I used one at the Tulsa 3-gun championship match last weekend.
The only thing I didn't like was the eye relief isn't very forgiving. For $160ish with the mount I think its well worth it. I got it to try out 1-4 scopes to see if I'd like it enough for 3-gun to start using them instead of the Eotech.
So far I really like it. I placed 25th out of 40 somethin which ain't too bad for me especially with trying out new equipment.
