I tried installing my turbine core II SA and discovered that althought the holes line up well they are designed to have some rubber grommets inside them, but alas none in the bag with the silencer. (I would have gladly traded them a few stickers back for hardware.) I called FMF and they verified that there is supposed to be some mounting hardware included in the bag so they will be shipping some off to me today. Just want all to know as a "heads up" if you get a silencer and have a hard time figuring out how to mount it.
