I wouldnt worry about your line of sight being interfered with. If it really bothers you, you can rotate the Aimpoint in the mount but it will throw off your adjustment knobs. Hope that helpsallando said:I'm in the market for an aimpoint pro. I'm a lefty, am afraid that the switch assembly will interfere with my line of sight...
