Christensen Arms MPR Rimfire .22 Magnum 16" Black/Tan Rifle - Model 8011202400

The Christensen Arms MPR Rimfire is a modern precision .22 Magnum rifle that brings chassis-rifle sophistication to rimfire shooting. Built around a Remington 700-style action with a precision-machined aluminum receiver, this 16-inch rifle combines carbon fiber construction, M-LOK modularity, and a folding stock to create a compact, packable platform suited to range plinking, small-game hunting, competition shooting, or backcountry fun. At home in a daypack or slung over your shoulder, the MPR Rimfire doesn't compromise on accuracy or ergonomics.

The heart of this rimfire is a Christensen Arms carbon fiber tension barrel, precision-lapped and button-rifled with a match chamber and 1/2x28 threaded muzzle. That tension-barrel design, paired with a TriggerTech trigger and 0-MOA optic rail, delivers the kind of shot-to-shot consistency you'd expect from a precision rifle—but in a caliber that's fun to shoot and easy on the wallet. A Ruger BX-1 magazine keeps feeding simple and reliable.

The chassis platform is where the MPR Rimfire truly shines for serious rimfire enthusiasts. A 7075 aluminum billet chassis accepts either a 10.5- or 14-inch FFT carbon fiber handguard with M-LOK slots, so you can attach lights, bipods, and other accessories. Six QD flush-cup mounts provide quick attachment options, and an adjustable FFT carbon fiber cheek riser helps you dial in your sight picture. Length of pull adjusts from 12.5 to 14.5 inches, the folding stock locks via MagneLink technology and actually collapses for transport or storage, and a monopod Picatinny mount is built in. V-block bedding ensures consistent barrel harmonics, and an AR-compatible grip rounds out a rifle designed for shooters who want real versatility in a lightweight package.

This is a rimfire for people who refuse to compromise—whether you're zeroing a new optic on the cheap, running a rimfire precision match, or reaching out to surprising distances with quality ammunition.

Frequently Asked Questions

Can I use this rifle with a suppressor?

Yes. The MPR Rimfire comes with a 1/2x28 threaded muzzle, which is the standard rimfire suppressor thread pitch, making it suppressor-ready out of the box.

What magazine does the MPR Rimfire .22 Magnum use?

The rifle ships with a Ruger BX-1 magazine for reliable feeding and simple maintenance.

How adjustable is the stock and cheek riser?

Length of pull adjusts from 12.5 to 14.5 inches to fit different shooter body types and shooting positions. The FFT carbon fiber cheek riser is also adjustable to help you dial in your sight picture over your scope or red dot.

Does the stock actually fold, and will it fit in a backpack?

Yes. The stock folds and locks via MagneLink technology, and the 16-inch barrel combined with the folding design makes the rifle compact enough to pack into a rucksack or daypack for backcountry or remote-area shooting.

What handguard length should I choose?

The FFT carbon fiber handguard is available in 10.5-inch or 14-inch lengths. The 10.5-inch option provides a more compact package, while the 14-inch offers more real estate for mounting accessories via M-LOK. Both are included in the rifle; check your specific model to confirm which you have.
