Dredd Shotgun Sling Mount

Hi all i'm trying to identify this Sling mount from the Dredd 3D 2012 Shotgun {aka Widowmaker} for a friend & I was hoping the forum could help. Of course it has to be the same sling mount & not something similar. Thanks in advance for any advice.

looks like a Fixed Staple Hasp Lock (had to look it up lol) but cant find from what

The original picture looks to have a triangular shaped loop? May be a lightweight version. Still, it's a step closer & another thing to check out?
