I ran across this picture on one of the facebook groups dedicated to MACVSOG history. Unfortunately the person who posted it offered no details since he had none to give. The AK is suppressed with what looks to be a Scionics suppressor. I have no idea what model. The barrel and front site have been modified to either accept the suppressor or to make it a bit more compact. The claim was made that it was used by SOG recon team members but I have no idea if that’s true. It probably is. SOG teams used and evaluated a crazy amount of weapons. Some useful some not so much. The Gyrojet pistol comes to mind.
