Re: Do you ever take your Can off?
Hell yes.
One of the chief reasons for suppressor degradation is condensation inside the tube corroding carbon steel. I take mine off after every session and run hot dry shop air through them; a hair dryer is a good second choice. Second, .22 suppressors can fill up with carbon and lead to the point of not being able to remove the baffle stack; a good soak in Carbon Killer will help that, just remember CK will etch aluminum and remove anodizing; third and finally, as stated by other posters, carbon buildup on the threads can make removal a)difficult b)frustrating c)*&@#!&!! impossible - sorta. When removing and reinstalling, I use a small dab of anti-sieze on the all the threads: can ends, barrel mounts, everything. Trust me, you'll thank yourself.
