” Ever go to line up a target with your red dot or reflex optic only to find a blur of water, smudges or the dust cover? In tactical circles, this is what is called an occluded sight picture and if you don’t know how to handle it, it can mean curtains so check out some surprising details about what it takes to shoot anAR-15 or other rifle accurately with something else in your sight picture.
What Causes an occluded sight picture?
An occluded sight picture is an obstructed sight picture. To occlude means to stop or block a passageway. As it’s related to shooting, consider the pathway, tunnel or tube of a red dot or reflex optic or a rifle scope being blocked in the front (the muzzle end). The shooter can see the red dot, for instance, but the target is blacked out –at least from the dominant eye.
Shooting with an Occlusion
Thankfully shooting with an occlusion in your sight picture can be done with consistent accuracy by using the non-dominant eye. With both eyes open, the full obstruction that can’t be seen alone with the dominant eye can be viewed, making for an only partially-obstructed sight picture.”
