No EXOS but have a 4-16x56 polar with exposed elevation with locking and capped windage. And yes it is heavy, but when mounted on my Tikka, it feels really nice.I have a 3-21 exos it checked all boxes for me, capped windage, locking elevation, good magnification range, perfect reticule (moa lrh 2ndfp), glass gives me that warm fuzzy feeling inside whenever I look through it. But with all scopes in this category it comes with a weight penalty. S&B makes good stuff...
