It will depend on what mount you use and what sights you are using. If I remember correctly the low mount would be a full cowitness and the higher would be lower 1/3. I recommend running a high mount like 2.2. I run the unity tactical high mount, I don’t have to bend my neck down, and there are iron sights included under the red dot in the mount. I also run the unity tactical flip to center magnifier mount. Flip to center is better for obvious reasons, but it can hold a 3x, 4x or like I’m running a 5x. I learned a long time ago that body mechanics and proper set up weapon systems make a huge difference in speed and fatigue. I can shoot with my head in its normal position, this allows me to be more aware of my surroundings, I can hold positive way longer, everything is better.
