From the muzzle back to the gas block .300 AAC Blackout Gunner Barrels match Faxon’s skinny "Pencil" profile to keep weight down and preserve ease of handling. There’s more metal from the gas block back to the barrel extension to provide rigidity and combat distortion due to heat buildup during long shooting sessions.
