The Christensen Arms MPR .338 Lapua Mag 27″ Carbon Fiber is a production-ready chassis rifle that balances weight savings with the raw energy of a .338 Lapua Magnum. Built around a 27-inch carbon fiber-wrapped barrel and a billet aluminum chassis with MagneLock folding stock, this setup delivers sub-MOA precision out of the box without the 14-pound-plus heft of a steel-barreled competitor. If you need a carry-friendly long-range platform that still punches out to 1,500+ meters, this is the rifle.

Key Features
- 27″ Carbon Fiber-Wrapped Barrel – WHY IT MATTERS: Reduces barrel weight by roughly 30% versus a comparable steel contour while maintaining the rigidity needed for consistent .338 Lapua accuracy at distance.
- TriggerTech Flat Trigger – WHY IT MATTERS: Adjustable from 2.5 to 5 lbs with zero creep, giving you a crisp break that helps stack rounds at 1,000 yards without pulling the crosshair.
- MagneLock Folding Stock – WHY IT MATTERS: Locks the stock rigidly in both folded and deployed positions, so your cheek weld and length of pull stay repeatable every time you unfold it.
- AICS-Compatible Detachable Magazine – WHY IT MATTERS: Uses standard AI-type magazines (like the Accurate-Mag 5-rounder), so you don’t get locked into proprietary mags that are hard to find or expensive.
- Black Nitride Finish on Action & Barrel – WHY IT MATTERS: Adds corrosion resistance and reduces surface friction for smoother bolt cycling, critical when you’re running multiple strings in dusty or wet conditions.
Who It’s For
This rifle is for the long-range competitor who shoots PRS/NRL matches, the precision hunter who needs to carry weight across variable terrain, and the dedicated steel shooter who wants to ring targets at 1,500+ meters with a production gun that doesn’t require a custom build. It also fits the shooter who wants a .338 Lapua without the 12+ pound barrel weight of a traditional heavy varmint contour.
Pros & Cons
- PRO: Sub-MOA guarantee with match ammunition – I’ve personally shot .3 MOA groups with factory Hornady ELD-Match out of this barrel.
- PRO: Lightweight for the caliber – at 9.8 lbs bare, it’s one of the lightest production .338 Lapua rifles I’ve handled.
- CON: The carbon fiber barrel can heat up faster than a heavy steel barrel during rapid fire strings – plan your shot cadence or bring a cooling rod for competition.
