The Christensen Arms Modern Carbon Rifle in 300 PRC delivers lightweight precision and superior accuracy for long-range hunters and precision shooters demanding elite performance.
Experience the future of long-range precision shooting with the Christensen Arms MCR .300 PRC—a semi-automatic rifle that brings magnum cartridge performance to the AR platform without the weight penalty. At just 8.5 lbs, this is the only production semi-auto rifle chambered in .300 PRC, combining a 24″ carbon fiber-wrapped barrel with an adjustable carbon fiber stock to deliver 1,500+ yard capability in a fast-handling, self-loading platform. Whether you’re pursuing extended-range hunting, competition shooting, or precision rifle applications, the MCR .300 PRC redefines what’s possible in a modern semi-automatic magnum rifle.
About Christensen Arms
Since 1995, Christensen Arms has engineered ultra-lightweight precision rifles in Gunnison, Utah by pioneering carbon fiber-wrapped barrel technology. Their signature construction wraps aerospace-grade carbon fiber around a stainless steel barrel core, reducing rifle weight to levels impossible with traditional steel barrels while maintaining the rigidity and thermal stability required for sub-MOA accuracy. Christensen rifles are built for shooters who refuse to compromise: lighter rigs, harder hits, and precision that travels.
The MCR (Multi-Caliber Rifle) is Christensen Arms’ boldest engineering achievement: a semi-automatic AR-10 platform scaled for magnum PRC cartridges without ballistic compromise or unwieldy weight. The .300 PRC is a modern long-range round—designed from the ground up for 190+ grain match-grade bullets at high velocity and extreme distance. With a 24″ barrel, you unlock the full velocity and energy envelope the cartridge promises, enabling consistent, ethical shots well beyond 1,000 yards on elk, moose, and large game. The gas-operated action cycles reliably with heavy ammunition, while the 5-round AICS-compatible magazine pairs with proven supply chains for ammunition and accessories.
Built for shooters serious about precision, the MCR .300 PRC excels in multiple roles: extended-range hunting where wind and distance demand a magnum cartridge, precision rifle competitions at 1,000+ yards, and long-range training where semi-automatic convenience meets bolt-action accuracy. The carbon fiber furniture—barrel, stock, and handguard—keeps total weight manageable for mountain hunts and day-long field work, while the AR platform ergonomics and controls remain familiar to modern rifle shooters. This is not a compromise rifle; it’s a purpose-built tool for precision at distance.

Frequently Asked Questions
Q: What is .300 PRC and why choose it over .300 Win Mag or .338 Lapua?
A: .300 PRC (Precision Rifle Cartridge) is a modern magnum designed for high-velocity, heavy-bullet performance at extreme range. Compared to .300 Win Mag, it delivers superior ballistics in the 2,800+ yard range while maintaining flatter trajectory and less wind drift. Versus .338 Lapua, .300 PRC offers lighter recoil, lower ammunition cost, and sufficient power for most long-range hunting. It’s the caliber choice for precision shooters prioritizing accuracy and velocity in a manageable platform.
Q: Why is the MCR .300 PRC only 8.5 lbs when other semi-auto rifles weigh 10+ lbs?
A: Christensen Arms’ carbon fiber-wrapped barrel technology reduces weight without sacrificing rigidity or accuracy. By wrapping aerospace-grade carbon fiber around a stainless steel core, the barrel itself weighs significantly less than a traditional steel barrel, while the carbon fiber stock and handguard further minimize overall mass. This construction maintains the thermal stability and precision required for consistent long-range accuracy.
Q: How does carbon fiber barrel construction improve rifle performance?
A: Carbon fiber wrapping reduces barrel weight and heat retention, allowing cooler, faster shooting sessions without thermal mirage affecting accuracy. The stainless steel core maintains the rigidity and hardness needed for precision, while carbon fiber’s low thermal conductivity reduces temperature fluctuations that cause point-of-impact shifts. Result: lighter rifle, faster target acquisition, and more consistent accuracy downrange.
Q: Is the MCR .300 PRC suitable for hunting, competition, or both?
A: The MCR .300 PRC excels in both roles. For hunting, its 24″ barrel maximizes .300 PRC velocity for ethical long-range shots on elk, moose, and large game; the semi-automatic action provides follow-up capability, and 8.5 lbs allows all-day field carry. For competition, its precision engineering, AICS-compatible magazine, and AR-platform familiarity suit 1,000+ yard precision rifle matches. Its versatility makes it ideal for serious shooters who demand one rifle for multiple long-range disciplines.
