Improving your Benjamin Kratos, Akela, and Cayden vented shroud

I took a piece of the foam from an empty can of JSB Pellets, cut a strip about 1/2” or 3/4” wide and maybe 2” long or thereabouts. Just long enough to wrap the barrel. This foam inside the shroud slows the air down that is escaping the shroud vent in the threaded fixture. This has given my Kratos a deeper tone and reduced noise noticeably. Well worth the effort. Give it a try guys and see how it works for you! I’m super happy with it.
