Should I put anything such as moly on the threads of the muzzle device?

I went with a BCM 18" SS410 barrel and 12" LaRue FF handguard. It look like the gas block and tube have to be installed after the handguard is installed. Will it be fine if the tube is pinned to the block before installing them? The barrel uses a rifle length gas system.

If I remember correctly....you won't have any problem installing the Larue Rail after a low pro gas block and tube are installed.

I generally use barrel assembly lube.
I install gas blocks with gas tube already installed most of the time, it depends on the setup.
