Christensen Arms MPR Rimfire .22 WMR 16-inch Folding Black

Description

The Christensen Arms MPR Rimfire .22 WMR 16-inch Folding Black is a packable precision rimfire platform that bridges the gap between a field rifle and a competition-ready bolt gun. With a carbon fiber tension match-grade barrel and a folding stock that locks up tight, this rifle delivers repeatable accuracy at distance without taking up half the safe.

Key Features

• Carbon Fiber Tension Match-Grade Barrel — The 16-inch barrel is tensioned against the receiver, reducing harmonics and delivering sub-MOA groups with .22 WMR. This matters because rimfire is notoriously sensitive to barrel whip, and this design keeps every shot consistent.
• Folding Stock with MagneLock Cheekpiece — The stock folds to the right, cutting overall length to 26 inches for packability, and the cheekpiece adjusts via MagneLock for a rock-solid weld. This matters because you need a repeatable cheek position for precision, but also a compact package for hiking to the range.
• TriggerTech Trigger — Factory-installed TriggerTech trigger breaks clean at 2.5 lbs with zero creep and a short overtravel. This matters because a crisp trigger is the single biggest upgrade for accuracy, and this one is competition-grade out of the box.
• Remington 700-Style Interface — The receiver uses a standard R700 footprint, so you can swap triggers, stocks, and chassis without gunsmithing. This matters because it opens up the aftermarket for customization and repairs.
• Adjustable Length of Pull — The stock adjusts from 13 to 14.5 inches via spacers and a buttpad swap. This matters because a proper fit reduces flinch and improves repeatability, especially under match pressure.

Who It’s For

This rifle is built for the competition shooter who wants a rimfire trainer that mimics a centerfire precision rig, but also needs something light enough for small-game fieldwork. If you shoot NRL22, PRS Rimfire, or just want a .22 WMR that can reach out to 200 yards with confidence, the MPR Rimfire fits. It also appeals to the hunter who wants a folding rifle for packing into backcountry spots.

Pros & Cons

• Pro: Carbon fiber barrel keeps weight down to 6.9 lbs without sacrificing stiffness.
• Pro: Folding stock makes it easy to store in a backpack or truck gun case.
• Pro: TriggerTech trigger is a major upgrade over factory rimfire triggers.
• Con: The folding stock adds a bit of wobble if the latch isn’t fully engaged—check it before each stage.
• Con: .22 WMR ammo can be harder to find than .22 LR, especially match-grade loads.

FAQ

What is the barrel twist rate on the Christensen Arms MPR Rimfire .22 WMR?

Per Christensen Arms specs, the 16-inch barrel has a 1:16 twist rate, optimized for 40- to 50-grain .22 WMR bullets.

Can I use a suppressor with this rifle?

Yes, the barrel is threaded 1/2×28 at the muzzle and comes with a thread protector. A suppressor adds length but the folding stock still works with most cans under 2 inches in diameter.

Does the folding stock lock in both open and closed positions?

Yes, the stock locks securely when folded and when extended. The latch is positive and audible, but give it a firm tug before each stage to ensure it’s fully seated.

What scope base does it use?

It uses a Remington 700 short-action footprint, so any R700-compatible scope base or one-piece mount will fit. I recommend a 20 MOA base for long-range rimfire.
