Questions & Answers
Is the gas block adjustable? Expert Answer

The Faxon Firearms AR-15 Goverment/Socom Profile Threaded Barrel does not include an adjustable gas block. Included is the Faxon 3 Screw low profile gas block (non-adjustable).

by Ethan, Gear Expert, March 10, 2025
Will this barrel be compatible with the smith and Wesson M&P Sport 2 and if so would i need a new front site and gas block combo? Manufacturer Answer

These barrels will fit the M&P-15 Sport 2 receiver, however, the front sight tower and handguard will not be compatible. This listing is for barrels that include a gas block, but you will likely need a new handguard and gas tube to suit the barrel.

Great barrel, but pinned gas block needs work by Joe M, Verified Owner, June 18, 2023
I received my first 16 inch barrel only to discover that the muzzle had a large gouge taken out of it. QC issues happen, so I returned to OpticsPlanet and got a nice replacement. The head space was tight (just barely closed on a NATO go-gauge with my...

Product Info for Faxon Firearms AR-15 Goverment/Socom Profile Threaded Barrels

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.
