The Theta Optics Compact II is a precision reflex sight engineered for airsoft operators demanding reliable target acquisition in variable lighting conditions. Its sealed metal housing protects internal optics while the CR2032 battery powers selectable red or green reticle modes across multiple brightness settings. Windage and elevation adjustments deliver consistent zero maintenance, and the standard 22mm RIS mounting system accommodates both high and low profile configurations for tactical flexibility. Rapid sight picture acquisition and smooth aiming performance make this sight ideal for CQB and mid-range engagements. Each unit ships with mounting riser, protective covers, hex key, cleaning cloth, battery, and user documentation—everything needed for immediate deployment.
