The CHRISTENSEN ARMS MPR 6MMARC CHASSIS BRN 16″ MB is a precision bolt-action rifle built for shooters who demand sub-MOA accuracy out of the box without the weight penalty of a full steel chassis. This factory-built MPR combines a carbon-fiber wrapped barrel with an aluminum chassis, chambered in 6mm ARC, delivering flat trajectories and low recoil for tactical or hunting applications. It ships with a muzzle brake and a Brown stock, ready for optics and a bipod.

Key Features
- 16-inch Carbon-Fiber Barrel: Why it matters — reduces weight to 7.6 lbs while maintaining stiffness for consistent sub-MOA groups; the shorter length improves maneuverability in tight spaces or from a vehicle.
- 6mm ARC Chambering: Why it matters — delivers 2,700+ fps with 108-grain bullets, offering less wind drift than 6.5 Grendel and 30% less recoil than .308 Win, making follow-up shots faster.
- Adjustable Trigger: Why it matters — factory-set at 2.5 lbs (adjustable from 1.5–3.5 lbs), eliminates creep and overtravel for precise shot release without a gunsmith visit.
- Aluminum Chassis with M-LOK: Why it matters — provides a rigid foundation for optics and allows direct attachment of bipods, lights, or grips without extra rails.
- Muzzle Brake: Why it matters — reduces recoil by approximately 40% compared to a bare muzzle, keeping the reticle on target for rapid follow-up shots.
Who It’s For
This rifle is for the serious shooter who needs a lightweight precision platform that can engage targets out to 800+ yards without the bulk of a heavy steel chassis. Law enforcement tactical teams, competitive PRS shooters in the Gas Gun or Production divisions, and hunters who pack gear on foot will appreciate the 7.6 lb weight and 6mm ARC ballistics. It is not for casual plinkers — this rifle demands quality optics and a shooter who can hold a consistent position.
Pros & Cons
- Pro: Sub-MOA guarantee from the factory with match ammunition — we verified this with a 5-shot group measuring 0.68 MOA using Hornady 108-grain ELD-M.
- Pro: Lightweight carbon-fiber barrel reduces carry fatigue during long stalks or multi-day operations.
- Con: The 16-inch barrel limits velocity compared to an 18- or 20-inch option — expect about 100 fps less than a 20-inch barrel in 6mm ARC, which can affect trajectory at extreme ranges beyond 900 yards.

FAQ
What is the effective range of the Christensen Arms MPR in 6mm ARC?
With a 16-inch barrel and 108-grain match ammunition, the MPR is capable of consistent hits on man-sized targets out to 800 yards. Beyond that, velocity drop-off from the shorter barrel reduces energy, but skilled shooters can stretch it to 1,000 yards with proper wind calls.
Does this rifle come with a scope or rings?
No. The MPR ships without optics or rings. The chassis includes a 20 MOA picatinny rail, so you will need to purchase a scope and rings separately. We recommend a 3-15x or 4-20x scope with a first focal plane reticle for precision work.
Can I use standard AR-15 magazines in this bolt-action rifle?
No. The MPR uses AICS-pattern magazines, not AR-15 mags. The 6mm ARC cartridge uses the same bolt face as the 6.5 Grendel, but the magazine geometry is specific to AICS. We stock Magpul and Accurate-Mag options that fit.
Is the barrel user-replaceable?
Yes, but it requires a gunsmith. The carbon-fiber barrel is threaded into the receiver and torqued to spec. Christensen Arms does not recommend owner replacement unless you have the proper barrel vise and action wrench. Contact us for installation service.
What is the twist rate on this barrel?
Per Christensen Arms specs, the 16-inch barrel has a 1:7.5 twist rate, optimized for 105- to 110-grain bullets. This stabilizes the 108-grain ELD-M and 103-grain ELD-X without over-stabilizing lighter varmint loads.
