3 in 1 penetrating oil. We also have Kroil on the bench, but I like to save that for serious work since it stinks to high heaven. Yes, that is a factor.

One issue folks who are not in the suppressor game sometimes miss is the issue of seized / fouled threads. Suppressors have a tendency to blow gas a debris back through any thread it can find.

The result is a usually a device or mount that seems like it is welded into place. 

My solutions are to not let threads sit mounted for too long after shooting. Clean and lube threads consistently. And generally leave threaded items partially unthreaded when in long term storage.

Lock the Silencerco tool in a vise for better grip.

The last step usually keeps things from being seized up, but also allows easy access to the threads with penetrating oil should the need arise. That is not what is happening here.

Left on bench overnight. Came in next day and…problem solved.

The thread insert on our Silencerco Harvester is seized and I need to change it for a different thread pitch. The solution is to let penetrating oil sit on it overnight, and to then mount the Silencerco tool in a vise to unwind the bastard. 

Works like a charm.
