Christensen Arms MPR 300 Win Mag 26in Carbon Fiber Rifle

About this product

The Christensen Arms MPR 300 Win Mag 26in Carbon Fiber Rifle is a chassis-based long-range precision bolt-action built on a carbon-wrapped barrel and billet aluminum chassis. This rifle represents the integration of aerospace-weight reduction with the demands of sustained positional shooting beyond 1000 yards. Its specification sheet directly addresses the friction points of backcountry hunting and PRS-style competition—barrel heat, platform weight, and operational adaptability in cold or wet environments.

What is the Christensen Arms MPR 300 Win Mag used for?

The Christensen Arms MPR is built for extended-range precision engagements, primarily suited for PRS/NRL competition and backcountry hunting of large game like elk or moose. Its 26-inch carbon-wrapped barrel and .300 Winchester Magnum chambering provide the velocity and ballistic stability needed for consistent hits from 800 to 1200+ yards. The folding chassis and modular handguard accept suppressors, tripods, and night vision bridges, making it adaptable for both daylight matches and extended low-light work under a qualified training program.

How does the Christensen Arms MPR compare to the Stevens 334 Rifle?

The Christensen Arms MPR is a purpose-built precision system, while the Stevens 334 in .308 Win is a utilitarian hunting rifle. The Christensen MPR outperforms the Stevens 334 in sustained fire accuracy and modularity, featuring a carbon-wrapped barrel that stays 40-50°F cooler than a traditional steel barrel of the same contour after a 10-round string. The Stevens 334 holds a decisive advantage in cost, weighing in at roughly one-third the price, making it the logical choice for a basic, sub-500-yard deer rifle where the investment in advanced materials isn't justified.

What does it weigh and what are the dimensions?

Unloaded with its 5-round AICS magazine inserted, the rifle weighs 9.8 lbs. This weight is distributed over a 46.5-inch overall length when the stock is extended, which collapses down to 34 inches when folded for transport. The 26-inch barrel has a 1:10" twist rate, stabilizing heavy .300 WM projectiles between 180 and 230 grains for optimal long-range ballistics. This specific configuration balances weight reduction against the 72.6 ft-lbs of free recoil energy generated by a standard 180-grain load.

Who is this NOT for?

This rifle is not for shooters seeking a low-cost, general-purpose hunting tool or those new to high-recoil, magnum cartridges. The .300 Winchester Magnum chambering, coupled with a chassis designed for positional shooting, creates a platform that is punishing to learn on and over-specified for shots inside 300 yards. If your primary use is whitetail hunting from a box blind, consider a softer-shooting, lighter rifle like a Stevens 334 in .243 Win. Furthermore, the proprietary magazine system requires AICS-pattern magazines, adding to the long-term accessory cost.

What's in the box?

You receive the complete rifle, one 5-round AICS-compatible steel magazine, and the standard Christensen Arms hard case. The rifle ships with the removable stainless-steel side-baffle brake installed, which requires a 5/8"-24 wrench for removal if you plan to mount a suppressor. Notably, the box does not include spare action screws, additional M-LOK hardware, or a torque wrench for the 20 MOA optics rail—tools you will need to properly mount a scope and accessories. Plan for an additional $120-$200 in necessary mounting hardware beyond the optic itself.

Is the Christensen Arms MPR worth it at $2199.99?

At this price point, the Christensen Arms MPR justifies its cost through material technology and chassis rigidity that directly impacts long-range consistency. The investment buys you a system with a carbon-wrapped barrel that mitigates point-of-impact shift during long strings of fire and a folding stock that allows for discreet transport in a 34-inch case. For the shooter who demands repeatable sub-MOA performance with magnum cartridges and needs to hike miles into position, this rifle's 9.8 lb weight and thermal stability are worth the premium over a $700 conventional rifle that may not hold zero under the same conditions.
