I bought this to put on my new Volquartsen Scorpion.  The dot is sharp and the controls are excellent. I like the positive clicks on the windage and elevation adjustments.(They're subtle, but positive)  I can still use the open sights with the low fixed base mount. I've got 1000 rounds with the dot so far and the zero hasn't moved at all. Everything I hoped for and a great value.
