I have one of the Ultralights as well and I tested three prototypes for SWFA as they were going through the BDC reticle development.

I really like this little scope and the one I have here has been on a good range of rifle varying from 22LR to 7.62x54R and it never hit me in the face with any of them. It is still less eye relief than I would want on a kicker, but aside from that, it seems perfectly serviceable.

The rimfire version with 50 yard parallax should be coming soon as is the BDC reticle. The BDC reticle is bolder than the plex, so it will be better in low light.
