The Vampire in my opinion is "PFG" purdy fukin good. So much that I recommended to a few friends, then after they actually saw/used/compared, they each bought one. Both of these guys were combat vets and intimate with night vision. Range and clarity are great. I put it on "Snoopy" and I pulled a 4" group at 100yds using federal .223 green box ammo. This thing comes with a IR external mounted light adjustable to narrow and wide beams. They one's they bought has a new updated IR system, even better!

Now having said all that, environmentals will have an effect, as with any night vision. Having been in a situation where we couldn't distinguish the horizon line, not a good thing with a helo, sucks more being a pax and can't do shit but squeeze you butt cheeks together and pray till we touch down. Like I said, "environ-mentals"

The RS64............let's just say it's the most expensive mouse hunting tool I've ever seen. In short, this things fuckin dangerous. Never mounted to toy yet so don't know how they shoot. But looking through one once it's tuned to your eyeball.........wish I had one 15 yrs ago. Would've saved a few patch jobs in the boats.
