The EOTech OGL‑C‑T On‑Gun Laser combines a compact, rugged aluminum housing and a versatile aiming/illumination suite - with a visible green laser, IR aiming laser, and VCSEL‑based IR illuminator - all optically aligned on a shared bench for precise zeroing and consistent performance. Weighing roughly 8 ounces and sized similar to a deck of cards, it’s well‑suited for mounting on a rifle’s top rail or handguard without excessive bulk. A single CR123A battery powers the unit for up to 9 hours, while a Modlite‑style remote pressure switch gives ergonomic control from virtually any grip or mounting location. The IR illuminator offers adjustable beam divergence (spot to flood) via a sliding lever - letting operators tailor illumination quickly to their environment - and the dual visible/IR lasers make it equally effective for daylight aiming or night‑vision use. Designed with durability and field‑use ruggedness in mind, the OGL‑C‑T is a flexible, professional‑grade aiming/illumination module for a wide range of rifle platforms.
