Might take a look at the one NightForce sells. Same manufacturer, just 'beefed' up a bit and waterproofed to make it mil-spec for NF. A bit more $ due to these mods, but some have had issues with the other units getting water in them, etc. Just something to think about. It usually comes with a mount to fit on a pic or weaver rail. Can usually find a good deal on the web for it somewhere with enough looking.
