Here is what 2Wild Guns says about the Osight X from Olight after using it for a year to determine how it holds up to regular use. Built with an RMR footprint, this red dot moves away from the tradition of hunting for coin cells by using an internal rechargeable battery instead. The device features a wide viewing window and a reticle that switches between a dot and a circle, though the reviewer spent twelve months making sure it actually worked before finally getting around to sharing his thoughts.

Constructed from aluminum alloy, the unit stayed in one piece despite high round counts and general wear. A notable claim involves the combined battery life of the optic and its magnetic charging cover, which is estimated to last twenty-six years. This should be plenty of time for most users, provided they do not lose the charging case during the first decade. To address skepticism about internal batteries, the manufacturer offers a lifetime warranty that covers the power cell, ensuring the optic remains functional well into the future.
