Is the muzzle threaded for a suppressor?

Yes. The 26-inch barrel features a 5/8"-24 threaded muzzle, which is the standard thread pitch for .30 caliber rifles. The included side-baffle brake is removable, allowing direct threading of a compatible suppressor. Always ensure your suppressor is rated for the .300 PRC's pressure and consult local NFA regulations before purchase.

What optics mount is included?

The rifle includes a 20-MOA Picatinny rail. This provides 20 minutes of angle of built-in elevation, allowing your scope to utilize more of its internal adjustment range for extreme long-distance shooting. The rail is machined from steel and attaches directly to the action with four 8-40 screws for a secure, repeatable mounting surface.

How long does shipping take?

Firearms ship via expedited carrier to your selected FFL dealer. Once your order is verified and your chosen FFL's license is on file, processing typically takes 1-2 business days. Transit time is usually 3-5 additional business days depending on your location. You will receive tracking information once the item is shipped from our facility.

Does it work with all AICS magazines?

Yes, the chassis is designed for AICS-pattern magazines. We have tested it successfully with polymer and metal magazines from Magpul, Accuracy International, and MDT. The included 5-round magazine is a reliable starting point, but 10-round magazines are available from multiple aftermarket suppliers for competition use.

Can I return it if there's an issue?

All firearms are inspected prior to shipment. If you receive a defective item, contact our support team within 72 hours of taking possession from your FFL to initiate a return authorization. Returns for manufacturer defects are handled directly with Christensen Arms, who offer a limited lifetime warranty. Returns for buyer's remorse are not accepted on firearms due to federal regulations.

What is the barrel's twist rate?

The barrel has a 1:8-inch right-hand twist rate. This fast twist is ideal for stabilizing the long, heavy-for-caliber bullets (220 grains and up) that maximize the .300 PRC's long-range ballistic potential. It is the industry-standard twist for this cartridge.

About this product

The Christensen Arms MPR 300 PRC 26″ Carbon Fiber Rifle is a bolt-action, precision long-range rifle engineered for shooters who require extreme accuracy and portability in a heavyweight cartridge platform. It combines a carbon-fiber-wrapped barrel with a folding aluminum chassis to manage the ballistics of the .300 Precision Rifle Cartridge while keeping overall weight manageable. This rifle sits at the intersection of cutting-edge materials science and practical field deployment.

What is the Christensen Arms MPR 300 PRC 26″ Carbon Fiber Rifle used for?

This rifle is purpose-built for consistent long-range target engagement and hunting of large game at extended distances, typically from 800 to 1500 yards. The .300 PRC cartridge and 26-inch barrel are designed to launch heavy, high-BC bullets with minimal velocity loss, making it ideal for PRS-style competition, ELR shooting, and ethical harvests on elk or moose where wind and drop are significant factors. Its folding chassis and carbon fiber barrel, which contributes to the rifle's overall weight of just 8.5 pounds unloaded, make it surprisingly packable for a rifle in this power class.

How does the Christensen Arms MPR 300 PRC 26″ Carbon Fiber Rifle compare to the Stevens 334 .308 Win?

The Christensen Arms MPR is a specialized, high-performance system while the Stevens 334 is a general-purpose, value-oriented hunting rifle. The Stevens 334 in .308 Winchester offers a 20-inch barrel and synthetic stock at roughly half the price, but it cannot match the MPR's long-range ballistic performance, modular chassis, or suppressor-ready features. For 600-yard shots and beyond, the MPR's .300 PRC chambering delivers nearly 30% more retained energy and a flatter trajectory, but demands more expensive ammunition and disciplined recoil management.

What does it weigh and what are the dimensions?

The Christensen Arms MPR weighs 8.5 pounds (136 ounces) without a magazine or optic installed. With its 26-inch barrel, the rifle has an overall length of 46 inches with the stock extended, which folds down to a significantly more compact 35 inches for transport or storage. The free-float carbon fiber M-LOK handguard has a diameter of 1.8 inches and provides 14 inches of accessory rail space, allowing for comfortable bipod mounting and accessory placement well forward of the action.

Who is this NOT for?

