Adding white lights to traditional bolt rifles is aesthetically unappealing to me but using a light with a rifle may be necessary. It seems traditional round lights with tail cap switches would be difficult. What about flat lights with a side switch?
What got me thinking about this was a Kit Badger video where Ivan mentioned (if I remember correctly) he used an AK without a mounted light in a class but used a handheld light pressing the tail cap switch into a hand stop on the forend. This seemed like a good idea.
So to take it a step further, has anyone tried one of the newer flat lights on a bolt, lever, AK or other rifle holding it against the forend (wrapping the hand around the light and forend) and manipulating the side switch with a thumb to activate the light? Stable? Viable alternative or worse?
