PVS 30 will also clip on to any rifle, it doesn't have to be zeroed. It's by far the most simple NV device made. It has on/off/gain on one knob and a focus ring In the front, and that's it. So you can swap this between rifles with rails long enough to accommodate the clip on the scope. You can also score an ARD on ebay for a decent price that threads in and eliminates most reflection seen downrange.
I love my PVS 30. There is one that'll actually work better a couple hundred meters, but the rest of it is kind of unappealing, I think it has to be re-zeroed for each rifle too Some earlier clip ons were that way. The PVS 30 is heavy, it was designed to work on M2HB's but I need to see if it can handle the DTA HTI --recoil so brutal there. If so, I'd say it's bulletproof. Works on the SR25 like a charm, and will shine on the .338LM whenever I get it.
A good IR illuminator is key. I'd try and swing for a PEQ2 if you can score a good one but there's fewer around so keep looking on Ebay. PEQ15's are available there too, but the cost for one is a lot more than a PEQ2. Atilla 200's pop up from time to time, they're ideal too. Not sure if civilian illuminators work that well at those ranges and the LED ones give a glow. You need a full power IR laser illuminator, and they generally have built in lasers.
In short, can't go wrong with the PVS 30. At higher magnification, 17x-25x starts to get grainier and grainier but still useable.
Yes, I'd do it again, and mine had a rating of 1680 or thereabouts, I was expecting one much higher but a SNAFU ruined that. Anyway, I wasn't able to tell a difference between the two.
