I have gotten the Doc for the Twin Barrel Shotgun (Rubber) but it won't show up for me to actually spend the GMP to create it. I have gotten my R&D Level to 90 and I still can't make it. Is there any other requirements I am not seeing? I need help b/c I am about to finish all the extra ops missions and the rubber slugs would really help me get S Rank.

You'll need to research the regular Twin Barrel Shotgun to Rank 2 and then it should show up. Here's a guide for what you need for all the weapons:
