Expert review
About this product
The Christensen Arms MPR Rimfire is a precision bolt-action rimfire rifle featuring a carbon fiber tension barrel and aluminum folding chassis, designed for shooters who demand competition-grade accuracy in a packable platform. At 16 inches with a threaded muzzle and 8.35 pounds, it bridges tactical rimfire and field use with exceptional modularity. Built on a Remington 700 footprint, it accepts aftermarket triggers and optics while folding to 28 inches for discreet transport.
What is the Christensen Arms MPR Rimfire used for?
This rifle excels in NRL22 competition, small-game hunting, and suppressor-ready range training where its 1/2×28 threaded barrel and sub-MOA accuracy matter most. The folding chassis and 8.35-pound weight make it ideal for pack-based varmint control or backcountry carry, while the TriggerTech trigger and 0-MOA rail support precision optic setups. M-LOK handguard mounting supports lights or bipods for low-light hunts or timed stages.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334?
The MPR Rimfire outperforms the Stevens 334 in accuracy potential and modularity, with its carbon fiber barrel maintaining consistent groups under 0.75 MOA versus the Stevens' typical 1.5-2 MOA with factory ammunition. Where the Stevens 334 serves as an entry-level hunting rifle, the MPR Rimfire is a purpose-built competition chassis with adjustable length of pull (12.5–14.5 inches), folding stock, and premium TriggerTech components. You're paying $1,799.99 for match-grade performance, not basic field functionality.
What does it weigh and what are the dimensions?
Unloaded weight is 8.35 pounds with a 16-inch barrel and folded length of 28 inches for transport or storage. Extended length measures 36.5 inches overall, with a 12.5–14.5 inch adjustable length of pull and cheek riser accommodating most shooters. The carbon fiber handguard shaves weight while maintaining rigidity across its 10-inch span, critical for bipod stability during sustained fire.
Who is this NOT for?
Budget-conscious buyers should avoid this rifle—the $1,799.99 price reflects match-grade components that outperform cheaper alternatives like the Stevens 334 but aren't necessary for plinking or casual use. Those needing immediate NFA compliance should note the 16-inch barrel avoids SBR registration but requires a tax stamp for suppressor use, adding $200 and a 9-month wait. Traditional hunters preferring walnut stocks may find the tactical chassis excessively complex for field carry.
What's in the box?
You receive the rifle with one Ruger BX-1 10-round magazine, factory manual, and a thread protector for the 1/2×28 muzzle—no optic, bipod, or case included. The chassis arrives with MagneLock engaged, folding mechanism lubricated, and trigger set to a crisp 2.5-pound break from the factory. Expect to spend another $300–$500 on a quality scope and rings to utilize its precision capability fully.
Is the Christensen Arms MPR Rimfire worth it at $1,799.99?
Absolutely, if you compete in NRL22 or demand suppressor-ready accuracy from a packable platform—the carbon fiber barrel and folding chassis justify the cost over cheaper alternatives. For hunters or plinkers, consider the Stevens 334 in .308 Win at half the price, but expect to sacrifice modularity and sub-MOA consistency. This rifle is an investment in precision rimfire performance, not a general-purpose tool.

Pros & cons
What works
- Carbon fiber barrel maintains 0.75 MOA accuracy with match ammo—half the spread of most factory rifles
- Folds to 28 inches—12 inches shorter than fixed-stock alternatives for discreet transport
- TriggerTech trigger breaks at 2.5 pounds consistently—lighter and crisper than most factory rimfire triggers
Trade-offs
- No iron sights included—adds $150–$300 for optic and mount before usable
- Chassis lacks QD sling cups—requires M-LOK or Picatinny adapters for sling mounting
- Carbon fiber handguard transmits heat during rapid fire—gloves recommended after 40 rounds consecutive

Frequently asked questions
- Is it compatible with Ruger 10/22 magazines?
- Yes, it uses Ruger BX-1 magazines exclusively—the same pattern as the 10/22, with a 10-round capacity. Aftermarket mags like Magpul X-22 may require slight fitting due to chassis tolerances. Always test feed reliability before competition use.
- Does it fit in a standard rifle case?
- Folded, it fits most 28-inch hard cases like Pelican 1700, but extended length requires a 36-inch case. Measure your existing case—if under 28 inches interior, it won't close securely. Plan for a dedicated case if transporting folded regularly.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground shipping adding 3–5 days continental US. NFA items like suppressors ship separately via compliant carriers with longer ATF wait times. Always confirm FFL availability before ordering.
- Can I return it if it doesn't group well?
- Returns require unfired condition and original packaging—once fired, it's gunsmith evaluation only. Most accuracy issues stem from ammunition choice; try 5 different .22LR brands before considering return. Ironclad's smiths test-fire each rifle with Eley Match for function check.
