Description
The Christensen Arms MPR 308WIN Chassis BLK 20″ MB is a production-ready precision rifle that delivers sub-MOA accuracy straight from the box. Built on a lightweight carbon-fiber wrapped barrel and a rigid aluminum chassis, this .308 Win bolt action is designed for shooters who demand repeatable precision at distance without the weight penalty of a full steel rig. At $2199.99, it undercuts many custom builds while matching their performance.

Key Features
- Carbon-Fiber Wrapped Barrel – Why it matters: Reduces barrel weight by 30% over steel while maintaining stiffness for consistent harmonics. According to Christensen Arms specs, this barrel profile holds sub-MOA groups with match ammo.
- Adjustable Trigger – Why it matters: Factory trigger breaks at 2.5–3.5 lbs, letting you dial in the pull weight for your preferred competition or precision load without swapping parts.
- Full Aluminum Chassis – Why it matters: The rigid 7075-T6 chassis provides a stable platform for the action and barrel, minimizing flex and improving consistency from shot to shot.
- 20″ Barrel with Muzzle Brake – Why it matters: The 20-inch length balances velocity and maneuverability; the integral brake cuts felt recoil by up to 40%, letting you spot impacts faster.
- Detachable Box Magazine – Why it matters: Accepts AICS-pattern magazines (10-round included), so you can load and reload quickly during stages or range sessions.
Who It’s For
This rifle is built for competition shooters who shoot PRS, NRL Hunter, or tactical matches where weight and accuracy matter. It also fits precision hunters who want a lightweight rig for mountain positions. If you’re a reloader chasing single-digit SDs, the carbon barrel handles heat strings well.
Pros & Cons
Pros: Sub-MOA guarantee out of the box; light weight (8.2 lbs) for a chassis rifle; adjustable trigger; reliable with factory and handloads; muzzle brake is effective without being deafening.
Cons: The carbon barrel can heat up faster than a heavy steel barrel during rapid-fire strings (e.g., 20 rounds in 2 minutes). For extreme long-range benchrest, a heavier barrel might hold tighter groups over long strings.

FAQ
What is the barrel twist rate on the Christensen Arms MPR .308?
The 20″ barrel has a 1:10 twist rate, optimized for 147–175 grain .308 bullets. It stabilizes match loads like Federal Gold Medal 168gr and 175gr SMK well.
Does the MPR come with a scope base?
Yes, the receiver has a 20 MOA Picatinny rail installed, ready for your scope rings or mount. No need to buy a separate base.
Can I use this rifle for hunting?
Absolutely. At 8.2 lbs with a 20″ barrel, it’s light enough for backcountry hunting, but the chassis makes it more suited for long-range hunting (300+ yards) than close-cover brush hunting.
Is the muzzle brake removable?
Yes, the brake is threaded onto the barrel (5/8×24 thread pattern). You can remove it and run a suppressor if you prefer, but check local laws.
What magazines are compatible?
It uses AICS-pattern detachable box magazines. Factory 10-round Magpul AICS mags work perfectly, and you can use 5-rounders for hunting or benchrest.
