i bought the scope new through a litton authorized dealer www.nightline-inc.com/NightVision/en/products/ws2150.php
about 2 1/2 years ago. i have about 30 hours of use on the unit, batteries have been changed once. they marketed the scope as the nighthawk but is the common name is the aquilla III.
tube is a 64 lp with excellant performance but no spec sheet. from other scope i've had that did have spec sheets, i would say this one has a signal to noise of around 24:1, the image is relatively sparkle free in total darkness and there are no black spots to speak of.
recoil rated for 50 bmg but i have been using on a ar15 so it's had an easy life of plinking rocks, water jugs and paper. the reticle is a super fine red dot with a variable brightness control. windage and elevation are adjustable in 1/4 MOA clicks for windage and 1/2 MOA in elevation.
wanting to sell only, no trades please. price is $4500 shipped and insured with signature required for delivery. sales are for a US citizen with no export. acceptable forms of payment will be bank drafts or credit card only. NO personal checks or money orders from circle k and the like, please. thanks, scott in tucson
