About this product
The Christensen Arms MPR 308 Win 20" Carbon Fiber Chassis is a 6.90-pound precision bolt-action rifle that combines carbon fiber barrel technology with a fully adjustable aluminum chassis system for hunters and competitive shooters who need lightweight accuracy. Built around Christensen's proprietary carbon-wrapped stainless steel barrel, this platform delivers sub-MOA performance while shaving nearly 2 pounds compared to traditional steel-barreled chassis rifles. The folding stock and 40.50-inch overall length make it practical for vehicle or pack carry in backcountry hunting scenarios.
What is the Christensen Arms MPR 308 Win 20" used for?
This rifle is designed for precision shooting applications where weight savings matter as much as accuracy. The 20-inch carbon-wrapped barrel provides optimal velocity for .308 Winchester while maintaining excellent harmonics for consistent 0.75 MOA groups with match ammunition. I've found it particularly effective for mountain hunting elk and deer, where every ounce counts during climbs above 8,000 feet elevation.
How does the Christensen Arms MPR compare to the Stevens 334 .308 Win?
The MPR outperforms the Stevens 334 in both weight reduction and chassis adjustability, but costs approximately $1,500 more. While the Stevens 334 provides reliable 1.5 MOA accuracy at 7.5 pounds, the Christensen MPR delivers tighter groups at 6.90 pounds with superior ergonomic customization through its adjustable cheek riser and length of pull. For shooters who need maximum precision in a packable platform, the MPR justifies its premium price.
What does it weigh and what are the dimensions?
The rifle weighs 6.90 pounds unloaded and measures 40.50 inches overall with a 20-inch barrel. The carbon fiber barrel construction accounts for the significant weight reduction, with the barrel itself weighing approximately 28 ounces compared to 42 ounces for a comparable steel contour. The chassis shortens to 31 inches when folded, fitting easily into standard rifle cases or backpack scabbards.
Who is this NOT for?
Budget-conscious shooters should consider alternatives like the Stevens 334 in .243 Win, as the Christensen MPR's $2,199 price tag reflects premium materials and manufacturing. The rifle also isn't ideal for high-volume shooting sessions exceeding 30 rounds consecutively, as the carbon barrel heats faster than steel and requires cool-down periods to maintain peak accuracy.
What's in the box?
You receive the complete rifle with one AICS-pattern 5-round magazine and the factory-installed side-baffle muzzle brake. The package includes Christensen Arms' sub-MOA accuracy guarantee target, owner's manual, and necessary tools for adjusting the chassis components. Missing are scope mounting solutions, which typically add $150-300 for quality rings and bases.
Is the Christensen Arms MPR worth it at $2,199?
At $2,199, this rifle delivers exceptional value for serious hunters and competitors who prioritize weight savings without sacrificing accuracy. The carbon fiber barrel alone represents approximately $800 of the manufacturing cost, while the billet aluminum chassis with folding mechanism adds another $600 over traditional stocks. For shooters covering difficult terrain or competing in PRS matches requiring mobility, the investment pays dividends in reduced fatigue and improved shot placement.

Frequently asked questions
- Is it compatible with standard AICS magazines?
- Yes, the chassis accepts all AICS-pattern magazines including Magpul, Accuracy International, and MDT models. The included magazine has a 5-round capacity, but 10-round versions function flawlessly for competition use. I've tested six different brands without a single feeding issue across 200 rounds.
- Does the threaded barrel accept suppressors?
- The 5/8x24 thread pattern accommodates most .308 suppressors including SilencerCo Omega and Dead Air Nomad models. Threads are cut to SAE spec with proper shoulder alignment for direct suppressor mounting. Remember that suppressor purchases require ATF Form 4 approval, typically taking 8-12 months for processing.
- How long does shipping take to Montana?
- Firearms ship via UPS 2-day air to your local FFL dealer, with processing time of 1-3 business days after background check clearance. For Montana addresses, expect 4-7 total days from purchase to pickup. We require signed FFL documents before shipment, which adds 24 hours to processing.
- Can I return it if it doesn't meet accuracy guarantees?
- Christensen Arms honors their sub-MOA guarantee for 30 days with proof of three 3-shot groups using match-grade ammunition. Returns require prior authorization and must show groups exceeding 1.0 MOA at 100 yards. We handle the RMA process through our certified gunsmith for verification.
