My R10 .177 was pretty quiet with the stock moderator. I tried a DonnyFL and a 0dB but the stock moderator was still more quiet. My wife still thinks the rifle is too loud for the neighbors so I thought I would try this Huma Air shroud that has been around for a few years, marketed under the inventor's name. (I think Huma Air must have bought him out) Anyway, the rifle is the now the quietest of all of my guns, including my Daystate Air Wolf .22 with the Huggett Snipe and shroud. Installation was simple and the results is amazing. (In the Huma installation video it shows the guy doing some cutting on the screen inserts, but that is not necessary) For you guys who like "stuff" in their moderators, you will like this. The look is bull-barrel with a clean muzzle.
