This. It's all about weight and durability for rifle cans.

The only good way to clean a sealed suppressor that I know of is using "The Dip." It will dissolve the lead and help break apart the gunk caked inside the suppressor. THIS IS VERY DANGEROUS. It creates TOXIC VAPORS and LEAD ACETATE which is READILY ABSORBED THROUGH THE SKIN. It MUST be done with PPE, OUTDOORS, away from anyone or any thing that can't understand the danger, and the liquid is thereafter highly toxic and must either A. be disposed of at a hazardous waste facility or B. have the lead 'crashed out' by someone who knows what they're doing.

I wouldn't mess with it unless you're confident with chemistry and PPE use or your DGAF meter has reached the "I could spare a couple dozen IQ points, am tired of thinking about concepts more complex than basic impulses, and don't mind constant headaches for the rest of my life" line.
