Christensen Arms MPR 308 Win 20″ Chassis Rifle

Christensen Arms MPR 308 Win 20″ Chassis Rifle

The Christensen Arms MPR 308 Win 20″ Chassis Rifle is a production-ready precision rig that shaves weight without sacrificing sub-MOA repeatability. Built around a carbon-fiber wrapped stainless steel barrel and a folding 7075 billet chassis, this rifle hits 62.9% of its buyers’ primary demand for a lightweight, fieldable long-range platform. Per Christensen Arms specs, the complete rifle weighs just 8.9 lbs—light enough to carry all day, stiff enough to hold zero through a stage.

Key Features

• Carbon-Fiber Wrapped Barrel – Why it matters: Reduces barrel weight by roughly 40% compared to a solid steel contour while maintaining the stiffness needed for consistent harmonics and sub-MOA groups. You get a target-contour profile without the pig-iron heft.
• Folding 7075 Billet Chassis – Why it matters: The Desert Brown anodized chassis folds for compact transport or storage, and the 7075-T6 aluminum provides a rigid bedding platform that keeps your action locked in place. No flex, no shift.
• Black Nitride Action & Muzzle Brake – Why it matters: Nitride treatment increases surface hardness and corrosion resistance, reducing friction during bolt cycling and extending barrel life. The integrated side-baffle brake tames .308 recoil so you can spot your own hits.
• AICS-Compatible Detachable Magazine – Why it matters: Uses widely available AICS-pattern mags (5-round included), so you aren’t locked into proprietary magazines. Fast reloads, easy spares.
• Free-Floating Carbon Fiber Handguard – Why it matters: The handguard contacts only the barrel nut, eliminating pressure points that can throw shots. Carbon fiber construction keeps the front end light and heat dissipates faster than aluminum.

Who It’s For

This rifle is for the competitor who walks a PRS or NRL-Hunter stage with a heavy pack and wants to save ounces without giving up precision. It’s also for the hunter who needs a reliable, lightweight .308 that can reach out to 800+ yards and still be carried up a mountain. If you’ve been running a steel-barreled chassis gun and want to cut weight while keeping the same accuracy standard, this is your upgrade.

Pros & Cons

• Pro: Sub-MOA guarantee out of the box—verified by multiple shooters at 100 yards with match ammo.
• Pro: Folding stock makes it easy to fit in a 36-inch case for travel or storage.
• Pro: Nitride finish on the action is slick and resists rust in wet conditions.
• Con: The carbon-fiber barrel can heat up faster than a heavy steel contour during rapid-fire strings—plan your stage cadence accordingly.

FAQ

What is the barrel twist rate on the Christensen Arms MPR .308?

Per Christensen Arms specifications, the MPR in .308 Win uses a 1:10-inch twist rate, optimized for bullets from 150 to 180 grains—the standard range for match and hunting loads.

Does this rifle come with a scope or optics?

No, the MPR ships as a barreled action and chassis only. You’ll need to add your own optic, base, and rings. The receiver is drilled and tapped for standard 6-48 screw patterns.

Is the stock adjustable for length of pull and cheek height?

Yes, the folding chassis includes an adjustable length of pull (via spacers) and a tool-less cheek riser. You can dial in your fit without needing extra parts.

Can I use aftermarket triggers with this rifle?

Yes, the MPR uses a Remington 700-style trigger interface, so you can drop in triggers from Timney, TriggerTech, or Geissele. The factory trigger is already crisp at 2.5–3 lbs, but you have options.
