The Gideon Optics Rock is an open emitter pistol optic on the RMR footprint, offered with a 45 MOA Circle + 3 MOA Dot reticle in red. The window measures 0.87 x 0.61 in, and the aluminum housing measures 1.77 x 1.26 x 1.04 in and 1.5 oz. It runs on a CR1632 cell that can be changed with the optic still mounted, and adds shake awake and night vision settings. Measured against the 311 pistol optics in the index, it lands on the heavier side for weight (1.5 oz), on the smaller side for window area (0.5307 sq in), and in the least expensive quarter for price ($200). It is one of 74 entries in the index that qualify as a RMR footprint optic. The closest listed comparison is Gideon Optics Alpha, the same brand's RMR footprint optic, priced at $200.
