How the .... do i add a foregrip

[POOoOoOPs]

I just got my automag classic, barrel, foregrip, bottemline in the mail today and i cant figure out how the hell i add the foregrip!!! Where does it go into? I bought a benchmark foregrip if that helps. Its made for automags too. I guess im lost or somthing.

Take the body rail off the gun. Then look near the front of it, there is a hole that isnt drilled all the way through. Just get a drill or a punch of some sort and knock the bottom out of the hole. Then put your foregrip on!
