The 'A-Nuts' from USGI PASGT Helmet Suspension Liners were very commonly used by Special Forces for attaching NVG Mounts where a standard hex nut might protrude in and lead to potential injury
Here I'm using one to install a CAG 2-Hole NVG Shroud to my Protec ACE Skate Helmet to run as my night vision bump helmet
more goofy modifications to come later
