EOTECH EXPS3-2 with G43 magnifier on a flip mount gives you 1x and 3x capability. Glass is clear edge to edge on the EXPS3-2 window. Magnifier flips to the side cleanly. The hybrid setup zero held through a 300 round day.
EOTECHs EXPS3-2 with the G43 magnifier on a flip mount is the most versatile 0-300 setup Ive used. The 65 MOA ring with 1 MOA dot acquires fast. G43 magnifier is sharp enough to shoot good groups out to 200. Both products zero held through a class. Pricey but works.
