White light on a weapon, a ???..............

A light?
Just use the combat sights located on the top of the C79 sight.  The little pricks up top there...Good enough...Don't need optics on that weapon anyways.

  Dude, I'm not going to tell you how ridiculous your statement is and embarrass you, there are individuals here that are much more qualified, experienced and just plain cruel than I to do that to you.  To be fair though, your statement isn't completely false.  One doesn't require optics on their C7/M16/AR15 series rifle for effective close and medium range shooting.  However, most shooters usually opt for one because they can utilize these tools to improve their fighting.  Besides, the mounted light isn't supposed to be used as an aiming device, only to illuminate an area or target.

True, I realized after I posted...I got the general impression it's a stay on all the time kinda thing...Accidental slip
