Classic
The Primary Arms Classic 24mm Mini Reflex is an open emitter pistol optic on the RMR footprint, offered with a 3 MOA Dot reticle in red. The window measures 0.63 x 0.91 in, and the aluminum housing measures 1.8 x 1.1 x 1.1 in and 1.4 oz. It runs on a CR2032 cell that requires removing the optic to change, and adds shake awake and night vision settings. Measured against the 311 pistol optics in the index, it lands about in the middle for weight (1.4 oz), about in the middle for window area (0.5733 sq in), and among the least expensive 10 percent for price ($160). It is one of 74 entries in the index that qualify as a RMR footprint optic. The closest listed comparison is Primary Arms SLX RS-10R, the same brand's RMR footprint optic, priced at $200.
