I second the usb powered chamber fans. It made a noticeable difference in how long I had to wait in between shot strings. A cheap rechargeable backpacking mattress fan off Amazon and a piece of tubing is all it takes.USB-powered chamber cooler fan between shots/strings, or USB-powered square fan pointed at the suppressor to blow away the mirage and speed cooling of the can.
Suppressor cover also works for a few 10 round strings, but then there's a heck of a hot potato to deal with when casing the rifle at the end of the range session.
