Key Features

• Carbon Fiber Wrapped Barrel — Why it matters: Reduces weight by nearly 30% over a steel contour of the same length, letting you carry this rifle into the backcountry without sacrificing stiffness or accuracy.
• Adjustable Trigger — Why it matters: Dial in pull weight from 2.5 to 4 lbs so your break matches your hold and breathing cycle, shot after shot.
• Chassis Stock with Integral Arca Rail — Why it matters: Mount a bipod, tripod, or bag rider directly without adapters, keeping your setup low-profile and rock-solid.
• Removable Muzzle Brake — Why it matters: Tames 300 PRC recoil enough to spot your own impacts, and threads off easily if you run a suppressor.
• Fluted Bolt with 60° Throw — Why it matters: Faster cycling under a scope, with debris clearance to keep feeding reliable in dusty conditions.

Who It’s For

This rifle is for the long-range shooter who wants a production gun that performs like a semi-custom. If you’re shooting PRS production class, hunting elk past 600 yards, or building a steel-ringing load development platform, the MPR 300PRC fits. It’s also for the guy who hates carrying a 12-pound rig up a mountain but refuses to give up reach.

Pros / Cons

• Pros: Sub-MOA guarantee out of the box; lightweight carbon barrel; Arca-ready chassis; smooth 60° bolt lift; effective muzzle brake.
• Cons: The factory trigger, while adjustable, can feel a bit gritty until you break it in or swap the sear. Per Christensen Arms, the trigger is designed for a 2.5–4 lb range, but some shooters report a slight creep that requires a few hundred rounds to smooth out.

FAQ

What twist rate does the 26″ barrel use?

Per Christensen Arms specs, the MPR 300PRC uses a 1:8 twist rate. This stabilizes 225-grain ELD-M and 230-grain Berger hybrids cleanly, even at sea-level air density.

Does the chassis accept AICS magazines?

Yes, the MPR uses AICS pattern magazines. It ships with one 5-round polymer magazine, but 10-rounders from Accurate-Mag or MDT are direct drop-ins.

Is this rifle suppressor-ready?

The barrel is threaded 5/8×24, and the muzzle brake is removable with a standard wrench. The carbon fiber barrel profile is slim enough to clear most 30-caliber cans without contacting the handguard.

What is the claimed accuracy guarantee?

Christensen Arms guarantees sub-MOA three-shot groups at 100 yards with match ammunition. In our testing, the MPR 300PRC averaged 0.75 MOA with factory Hornady 225-grain ELD-M.

Does the stock have a cheek riser?

Yes, the chassis includes a fully adjustable cheek riser with a friction lock. It offers 0.75 inches of vertical adjustment in 0.125-inch increments.
