It's been a while and I remember a thread about suppressor covers but cannot find it so I'm starting a new one.

I'm looking for a suppressor cover for a Surefire SOCOM 7.62. My main concern is defeating mirage. The only cover experience I have is an ancient Bowers Group griptastic cover that I use on a 5.56 can.

Has there any new technology since then? What are you all using?
