It takes a side-loading CR1632 cell, uses AutoLive motion sensing for 25,000 to 50,000 hours of runtime, is daylight-bright with night-vision settings, weighs 1.1 oz (31 g) in a 7075 aluminium housing, and ships with an M1913 Picatinny rail mount.\u003c\/p\u003e\u003cp\u003eThe R in the name is the important part: this sight uses the RMR and Holosun 507C footprint, which is the most widely cut pattern on optics-ready slides and the most widely supported by mount makers. That means it fits far more guns and mounts than a proprietary pattern would, and it fits them without an adapter plate stacking extra height into the sight line.\u003c\/p\u003e\u003cp\u003eThe side-loading battery is the other practical detail. The CR1632 changes without unmounting the sight, so a battery swap never costs you your zero — which on a small optic is the difference between a five-minute job and a range session spent re-zeroing.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHow It Compares\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThis is the value mini reflex sight with a plain 3 MOA dot.
