Re: Should I put lube on suppressor adapter threads?
If you can find it, I recommend Molykote 1000 anti-seize. It's a Dow Corning product but I get free sample tubes from Sandvik sales people. We use them on torx machine screws that hold carbide inserts to face mills. We run these tools dry (no coolant) through heat treated stainless and exotic superalloys, sometimes to the point where the carbide inserts will start glowing cherry red with long cycle times.
The petroleum based suspension fluid will evaporate from the heat but the high concentration of molybdenum disulfide solids remain. I've never snapped a screw head or had one seize in the 5+ years I've been using it. I don't think anything short of a full-auto shoot approaches the thermal and mechanical stress seen in dry machining so it's good to go. I've pretty much switched anything requiring anti-seize to it including my cans.
