VIS, I am impressed. You have put a lot of thought into your design, not to mention a lot of work.
It looks like I will have to come over to Gunco.net more often. It seems no one is interested in building bullpups on the AK.net. It appears my Shadowpup is the last bullpup built by AK.net members.
I hadn't realized there were so many "shadetree gunsmiths" on Gunco.net. I am about as "shadetree" as they come.

Although I do have a number of designs to my credit.
Unfortunately for me, I have sold my shop, and home, it may be a while before I get another built. Heck, I haven't even decided what state I am going to wind up in yet.
Are you going to use a Sten magazine to convert a SOUMI 71-rd drum to fit your 9mm bullpup? It certainly would make it look even more evil!
