New Device Makes Guns More Accurate | LiveScience
Opti-sight is a precision-milled half-triangle shape that replaces the traditional pistol gunsight. The design relies on subjective contours, an optics principle that explains how the subconscious mind fills in the blanks when the eye sees half of a familiar shape like a circle, square or triangle, Kraft says.
The rear opti-sight notch looks like an incomplete triangle sitting atop the gun barrel. When a shooter looks through the notch, the brain tells the eye where the missing triangle apex should appear, and that apex is the precise point of aim, Kraft says. "This triangular shape that I've created allows the brain to visualize concentric triangles whose imaginary apexes focus the shooter's attention on the exact target bullseye.
Sounds like a good concept. I doubt it would speed up some of the pro's we have on this board who are probably able to draw blindfolded and hit a center mass target at 10 yards 3 times in a row but if it can reduce the time it takes to become that good, that's a money saver.
