These AR10 Gas Blocks have increased height to allow for easier install and less pressure on the gas tube, especially for pistol and carbine-length builds.

The gas block clamps on to the barrel using 3 Allen keys on the bottom of the block. 

*Faxon Firearms highly recommends the use of Loc-Tite or similar thread-locking compounds. Gas blocks will get very hot, so pick a compound according to your intended use of the firearm.

    This gas block fit perfectly on my Faxon 16 inch 8.6 Blackout barrel. It's good looking and functions great. The price was right and the shipping was super fast. Thanks
