A buddy of mine in Iraq was the brigade Provost Marshal. He ran the brigade detention facility where they locked up bad guys before they got sent to on to bigger and better prisons (or let go). He took me to check out the confiscated weapons. Pretty sweet selection of AKs, russian pistols, a german Sig, RPGs, mortar tubes and sights, etc. Probably could have picked up what you were looking for there. Slightly illegal, though. Ok, highly illegal.
