11.5" BIG GUNNER, 5.56 NATO, MID-LENGTH, 4150 QPQ
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 1/2x28 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 releived, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
Quality is imbuned 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.

*As this barrel is likely to be used in full-auto applications, we are opting to stick with a 5.56 chambering to ensure absolute safety for our customers.
**Due to the short dwell of the barrel, the gas port will be larger than most barrels. Customers are encouraged to use an adjustable gas block for optimum functionality.
