The pictures show a short length of Aluminum Tube split with a hacksaw and placed around the PTFE Barrel mount. This should give the PTFE some degree of heat sinking and help it run a little cooler.
I would rather have used a finned heat sink but lacking a lathe I had to settle for a straight tube.
As is usual I used a hose clip as well. both to make a good contact and to hold it all together just in case the heat sink doesn't quite work as planned.
