So I had a left over piece from the P90 that I butchered, and noticed that it looked a lot like the rear portion of the top-rail of the Multi Tool. So with the gods on my side I took the risk of butchering the already progressed product in hopes that I could insert the piece and still have the (very hard to see in the picture) FUNCTIONING bolt action WORK.

Sure enough with enough butchering and sanding, IT WORKS!!

Now just have to finalize the front portion and add on a prominent Shoulder stock and BAM!
