Scope Mount

These are bike mounts that work extremely well on the scope and possibly the barrel with a spacer. I've got a couple friends who absolutely love them for possums. You can use the torch to search and then snap it in to take the shot. Gun City sell them for $40.
 
These are only compatiable with the C8+ model with a 44.5mm head diameter and smaller. 
 
I recommend a strip of insulation tape to stop the torch and scope coming into direct contact. You could use a thicker spacer to lift the torch a little higher. The shown scope has a 40mm optic and is 46mm in diameter.
