Faxon Firearms Match Series Gunner Barrel – .300 Blackout, 7.5-Inch QPQ Nitride

The Faxon Firearms Match Series Gunner Barrel in .300 AAC Blackout, 7.5 inches, QPQ black nitride finish (brand part no. 15B35P7NGQ-5R-NP3) uses Faxon’s Gunner profile to blend the durability of a GOVT contour with the weight savings of a Pencil profile. That balance shifts weight back toward the shooter’s body, reducing fatigue during long shooting, training, or hunting sessions. The 300 Blackout cartridge is well suited to shorter barrels like this one, delivering strong performance and effective subsonic capability. Faxon fully stress relieves and air-gauge tests every barrel, then finishes it with an 11-degree target crown for accuracy.
