heres how i made my 15* foregrip.
get a bottomline asa that is angled like this. (sorry i cut it already)


now either strap to a straight surface or bolt it on ur trigger frame and put it in a vice.(sorry no pic) now cut the asa in half like the image above. make sure its a pretty straight cut. notice how i still have one bolt hole.
take your body off but leave your rail on. install a nut on top of the front screw and field strip screw.

ok now that you cut the asa in half (o hopefully didnt cut ur frame too bad
) hold it against your rail and trigger frame. like so.

now you can either mark, drill, and tap into the frame or mark, drill, tap into the asa. I recommend tapping the asa due to it having more to tap into.
in the frame

into the asa

i used a 10-32 tap with a 5/32 drill bit. (same bolt threads as the front screw.)
Bolt your asa up to your rail or frame(whichever one you tapped) and reassemble your gun.

Congratulations! now u have a working 15* foregrip.
let me know if u need anymore pics.
