I’ve used Aimpoint sights for years. In fact, two friends and I will crossbow hunt in South Africa this summer using the same ultra-durable sighting gear. The image above boosts my confidence even more. Aside from offering a single aiming dot of variable brightness, the battery life for most sights is about six years if left constantly in the “on” position. No wonder the sight still works. Here are the full details from OutdoorHub.

A fire on the night of February 18 drove Paul Riddell, his pregnant wife Katie, and their two kids out into the bitter cold in only their pajamas as they watched their home burn. The fire consumed nearly everything—photos, heirlooms, prized possessions—and anything that was not destroyed in the fire was left to freeze in the ice that was left over from the firefighters’ water hoses.

Weeks later, Paul rummaged through the remains of his house to see if there was anything worth salvaging. Among the ashes he found his three firearms. They were burnt to a crisp, but in a surprising turn an Aimpoint PRO red dot sight he had mounted on an AR-15 survived the inferno—and its dot reticle still functioned.
