If that rail is screwed on you might want to remove it are move it. Looks like the block could be contacting the screws that hold the rail to the handguard.

Ok. So it's a clamp on style. Remove the hanguard and loosen the screws and line the gas block back up with the gas port. Put some lock tote on the screws and tighten it back down.
