A few years ago I bought a Nikon M223 Laser IRT. I really like the scope with this feature. It works well, but for whatever reason Nikon discontinued them shortly after I bought mine. My only real complaints are its top magnification is 10x and the glass is just average. I would like to upgrade a bit to better glass and a little more magnification. The only other scope I am familiar with that has the rangefinder is the Burris Eliminator series. It is feature rich but I don't know about the glass quality. Who else makes one with a built-in LRF? Anyone here have a Burris and if so, what do you think of it?
