Yes it's a Burris XTR 1-4x in a Bobro 30mm mount.
Looks like you have one of the new Nordic extensions for PMAGs. I have one of those too but haven't shot with it yet.
For that really low port stage I did the Urban/Roll-over prone which worked well for me. I was using 30 round PMAGs for this stage.
