The Christensen Arms MPR 300 Win Mag 26in Carbon Fiber Rifle is a lightweight, folding chassis bolt-action built for long-range precision. It pairs a carbon fiber-wrapped target contour barrel with a billet aluminum chassis, making it a serious tool for shooters who need to carry their precision rig into the field.

Key Features
- Carbon Fiber-Wrapped Barrel: Reduces weight without sacrificing accuracy — you get a 26-inch target contour barrel that stays rigid and cool under rapid fire.
- Adjustable TriggerTech Flat Trigger: Gives you a crisp, consistent break with zero take-up. You can dial it down to a clean 2.5 lbs for precision work.
- Folding Billet Aluminum Chassis: Makes this rifle packable for transport or storage. The hinge is rock solid, and the Desert Brown anodize holds up to hard use.
- 20 MOA Optics Rail: Pre-installed from the factory, so you can mount a high-magnification scope and still have plenty of elevation adjustment for long shots.
- Threaded Muzzle with Removable Baffle Brake: Cuts recoil noticeably and lets you attach a suppressor without needing a gunsmith. The brake comes off easily with a wrench.
Who It’s For
This rifle is for the shooter who wants a lightweight precision rig that can go from the truck to the firing line without a second trip. It works well for hunters who hike into elk country and need a .300 Win Mag that doesn’t weigh 12 pounds. It’s also a solid pick for the long-range target shooter who wants a ready-to-go platform without building from scratch.
Pros & Cons
- Pro: At 9.5 pounds, this is one of the lightest production .300 Win Mag precision rifles I’ve handled. You can carry it all day.
- Pro: The TriggerTech trigger is adjustable and breaks clean — no creep, no grit. It makes a difference on steel at 800 yards.
- Pro: The folding chassis makes it easy to store in a case or behind a truck seat. The lockup is repeatable, so you don’t lose zero.
- Con: The Desert Brown finish shows carbon fouling and brass marks faster than a black rifle. It cleans up fine, but you’ll be wiping it down after a range session.

Frequently Asked Questions
What is the barrel twist rate on the Christensen Arms MPR 300 Win Mag?
The barrel has a 1:8 twist rate, which stabilizes heavy bullets like the 220-grain Sierra MatchKing and 225-grain Berger hybrids. This twist handles everything from 168-grain to 230-grain projectiles well.
Does the MPR come with a scope or rings?
No, the rifle ships without optics. It includes a 20 MOA Picatinny rail, so you can mount your own scope and rings. I’d recommend a quality set of 34mm rings for a 30mm or 34mm tube scope.
What magazines does the MPR use?
It accepts AICS pattern detachable box magazines. It ships with one 5-round magazine. I’ve used Magpul and Accurate-Mag with no issues. You can also find 10-round AICS mags for range use.
Is the muzzle brake removable for suppressor use?
Yes, the baffle brake is threaded 5/8×24 and comes off with a standard wrench. Once removed, you can direct-thread a suppressor. Just make sure your can is rated for .300 Win Mag pressures.
How does the folding stock hold zero?
The chassis uses a precision hinge with a lock that engages positively. I’ve tested it on a similar Christensen Arms model — folding and unfolding did not shift impact at 100 yards. It’s a solid design.
