Description

 

Faxon FX7 Prefit Barrel — 22" .308 Win Medium Sporter Profile (1:10 Twist)

416-R stainless • 5R button rifled • Honed & lapped • Salt bath nitride (QPQ) • 5/8x24 • Recessed target crown • MPI inspected

The Faxon FX7 Prefit 22" .308 Winchester Medium Sporter barrel is built for shooters who want a true bolt-gun workhorse: accurate, durable, and balanced for field carry or range time. This is a prefit barrel engineered for the Faxon FX7 action.

Starting with 416-R stainless steel, the bore is 5R button rifled then honed & lapped for smooth internal finish and consistency. A salt bath nitride (QPQ) treatment boosts corrosion resistance, reduces fouling, and supports long service life. Each barrel is MPI inspected and finished with a recessed target crown to protect accuracy at the muzzle.

Key Benefits

  • FX7 Prefit interface: Built to pair cleanly with the Faxon FX7 action.
  • Medium Sporter contour: Great balance of stiffness and carry weight for hunting and practical precision.
  • .308 Win, 1:10 twist: A proven twist rate for common .308 bullet weights and classic performance.
  • 5R button rifled, honed & lapped: Smooth bore finish for consistency and easier cleaning.
  • Nitride QPQ finish: Corrosion resistance and reduced fouling for hard-use longevity.
  • Built for suppressed or unsuppressed: 5/8x24 muzzle threads for easy device and suppressor mounting.

Frequently Asked Questions

What actions is this barrel compatible with?
This is a Faxon FX7 Prefit barrel. Always verify your action specs and confirm headspace with proper gauges.
Is this a “drop-in” barrel?
Prefit barrels are designed to streamline installation, but final safety checks still matter. We recommend installation by a qualified gunsmith and always verifying headspace before firing.
What does 5R rifling do?
5R is a rifling geometry designed to reduce bullet deformation and can help with consistency and cleaning compared to traditional land/groove forms. Combined with a honed & lapped bore, it supports strong accuracy potential.
What muzzle devices fit this barrel?
The muzzle is threaded 5/8x24, a common standard for .30 caliber muzzle brakes and suppressor mounts. Confirm device compatibility and shoulder/taper requirements for your specific mount.
