So I picked up one of these almost as a 2nd place because the Vortex was out of stock. Put it on a 300 Blackout AR with a 16" barrel. (no comments about the extra length not being needed please :^). It works like a charm. The low magnification with the IR picks up targets at all times of the day and night and when you put it on a low setting it works great at night in the snow. Loved it so much I bought a second one for a different AR. The only drawback is that it is easy to hit at 100m but hard to mark the groups so you will need a spotting scope to get a really precise zero. Now a huge fan!
