Compact and light weight with excellent illumination - Nightstick Tactical Weapon Mounted Light

I have several diff brands of lights. I make my purchases based upon application. I dont want a long and heavy light on a bullpup style rifle or one I want to keep as light as possible. Some rifles are also already nose heavy so weight can be of great concern. This one works great for Bullpup style rifle especially if there's limited space for mounting. Streamlights are great and bright but one also has to be concerned about giving up your location at night, so how much will you really be using it when SHTF? Bang for the buck a great light which also takes "normal" CR123 batteries.
