416-R stainless • Button rifled • Honed & lapped • Fully stress relieved • M24 contour • Precision blank for custom builds
The Faxon 27" .308 / .7.62mm Bull Profile Barrel Blank is engineered for gunsmiths and precision rifle builders who require maximum rigidity, thermal stability, and accuracy potential. With a heavy bull contour and premium internal finish, this blank serves as a rock-solid foundation for long-range, competition, or tactical rifle builds.
Crafted from premium 416-R stainless steel, each blank is button rifled, honed and lapped, and fully stress relieved to promote uniform internal geometry and long-term dimensional stability. The 1:10 twist rate supports a wide range of .308-caliber bullet weights for versatile custom chambering.

Builder Notes
- Ships unchambered & unthreaded: Your gunsmith selects the final chamber, tenon, and muzzle threads.
- Versatile 308 twist: 1:10 is a widely used twist rate for many modern 308 projectiles.
- Planning tip: Confirm action, intended cartridge, and suppressor/muzzle device requirements before final machining.
Note: Barrel blank ships unchambered and unthreaded. Final dimensions, chambering, contouring, threading, and finishing are the responsibility of the gunsmith or end user.
