Call Of Duty 4 gun and Paintball Gun?

[Michael C]

I need some help. I have a Tippmann Alpha black and I would like to make it a m4a1 carbine SOPMOD, like the one in Call Of Duty 4 Modern Warfare. The only thing is that I don't know where to get the flashlight/laser on the side of the gun.

Here is a picture...
