This shows a couple the ways to shoot the Advisor using a Sling and Hand Stop or a Angled Forward Grip
for added support.
This is using a Mini Draco, but the procedures are the same. I will do a video using my Advisor in the near future.
Another AK Pistol with a single point sling.
This is a nice well made sling, that works for single or 2 point use,
and transitions from one to the other very easy, and the length changed
with just your thumb. It was $19 with shipping, and took just over 1 week.
They have it in several colors.
