I recently had the pleasure of trying out the Fenix TK32 flashlight. I mounted it up to my predator gun and went to the field to test it out. All I can say is wow this light packs a punch for its size! Plus 2 intensity levels of red, 1 level of green and 4 white all controlled by 2 switches on the tail cap for easy control in the dark.
I mounted it to my Picatinny rail using the ALG-00 mount which is QD for easy on and off mounting. For predators under 300 yards this light is all you need!
