Ok, that makes more sense. You are correct, these are functionally worth far more than $4k. In their OEM configuration, they are the ultimate long range I^2 clip-on, IMHO. I've owned 100+ NVDs at this point, in green and white phosphor across the whole spectrum of performance specifications. I love my high spec white phosphor stuff, but I must say that I am one of those weirdos that prefers life after dark in green. The only reason I bring that up is because you need to be absolutely sure you want the white phosphor and can accept the reduced recoil rating before moving forward with it. The white vs. green thing is purely my opinion, but there are other seasoned users who agree. Full disclosure, perception is big factor here and there are people who have owned/used as much or a lot more NV than me that prefer white phosphor.
