Gideon Optics ROCK RMR-Compatible Red Circle Dot Sight | 3MOA/45MOA

The Gideon Optics ROCK is a compact, RMR-compatible red circle-dot sight designed for precise, rapid target acquisition. It offers a choice of red or green illumination and two reticle options: a single 3MOA dot or a 45MOA circle surrounding a 3MOA dot. The optic features a top-loading CR-1632 battery, waterproof construction, and a low-profile 1913 Picatinny mount for flexible installation.

Typical applications include everyday carry (EDC) on compatible pistols and competitive pistol or action shooting where a clear sight picture and quick acquisition are priorities. The sight’s small footprint and durable construction also make it suitable for extensive range practice and routine carry use.
