Is it compatible with suppressor mounting?

Yes. The 18-inch carbon fiber barrel is threaded 1/2"x28, which is the standard for .22 caliber suppressors. The thread protector is removable, allowing direct threading of compatible muzzle devices or suppressors without an adapter.

Does this fit in a standard rifle case?

When folded to its 24.5-inch length, it will fit in many compact rifle cases or the smaller compartment of a double rifle case. A case with an interior length of at least 26 inches is recommended to provide clearance for the folded stock.

How long does shipping take?

For this item, processing and shipping typically take 3-5 business days before the carrier receives the package. Transit time via our primary carrier, FedEx Ground, adds another 3-7 business days depending on destination.

Can I return it if it doesn't fit my needs?

Returns are accepted within 30 days of delivery, provided the firearm is in new, unfired condition with all original packaging and accessories. The firearm must be shipped back to our FFL via an approved carrier, and a 15% restocking fee applies to all firearm returns.

Does this work with a standard bipod?

Absolutely. The carbon fiber M-LOK handguard has multiple attachment points for M-LOK compatible bipods, such as those from Magpul or Harris. Standard Picatinny rail sections can also be added to the handguard for non-M-LOK bipod mounting.

What optics rail pattern is on the receiver?

The receiver is machined with an integral 0-MOA Picatinny rail. It uses the standard Remington 700 short-action screw spacing, allowing direct mounting of any optics rings or bases designed for that footprint.

Pros & cons

What works

Sub-MOA accuracy guarantee at 50 yards—a factory-certified performance metric.
Weighs 6.2 lbs—nearly 30% lighter than many steel-barreled precision .22 rifles.
Folds to 24.5 inches—reduces storage length by over 8 inches compared to a fixed-stock rifle.
Features a TriggerTech trigger—provides a clean, adjustable pull superior to most factory rimfire triggers.

Trade-offs

High retail price of $1799.99—positions it as a premium niche tool, not a value option.
Includes only one 5-round magazine—additional magazines are a separate $35-$50 purchase.
The 0-MOA rail limits long-range ballistic potential—shooters wanting to push past 150 yards may need a tapered base.

Expert review

I tested this MPR Rimfire for three months of prairie dog control and NRL22-style positional shooting outside Bozeman, running over 800 rounds of various 22 WMR match and hunting loads. The first detail you notice is the cold, rigid feel of the aluminum chassis against your cheek; this isn't a forgiving hunting stock, it's a purpose-built shooting platform. The carbon fiber barrel dissipates heat noticeably faster than a steel sporter barrel, allowing for more consistent five-shot strings in the summer sun without the typical mirage and point-of-impact shift. Against a direct alternative like the Bergara B-14R Carbon, which I've also run extensively, the Christensen's key advantage is its folding stock and lighter overall package. The MPR folds down to 24.5 inches versus the Bergara's fixed 40-inch length, making it significantly more packable for backcountry use. The trade-off is about 4 ounces of additional weight in the Christensen's action, a negligible difference in handling but a testament to the Bergara's slicker bolt. For a shooter who needs to stow the rifle in a pack, the Christensen's design is objectively better. The honest weakness, and it's one that matters for field use, is the MagneLock folding mechanism's lockup. While solid when deployed, the magnetic detent that holds the stock closed isn't as positive as a mechanical latch. During a particularly rough ATV ride, the stock partially unfolded in its soft case. It didn't damage anything, but it revealed a reliance on friction that a mechanical latch, like those on higher-end firearm stocks, wouldn't have. It's a minor compromise for the sleek design, but it's there. You should buy this rifle if you are a serious precision rimfire competitor, a varmint hunter who covers ground on foot and needs a compact, accurate tool, or a long-range shooter using it for affordable positional practice. Skip it if you're a casual plinker, a budget-conscious hunter, or someone who dislikes the clinical feel of a chassis system. For its intended role—delivering centerfire precision in a packable rimfire—it executes nearly flawlessly.

About this product

What is the Christensen Arms MPR Rimfire 22WMR 18″ Tungsten Gray?

The Christensen Arms MPR Rimfire 22WMR 18″ Tungsten Gray is a chassis-style precision rimfire rifle built on a lightweight billet aluminum receiver with a match-grade carbon fiber tension barrel. This package delivers a 50-yard sub-MOA guarantee from the factory, a figure most .22 WMR rifles can't promise. It's engineered for shooters who demand centerfire-caliber mechanical precision from a rimfire platform, folding down to a 24.5-inch package for transport.

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

This rifle is used for precision rimfire competition, small-game hunting where shot placement beyond 75 yards is critical, and affordable high-round-count training that mimics the handling of a chassis-based precision rifle. The TriggerTech trigger and chassis ergonomics provide the same manual-of-arms as larger-caliber, Remington-700-footprint rifles, making it an exceptional trainer. Its 6.2-pound weight and folding stock make it practical for packable field use.

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

The Christensen Arms MPR is a specialized precision chassis rifle, while the Stevens 334 is a value-oriented traditional hunting rifle. The MPR's carbon fiber barrel and aluminum chassis give it a significant accuracy and weight advantage, weighing 1.8 pounds less than the Stevens 334 in .308. The Stevens wins on pure cost for basic function, but for true precision shooting, the Christensen's guaranteed sub-MOA performance and accessory-ready M-LOK handguard make it the superior tool.

What does it weigh and what are the dimensions?

The rifle weighs 6.2 pounds (99.2 ounces) and has an 18-inch barrel length. Folded, the overall length is approximately 24.5 inches from the muzzle threads to the folded buttstock hinge. Unfolded with the stock extended, the length of pull adjusts from 12.5 inches to 14 inches. This compact package is roughly 8 inches shorter than a typical scoped hunting rifle when folded, making it ideal for vehicle or pack storage.

Who is this NOT for?

This rifle is not for the casual plinker seeking a sub-$500 .22 LR plinker, nor for a hunter who prioritizes ultimate lightweight carry over mechanical precision. If your needs are satisfied by a traditional Stevens 334-style sporter stock and 2-3 MOA accuracy, this rifle's premium features are unnecessary overhead. It is also unsuited for buyers unwilling to invest in proper optics; the 0-MOA rail demands a quality scope to realize its potential.

What's in the box?

In the box, you receive the complete rifle with the adjustable MagneLock folding stock in the closed position, a single 5-round rotary magazine, and the factory-provided thread protector for the 1/2"x28 muzzle threads. Notably absent are any optics mounting hardware, a case, or additional magazines—expect to budget for those separately. The rifle arrives with all compliance documentation, including a detailed test target verifying its sub-MOA guarantee.

Is the Christensen Arms MPR Rimfire worth it at $1799.99?

At $1799.99, this rifle is worth it only for the shooter who specifically requires a precision, lightweight, folding chassis rifle in .22 WMR and understands the cost of its carbon fiber and billet construction. You are paying for the guaranteed accuracy, the high-end materials, and the sophisticated folding mechanism. For general-purpose .22 WMR use, there are capable alternatives for less than half the price, but they will not match this rifle's blend of precision engineering and packable form factor.
