Application & Background
The OP3 Micro SLS series includes multiple variants such as the OP‑RMD20CTS and OP‑RDM20R, each sharing the same compact SLS housing but differing in configuration. The OP‑RMD20CTS is engineered for modern optics‑ready pistols and PCC platforms, offering long battery life, a wide field of view and a rugged, waterproof construction. Its Docter‑footprint interface and low mounting height make it ideal for IPSC, PCC, tactical training and fast target transitions at short to medium distances.
