338 Lapua Pre-Fit Carbon Fiber Barrel

The .338 Lapua Magnum is a powerful, long-range magnum cartridge designed for high-velocity, heavy-bullet performance and exceptional downrange energy. Its long-action magnum design makes it an excellent choice for extreme-range shooting, big-game hunting, and applications where extended-range performance and retained energy are a priority.

This Helix 6 Precision .338 Lapua Magnum Prefit Barrel features a match-grade 416R stainless steel core wrapped in our proprietary carbon fiber construction. The result is a lightweight, stiff barrel designed to maintain accuracy and minimize point-of-impact shift as temperatures rise and shooting strings extend.

The .338 Lapua Magnum is particularly well suited for shooters looking for a combination of heavy-bullet performance, long-range capability, and retained downrange energy. Its ability to use large, high-BC projectiles makes it a proven choice for long-range shooting and big-game hunting applications where extended-range performance matters.

Each Helix 6 barrel carries a sub-½ MOA accuracy guarantee when used with match-grade ammunition, quality components, and by a capable shooter.
