Faxon Firearms AR-15 11.5" Gunner, 5.56 NATO, Mid-Length, .625 Gas, 4150 QPQ, 1-8T Barrel

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, the block will be a Government profile tapering to a shoulder and a 1.1" journal .625 gas block. In front of the gas block, the barrel will continue straight to a 1/2x28 muzzle with the 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 Faxon Firearms barrels from the start. Faxon Firearms 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. 

General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking and extracting a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-15 Pistol barrels can be chambered in a variety of different calibers, spanning from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.

About This Barrel: The Barrel is made by Faxon Firearms it is 11.5" long, and is machined from 4150 Chrome Moly Vanadium, and is finished in a nitride appearance. Chambered for 5.56 NATO, using a medium profile design, this barrel will fit your next AR-15 build perfectly.

About the Profile: Medium - Medium Profile barrels are designed to have an even weight distributed from the beginning to the end of the barrel, this results in a rather tubular-looking appearance but with identical rigidity and properties to a government profile barrel.

Barrel Classification: Pistol

Length: This Barrel is designated as a pistol length barrel with an overall length of 11.5".

Caliber: 5.56NATO - This barrel is chambered to fire both 5.56 NATO and .223 Remington, the most commonly used round designed for the AR-15 platform.

Material: 4150 CrMoV - Chrome-Moly Vanadium, or simply "CMV", is the official mil-spec gun steel developed by Colt Firearms for the military-issued M16 and M4. It contains the same elements as 4150 steel. It also contains Vanadium. Vanadium significantly increases the strength, hardness, and high-temperature stability of the steel.

Finish: Nitride - Nitriding is a process during manufacturing that diffuses nitrogen into the steel to make a case-hardened surface for improved resistance and strength. A Nitrided barrel typically have a gloss black texture.

Thread Pitch: 1/2x28 - This threading is commonly found on barrels chambered in 5.56, .223, and .224. This will allow the installation of most muzzle devices such as flash hiders, blast cans, and compensators threaded to 1/2x28 threads.
