Designed for those looking to save weight while still allowing for the use of a suppressor long-term, the BIG Gunner is ideal for suppressed shooters. All for just about a single pound!

Behind the gas block will be a Government profile tapering to a shoulder and 1.1″ journal .625 gas block. In front of the gas block, the barrel will continue straight to a 1/2×28 muzzle with full shoulder.

Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100  quality certifications.

    This barrel is solid. High quality and accuracy is spot on. Between consulting with Faxon and ordering from BKings, everything from start to finish was professional. Blake and Jon are the real MVPs

    LOVE IT! BKF is out of this world fantastic! Order, built and delivered in less than a week! Would have been sooner except UPS didn’t deliver on Saturday. Huge fan of BKF! Can’t say enough good about them! Will definitely buy another build and will not look anywhere else!
