Dale,
I have had the 8-25 tactical for a few weeks now. Love the scope, it is clearer on 25x than my millet is on 10. It seems to have less of a problem with winking than the millet. I didn't like the millet because at 14x you just couldn't hold your position with out it blacking out. At 25x with the mueller I can get and hold a good sight picture.
Have not shot it enough to know the durability, but I'm not looking for any problems. Their warranty is good.
Just my 2cents.
Bobby
Oh, I got it from oneclickshooting.com,like inrut, for 159.00 free shipping and free sunshade. The sunshade did not fit but they are sending another one.
