front grips with Green laser?

I was at my local gun dealer today looking at accessories for a Ruger SR 556 and he showed me a front grip by Crimson Trace that was a forward grip/flashlight/red laser. I like it alot but I want the green laser rather than the red. Does anyone know about such an item by another manufacturer that is similar to the Crimson Trace model #MVF-515 with the green laser? Any help would be appreciated. Thanks in advance.
