sight
Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision.
The resulting perception is also known as vision, sight, or eyesight (adjectives visual, optical, and ocular, respectively). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science.
I haven a very lightly used Ultrashot SM26008 red dot for sale. It has both red dot and green dot function. It has several brightness levels as well as reticles. Great optic for the price. Asking $80.
If this is in the wrong forum please feel free to move.

If a dovetail groove is machined right it will require a really tight pressfit to install or move, many rear sights rely on this technology for years just fine even surviving bumps and drops without budging. Nowadays dovetail groove sights like Novak are all coming with set screws. If the...
