L'Antre Du Dingo takes a look at the AIMWIN PN320 red dot sight, an optic designed for real firearms but also used by airsoft players due to its quality. The sight is durable, made from 601 T6 aluminum, and features a CR 1632 battery with an advertised 10,000-hour life and a power-saving sleep mode. It offers three different reticle options and 11 intensity levels.
