16 Inch High-Quality Barrel For 6.5 Grendel Rifles

This Faxon Firearms Match Series 16 Inch Gunner Barrel is designed specifically for the 6.5 Grendel caliber, giving you an ideal option to send heavier rounds downrange, at longer distances than 5.56. It carries the high standards of the Gunner profile that brings the balance of the rifle back towards the shooter’s body and helps limit fatigue to ensure maximum versatility for any shooting activities.

The Gunner profile combines the durability of the Government profile with the weight savings and maneuverability of the Pencil profile for the best performance.

Unparalleled Durability & Optimum Accuracy

The Faxon Firearms Match Series 16 Inch Gunner 6.5 Grendel Barrel is crafted with 5R hybrid rifling that results in increased velocity and easier cleaning. The extension is coated in Nickle Teflon which enhances dry lubricity and corrosion resistance while also creating a tighter, more secure fit.

It is built from 416-R Steel, individually checked for headspace by precision custom hardened PTG gauges, and goes through rigorous testing to ensure durability and optimum accuracy.

Note: This barrel is 6.5 Grendel Type 2.  Be sure to use a compatible 6.5 Grendel Type 2 BCG.
