I have had one of the Gen 1 G2b XTR IIs in 5-25 on my 243AI for about 9 months now. Coming from a couple of Vortexs....this thing is incredible.

The glass is great, and the turrets phenomenal. The Zero Stop is perfect, and easy to set along with zeroing the turrets themselves. The illumination, while rarely used, is perfectly done, in my opinion. If I had to pick a nit, it would be the 8mils per rev as opposed to 10, but the newer Gen 2 SCR models have remedied that. Overall, I could not be happier.
