the Barrel Band Forearm Mod...w/weaver picatinny mount

[soolio]

I just used a stainless steel screw to thread the existing holes since the mount is aluminum. I need to get an 8-32 tap myself 

EDIT I actually drilled open holes in the rail so that it would pull towards the bands*
The screws are 8-32x1/2*

Here are some close up pics. I filed all the edges since you have to hold it...I might touch it up, or not;)
