EOTECH G33 STS 3x Magnifier – Tan

The EOTECH G33.STS is a fixed 3x magnifier designed to extend the practical range of compatible red dot and holographic sights. Its Switch-to-Side (STS) mounting system allows rapid transition between magnified and unmagnified sighting while maintaining alignment with standard-height iron or optic sights. The unit features fog-resistant internal optics and is sealed for submersion to 33 ft (10 m), offering reliable performance in adverse conditions. The G33.STS ships with a protective case and the STS mounting system for quick detach and side-flip operation.
