Dimple for gas block set screws
As a more foolproof way to secure a gas block to a barrel, adding dimples to a barrel in one or two locations helps the set screws locate and bite into the barrel. Please note that when we dimple a barrel, our dimple jib locates off the gas port, so if your gas port is not exactly at 12 o'clock, your gas block will be slightly canted.
