I bought one to put on a "Burris RT6" to extend the range of the 1 x 6 power. The 2 x enhancer gives me double the magnification of the original scope, but has some limitations when using the "BDC" for further distances. It basically cuts the distance of the :BDC" hash marks in half. So in order to shoot a 200 yard target I have to hold on the 300 yard reticle (hash mark).
The "enhancer seems to be built very solid and the scope is fairly accurate in testing out to 200 yards.
