Mine came in Tuesday, I haven't had a ton of time to play with it but I mounted it and shot it a little Tuesday and so far I'm extremely happy with it. There's no POI shift going from 100 yard zero on 4x and 25 yards on 1x. POI at 25 yards on 1x is about 1.5" low from POA as you'd expect from an optic on a AR zero'd at 100. Zero left to right change.
I get absolutely no fish eye effect on 1x and the FOV is great, appears to be a true 1x. Love the way the dot illuminates and how it's a generous 6moa at 1x and 1.5moa at 4x which allows for a reasonable level precision.
You essentially get the benefits of a RDS and an ACOG in one package that's roughly the same size as a TA11. It also looks amazing behind thermal on both 1x and 4x.
The only thing I did was remove the tenebraex ARD it came with and toss it in the box because I found it annoying seeing the honeycomb through the scope, especially on 1x. Unfortunately I never received my tier 1 operator so I don't really need it anyway.
