Faxon
Faxon FX7 Prefit Barrel — 20" 6.5 Creedmoor Gunner Profile (1:8 Twist)
416-R stainless • 5R button rifled • Honed & lapped • Salt bath nitride (QPQ) • 5/8x24 • Recessed target crown • MPI inspected
The Faxon FX7 Prefit 20" 6.5 Creedmoor Gunner barrel is built for shooters who want a do-it-all bolt-gun setup: capable for hunting, practical precision, and long-range range time. Designed as a prefit barrel engineered for the Faxon FX7 action, it combines an efficient contour with accuracy-focused barrel making.
Starting with 416-R stainless steel, the bore is 5R button rifled, then honed & lapped for a smooth internal finish and consistent performance. A salt bath nitride (QPQ) finish enhances corrosion resistance and reduces fouling. Each barrel is Magnetic Particle Inspected (MPI) and finished with a recessed target crown to protect accuracy at the muzzle. Proudly American Made by a family-owned company in Greater Cincinnati, Ohio.
Ideal Use Cases
This 20" 6.5 Creedmoor FX7 prefit is a sweet spot for real-world bolt-gun performance: manageable length, excellent bullet selection, and suppressor-ready threading.
