Description

300 PRC Prefit Carbon Fiber Barrel

The 300 PRC is a modern magnum cartridge designed for long-range performance, combining high ballistic efficiency with the ability to use heavy, high-BC bullets. Its long-action magnum design makes it an excellent choice for long-range hunting, precision shooting, and applications where extended-range performance is a priority.

This Helix 6 Precision 300 PRC 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 300 PRC is particularly well suited for shooters looking for a combination of high velocity, heavy-bullet performance, and long-range capability in a modern magnum cartridge. Its design is optimized around long, high-BC projectiles, making it an excellent choice for long-range hunting and precision shooting.

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