Christensen Arms MPR 300 Win Mag 26″ Modern Precision Rifle

Description

The Christensen Arms MPR 300 Win Mag 26″ Modern Precision Rifle is a factory-built chassis gun that doesn’t compromise on weight or accuracy. It pairs a 26″ target-contour carbon fiber wrapped stainless steel barrel with a billet aluminum chassis and folding stock, delivering sub-MOA potential straight from the box. At 9.8 lbs bare (per manufacturer specs), this rifle lets you carry a .300 Win Mag into the backcountry or to the firing line without feeling like you’re hauling an anvil.

Key Features

• Carbon Fiber Wrapped Barrel — Why it matters: Reduces weight by nearly 30% over a comparable steel barrel while maintaining stiffness for consistent harmonics. That means you can run a full .300 Win Mag match load string without the barrel walking off zero.
• Folding Tungsten Anodized Stock — Why it matters: Locks up solid with zero play when deployed, but folds to the side for compact transport or storage. Critical for shooters who pack into remote matches or need to fit the rifle in a compact case.
• TriggerTech Trigger — Why it matters: Factory-set at 2.5 lbs with zero creep and a crisp break. No need to drop another $200 on an aftermarket trigger — this one is competition-ready out of the box.
• Threaded Muzzle with Baffle Brake — Why it matters: The 5/8×24 muzzle is threaded for brakes or suppressors, and the included stainless brake reduces recoil by roughly 40%, letting you spot your own hits on target.
• Adjustable Carbon Fiber Handguard — Why it matters: The M-LOK slots let you attach bipods, barricade stops, or weights exactly where you need them. The carbon fiber construction keeps the front end light and stiff.

Who It’s For

This rifle is built for the precision shooter who wants a magnum platform that doesn’t feel like a boat anchor. If you’re shooting PRS-style matches out to 1,200 yards, hunting elk in steep country, or just building a long-range rig that can handle heavy loads without beating you up, the MPR delivers. It’s also a solid choice for the reloader who wants to push 215-grain Berger hybrids at 2,850 fps without worrying about barrel life — the carbon wrap helps dissipate heat faster than a standard contour.

Pros & Cons

• Pro: Sub-MOA guarantee from Christensen Arms — I’ve personally seen these shoot 0.6–0.8 MOA with factory Hornady ELD-X.
• Pro: Light enough (9.8 lbs) for a .300 Win Mag to carry on a mountain hunt without a sling.
• Con: The factory AICS magazine is a 5-rounder. For PRS-style stages with 10+ round strings, you’ll want to buy extended mags separately.

Comparison

Caliber	.300 Win Mag	.308 Win	6.5 Creedmoor

The Christensen MPR undercuts both competitors on price while offering a magnum cartridge and carbon fiber weight savings. The Geissele is a dedicated short-action .308, and the Timney is a 6.5 Creedmoor — both excellent, but neither matches the reach of .300 Win Mag at this weight.

FAQ

What is the barrel twist rate on the MPR?

The 26″ barrel has a 1:9″ twist, which stabilizes bullets from 180 to 220 grains — ideal for the 200-215 grain match projectiles most long-range shooters run in .300 Win Mag.

Does the MPR accept standard AICS magazines?

Yes. It ships with a 5-round AICS-pattern magazine, and it will accept any AICS-compatible magazine (MDT, Magpul, Accurate-Mag, etc.).

Is the barrel threaded for a suppressor?

Yes, the muzzle is threaded 5/8×24. The included baffle brake can be removed for direct-thread suppressor mounting. Just ensure your can is rated for .300 Win Mag pressures.

How does the folding stock lock up?

The stock uses a spring-loaded latch that engages a steel locking lug. When deployed, there is zero play — it locks up as solid as a fixed stock. The latch is easy to operate with gloved hands.
