The AT3 Tactical RD-50 PRO Micro Red Dot can be purchased with different risers to achieve your desired height. With no additional riser, the optics centerline sits at 0.8", with the 0.83" riser, the centerline will be 1.43" (absolute co-witness), the 1" riser will provide you with a centerline height of 1.6" (lower 1/3 co-witness). This uses a brightness knob/dial with 11 different brightness settings. It does not have shake awake.
