Pic rail for Daystate Wolverine??

[Roadking]

I am wondering how to attach a small Picatinny rail to the bottom of the fore end of a DS Wolverine. I want to be able to attach a bipod.

From looking at the small space between the fore end and bottle, I am not sure this is something you can do.

If anyone has done this, I would appreciate knowing how you accomplished it.

Thanks, RK.
