Right on par!! - ODIN Works Clamp-On Adjustable Low Profile Gas Block

Easily installed on AR 10 type rifle. Can quickly change the settings for different types of cartridges with the audible 'click' adjustments. Supers, subs, were no problem at all once you figure out the correct setting for each cartridge respectively. It fit neatly under the free float hand guard and is a breeze to switch back and forth between settings without having to remove the handguard. You will have to remove the hand guard to periodically clean the gas block and adjustment screw. Would definitely buy it again.
