Christensen Arms MPR Rimfire .22 WMR 16-inch Folding Black
About this product
The Christensen Arms MPR Rimfire .22 WMR 16-inch Folding Black is a precision bolt-action rimfire rifle built on a carbon fiber tension barrel and 7075 aluminum chassis with folding MagneLock stock. Designed for shooters who demand packable accuracy, it bridges the gap between field utility and competitive performance at 100+ yards. At 6.2 pounds with a 16-inch barrel, it's specifically chambered for .22 WMR with a 1:14 twist rate.
What is the Christensen Arms MPR Rimfire used for?
This rifle is built for precision rimfire competition, small-game hunting, and tactical training where compact transport matters. The folding stock reduces overall length to 24 inches when collapsed, making it ideal for pack-based varminting or vehicle-ready scenarios. With its match-grade barrel and TriggerTech trigger, it maintains sub-MOA accuracy with quality ammunition at distances where .22 WMR remains effective.
How does the Christensen Arms MPR Rimfire compare to the Stevens 334 Rifle?
The Christensen MPR outperforms the Stevens 334 in .308 Win in weight and portability, being 3.8 pounds lighter and featuring a folding stock versus fixed synthetic. However, the Stevens 334 delivers significantly more stopping power for medium game and longer range ballistics, making the Christensen better for rimfire-specific disciplines where centerfire recoil and report are undesirable.
What does it weigh and what are the dimensions?
The rifle weighs 6.2 pounds (99.2 ounces) with an overall length of 36 inches unfolded and 24 inches folded. The 16-inch barrel features a 1/2x28 thread pattern for suppressors or muzzle devices, while the chassis accepts standard Remington 700-style bottom metal and has an adjustable length of pull from 12.5 to 14.5 inches to fit most adult shooters.
Who is this NOT for?
This rifle isn't for budget-conscious shooters or those needing centerfire power for deer or larger game. At $1,925.99, it costs nearly four times more than entry-level .22 WMR options and lacks the energy for ethical hunting beyond small varmints. If you need penetration at 200+ yards or are building a first rifle on a tight budget, consider a Stevens 334 in .243 Win instead.
What's in the box?
You receive the complete rifle with one 5-round AICS pattern magazine, a 0-MOA Picatinny rail pre-installed, and manufacturer documentation including warranty paperwork. Unlike some competitors, it does not include optic rings, a case, or cleaning kit—expect to add $150-$300 for mounting hardware and transport protection before heading to the range.
Is the Christensen Arms MPR Rimfire worth it at $1925.99?
Yes, if you require a suppressorfriendly, folding precision rimfire platform for competition or specialized varmint control. The carbon fiber barrel and aluminum chassis justify the cost against milled steel alternatives, saving 12-18 ounces while improving heat dissipation. For recreational plinking or introductory shooting, however, a $500 bolt-action .22 WMR will deliver 80% of the performance at one-quarter the price.

Frequently asked questions
- Is it compatible with standard Remington 700 triggers?
- Yes, it uses a Remington 700 footprint and includes a TriggerTech unit rated for 2.5-4 pounds pull weight. Most aftermarket R700 triggers from Timney or Jewell will drop in without modification, though always verify compatibility with Christensen's inlet specifications first.
- Does it fit in a standard rifle case when folded?
- When folded to 24 inches, it fits most compact rifle cases designed for 26-inch internal length. For exact fit, look for cases like Plano All-Weather 36" or Pelican Vault V730, which provide 2-3 inches of padding clearance on all sides when transporting.
- How long does shipping take to Montana?
- Firearms ship via FedEx Priority Overnight to your local FFL, requiring 2-3 business days from order processing to FFL arrival. All shipments include adult signature confirmation and require FFL paperwork completion before dispatch, adding 24-48 hours to handling time.
- Can I return it if the accuracy doesn't meet expectations?
- Returns are accepted within 30 days for unfired, original condition firearms minus a 15% restocking fee. Once fired, accuracy claims go through Christensen Arms' warranty, which requires proof of sub-MOA failure with match ammo and may involve barrel inspection at their Utah facility.
