Hey y'all, I had to do some contouring on my gas block to get it to clear a handguard (gas block was a cut-down FSB originally done by factory, not me - I had to take the corners in a bit). Anywho, I'm thinking I ought to paint the bare metal. But gas blocks get hot. So do I need to use a special kind of paint, or just some Alumahyde and call it hunky-dory? Any thoughts?
