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.
