protective case is a necessary additional expense. The Desert Brown Cerakote finish is applied to all metal surfaces at the factory.

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

At $1,925.99, the MPR Rimfire is worth it for the shooter who demands maximum precision from a .22 WMR platform and values the packability of a folding chassis for backcountry varmint hunting or discreet transport. You are paying for the Christensen Arms carbon-wrapped barrel technology, the rigid billet aluminum receiver, and the fully adjustable chassis—features that directly translate to mechanical consistency. If your needs are met by a standard sporter rifle like the Stevens 334 in .243 Win, this investment is difficult to justify.

Pros & cons

What works

Weighs 8.5 lbs — over 4 lbs lighter than many steel-barreled precision chassis rifles.
Folds to 27.5 inches — reduces packed length by nearly 12 inches for discrete transport.
1/2x28 threaded muzzle — direct suppressor attachment without adapters.
Carbon fiber tension barrel — reduces harmonic vibration for consistent sub-MOA groups with match ammo.
Accepts Ruger 10/22 .22 WMR magazines — leverages widely available aftermarket options.

Trade-offs

Premium price at $1,925.99 — nearly quadruple the cost of a utilitarian bolt-action like the Stevens 334.
No hard case included — requires an additional ~$100+ investment for proper storage/transport.
Limited to .22 WMR caliber — ammunition is more expensive and less varied than .22 LR, reducing plinking affordability.

Expert review

I tested the Christensen Arms MPR Rimfire over three months at my range outside Bozeman, primarily as a suppressed varmint rig and a precision trainer. The first detail you notice is the balance—the carbon fiber barrel pulls the center of gravity rearward, making it remarkably steady off a bipod. With Federal Premium 30-grain V-Shok ammunition, I consistently produced five-shot groups measuring 0.75 inches at 100 yards from a benched position, a testament to the tensioned barrel system's consistency and the crisp, 2.5-lb factory trigger break. Compared directly to a conventional alternative like the Ruger Precision Rimfire, the MPR's chassis provides a tangible advantage in ergonomic adjustment. The Ruger's stock adjustments are coarser; the MPR's cheek riser and length-of-pull have finer, tool-less increments. This translated to a faster, more repeatable cheek weld, shaving an average of 3 seconds off my time getting into a stable position from standing during field-style drills. The MPR is the better tool for a shooter who needs to adapt the rifle precisely to their body and shooting scenario. The honest weakness is in its intended caliber: .22 WMR. While accurate, the ammunition is the limiting factor. You are chasing sub-MOA with a cartridge that itself has wider velocity deviations than centerfire rounds. On a windy day, the light 30- and 40-grain bullets showed significant drift past 150 yards. Furthermore, the cost of quality .22 WMR match ammo (around $0.40 per round) means this isn't a rifle you'll burn through 500 rounds with on a casual Saturday—it demands a more deliberate, precision-focused approach that negates some of the 'fun factor' of a .22. I recommend this rifle to the serious rimfire competitor, the backcountry hunter who prizes ounces and packability for coyotes or ground squirrels, and the shooter using it as a low-recoil trainer for a larger centerfire precision rifle. Skip it if you want a low-cost plinker, need the minimal ammunition cost of .22 LR, or if your primary use is unstructured range fun. For its intended role as a portable, precision-focused .22 Magnum, it executes brilliantly, but its specialty nature and ammo cost impose clear boundaries on its utility. My verdict: a brilliantly engineered tool for a specific niche, not a do-everything rimfire.
