The Faxon Match Series 18" Gunner 6.5 Grendel barrel delivers exceptional balance, accuracy, and consistency in a lightweight mid-length configuration. The Gunner profile blends the strength of a Government contour with the reduced weight of a Pencil barrel for improved handling and all-day precision.

Machined from 416R stainless steel with 5R button rifling, this barrel provides outstanding accuracy and easier cleaning. Each Match Series barrel is Nitride treated inside and out for maximum corrosion resistance and long life, and finished with a Nickel Teflon–coated M4 extension for a tighter, smoother receiver fit.
