They do not do much for spring guns I found.
“Add on suppresors (we call them lead dust collectors) are popular with the pre-charged pneumatic pellet rifles and pistols.

Agree. The PCP guns have a consistent pre and post pop that is well handled by the dust collectors. Not all folks who use spring air get past the 1000 pellets needed to diesel off all the oil preservative and after that, just not an issue. The Brits can, and are encouraged, to put a can on just about any air or rim fire rifle.
