Christensen Arms Summit TI .300 Win Mag 26″ Thumbhole

If you’re building a long-range rig that needs to pack into the backcountry and still deliver consistent 1/2-MOA groups, the Christensen Arms Summit TI .300 Win Mag 26″ Thumbhole is the kind of rifle that makes you question why you ever carried anything heavier. This full-size bolt action pairs a carbon fiber-wrapped barrel with a titanium action and radial muzzle brake, keeping the weight manageable while the .300 Win Mag cartridge gives you the reach to stretch past 1,000 yards on elk or steel. Christensen Arms backs this with a 1/2-MOA accuracy guarantee—and from my time behind similar Summit TI builds, that’s a conservative claim.

Key Features

• Carbon Fiber-Wrapped Barrel — Reduces weight by roughly 30% over a steel contour of the same profile while maintaining stiffness. That means less fatigue on the mountain and faster follow-up shots without the barrel whipping.
• Radial Muzzle Brake — Tames the .300 Win Mag’s recoil impulse, letting you spot your own trace. If you run suppressed, the threaded steel muzzle (5/8×24) makes mounting a can straightforward.
• Thumbhole Carbon Fiber Stock — The ergonomics lock your hand into a consistent grip position, which translates to repeatable trigger pulls. The carbon fiber construction also sheds ounces over traditional laminate or synthetic stocks.
• 1/2-MOA Guarantee — Christensen Arms will test-fire and certify the rifle to shoot 0.5″ groups at 100 yards with match ammunition. That’s not a marketing slogan—it’s a performance floor.
• 3+1 Detachable Box Magazine — Enough capacity for a hunting scenario or a PRS-style stage, with a flush-fit design that doesn’t snag on brush or barricades.

Who It’s For

This rifle is built for the precision hunter who needs one platform for both a 600-yard mountain shot and a 1,200-yard steel target. If you’re the kind of shooter who weighs every ounce and still expects half-inch groups, the Summit TI is your ticket. It’s also a solid choice for the long-range competitor who wants a lighter rig for multi-day matches without sacrificing the .300 Win Mag’s wind-bucking ability.

Pros & Cons

• Pro: Sub-6.5 lb weight with a 26″ barrel—hard to find in a magnum that holds 1/2 MOA.
• Pro: Radial brake is effective enough to keep the .300 Win Mag pleasant to shoot from field positions.
• Pro: Carbon fiber stock offers a natural, repeatable cheek weld for consistent eye alignment.
• Con: The thumbhole stock can be a tight fit for shooters with larger hands or those who prefer a traditional vertical grip. You’ll want to handle one before committing.
