Nice flashlight end cap for emergencies.
Not sure what the other reviewer is going on about but I installed the Bust-a-Cap on my 2-D cell Maglight and th e fit and finish is excellent. Seems very durable and solid. I mounted the flashlight in my truck in the center console using Maglights own mounting clips. As a side note this caps point is sharp enough it could be used as a weapon if no other weapons are at hand.
