If you’re looking for a more robust mounting method for your gas block… look no further. Pinning your gas block, in addition to the use of set screws, gives the user the extra piece of mind that your gas block won’t shift or loosen while firing.

We took some of our most popular barrel models and took the biggest headache out of pinning your gas block by pre-notching the gas block journal and drilling corresponding holes in the included low profile gas block.

Each Pinned Gas Block Barrel comes with the pin, as well as a gas block. Gas blocks are hand-tightened to the barrel for shipping.

The Gunner profile is a blend of two of the best performing profiles of all time, Gov’t and Pencil. Faxon’s Gunner profile combines the durability of the Gov’t profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter’s body, limiting fatigue, and allowing for shooting, training, or hunting all day long.

Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Cincinnati, Ohio, Faxon 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 beginning of the manufacturing process.. 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 with precision PTG gauges.
