These absolutely work and they are absolutely on sale so if you are looking for an inexpensive leash system for your NVGs then the NOD Retention Lanyard from Down Range Gear is the one for you. It’s a simple mod to install. You just place the lanyard between the helmet and mount.
There are a couple of places that carry DRG products but I know that OP Tactical currently has them on sale.

1-hole model we have a bunch ready to go.
