Primary Arms Miniature Reflex Sight Features The Primary Arms Miniature Reflex Sight is built around a 24x17mm lens larger than many micro red dots on the market giving the shooter a wider window for acquiring the dot quickly under stress. The RMR footprint it mounts on is one of the most widely supported standards in the industry so it drops onto a huge range of milled slides and adapter plates without a custom plate order. The 3 MOA green dot stands out clearly in bright daylight thanks to ten total brightness settings letting the shooter dial in the right intensity for an indoor range or a sunlit outdoor bay. Autolive technology senses motion and shuts the optic down after a period of stillness then wakes it instantly when the pistol moves extending battery life without sacrificing readiness. Housed in 6061 aluminum for durability the sight still weighs in at under an ounce so it adds negligible bulk to a carry or competition pistol. The lens is fully multicoated to resist scratching and fogging keeping the sight picture clear across changing weather and handling conditions. A bottom mounted CR2032 battery offers up to 40 000 hours of life on the medium brightness setting meaning the owner rarely has to think about a battery swap. Backed by a lifetime warranty as part of Primary Arms Classic Series lineup the Miniature Reflex Sight is a dependable affordable choice for everyday carry competition and home defense pistols.
