You’re looking for a 10.5” 300 Blackout barrel or 16” 300 Blackout barrel. You want a barrel that surpasses expectations, and pushes beyond the “standards” set by other manufacturers in the industry. Faxon Firearms is the manufacturer for you.
A Hybrid Profile Like No Other
If you’ve ever wished you could have the stout reliability of a government profile barrel and the agility of a pencil profile barrel you know that you’re asking for the moon. Faxon can deliver on that wish with the Faxon Firearms GUNNER Profile 300 Blackout Barrel.
Faxon’s GUNNER barrels offer the best of two very different worlds in one package. The GUNNER Faxon 300 blackout barrel takes its rear section from the government barrel profile. From extension to gas block the GUNNER resembles the stout taper of the government profile barrel. From the gas block journal forward, the GUNNER is a pencil profile barrel. Less weight out front lets you maneuver with greater agility while the extra material kept in the government profile portion of the barrel helps to keep things under control and resist the effects of heat buildup.
Faxon Quality from Steel Blank to the Last Touch
Faxon manufactures their barrels 100% in-house, so they maintain complete control of every process and there’s no lapse in accountability. Everyone who participates in the production of a Faxon barrel is part of the Faxon team, that means they’re invested in and accountable for the final product. The result is a line of barrels like no other.
The Faxon 300 blackout Barrel is manufactured from certified 4150 gun barrel quality steel. Each one is stress relieved and air gauge tested so you don’t have to worry about early failures. Quality 1:8 twist button rifling assures long-term reliability and accuracy shooting your chosen load without worry. From start to QPQ Nitride finish, Faxon Firearms means quality.
Whether you choose a 7.5" 300 Blackout barrel, 10.5" or a 16” 300 Blackout barrel you get the same great quality and attention to detail. There’s no need to look for a separate manufacturer for your long and short barreled 300BLK builds, Faxon quality is available in both. Why would you want anything else?
