Used to mount the PVS-14s on everything. We ran them as a monocular on a head-rig, rifle mounted, on the 240s, anything we could have the unit armorers mount a piece of pic rail to and still get a good sighting setup. Those were the military issued PVS-14s, not the cheaper versions.
Which brings up a great point. There's lots of companies that make a "PVS-14," and you'll see alot of different prices. The really expensive ones are the real deal, there are only a small/few companies that make them, and will hold up to anything you can throw at them, or mount them to.