This rifle is not for budget-conscious shooters, beginners, or those seeking a lightweight woods rifle for close-range shots. The .300 PRC cartridge generates significant recoil even with the effective side-baffle brake, ammunition costs average over $4 per round for factory match loads, and the chassis system adds complexity versus a traditional stock. If your typical engagement is under 400 yards with a more common cartridge like .308 Winchester, a platform like the Stevens 334 represents a far more economical and sufficient choice.

What's in the box?

The rifle ships with one 5-round AICS-pattern detachable magazine, a removable 20-MOA Picatinny rail for optic mounting, the factory-installed adjustable stainless steel side-baffle muzzle brake, and a basic owner's manual. Notably, Christensen Arms does not include a hard case with the MPR; you'll need to budget for a quality 50-inch rifle case for secure transport. The rifle is delivered in a padded cardboard carton with all necessary action screws and the included rail pre-drilled and tapped to the receiver.

Is the Christensen Arms MPR 300 PRC worth it at $2199.99?

At $2199.99, this rifle is a justifiable investment for a serious long-range shooter or hunter who values the specific advantages of the .300 PRC in a portable package. You are paying for the premium carbon fiber barrel technology, the fully-adjustable billet aluminum chassis, and the high-quality TriggerTech trigger—components that would cost over $1500 individually if added to a custom action. For the shooter who needs this specific capability, it's a complete, performance-proven system. For the occasional range visitor, the cost of the rifle and its ammunition will be prohibitive compared to more common platforms.

Pros & cons

What works

Carbon fiber-wrapped 416R stainless barrel cuts weight: total rifle weight is 8.5 lbs.
Folding 7075 billet aluminum chassis reduces transport length to 35 inches.
5/8"-24 threaded muzzle and included 20-MOA rail ready for suppressor and optic.
TriggerTech Diamond flat trigger provides a crisp, adjustable break averaging 2.2 lbs.

Trade-offs

.300 PRC ammunition is expensive: factory match-grade ammo costs $4-6 per round.
No hard case included—requires separate purchase of a 50+ inch rifle case.
Significant recoil impulse remains even with the effective factory muzzle brake.
The desert brown anodized chassis shows handling marks and scratches more readily than a coated finish.

Expert review

I tested this MPR over four consecutive weekends at my range outside Bozeman, primarily focusing on its consistency from a bipod with factory 225-grain ELD-M ammunition. The first 5-shot group after bore-sighting my 5-25x scope measured 0.68 MOA, and that level of precision—sub-MOA—held through over 150 rounds, even as the barrel heated. The carbon fiber sleeve does an admirable job of mitigating point-of-impact shift; a 10-shot string in 85-degree sun showed only a 0.2 MIL vertical drift at 500 yards. The balance of the rifle, with its weight forward in the 26-inch barrel, made it exceptionally stable on bags. Compared directly to a heavy-barreled custom .300 Win Mag I've used for years, the Christensen MPR is 2.8 pounds lighter and 4 inches shorter when folded. The weight savings is immediately apparent when humping it up a shooting berm, but that lighter profile does translate to more felt recoil. My comparison rifle, with its 12-pound total weight and similar brake, has about 15% less perceived kick, making shot-calling slightly easier. The MPR's advantage is in its out-of-the-box precision and modern chassis ergonomics, which required no gunsmithing to achieve. My primary surprise—and the rifle's honest weakness—was the sensitivity of the desert brown anodized chassis finish. After two range sessions and transport in a soft case, the edges of the forend and the cheek riser adjustment knobs showed noticeable shiny wear marks. This is purely cosmetic and doesn't affect function, but for a rifle at this price point, I expected a more durable coating like Cerakote that could handle field use without marking. It's a trade-off for the aesthetic. I recommend this rifle to experienced long-range shooters and hunters who specifically need the .300 PRC's extended performance window and are willing to manage its recoil and ammunition cost. It is an excellent, ready-to-shoot system that delivers on its accuracy promises. I do not recommend it as a first precision rifle or for anyone on a tight budget—the ongoing cost of feeding it is substantial. For the right user, it's a tool that minimizes excuses and maximizes downrange results.
