OSight OSight R Features The OSight R uses an enclosed emitter design that shields the internal optics from dirt rain and debris a meaningful durability advantage over open emitter red dots in harsh field and duty environments. Its multi reticle pattern pairs a 2 MOA center dot for precise shot placement with a 65 MOA outer ring for fast target acquisition up close matching the reticle layout of other enclosed-emitter sights on the market today. The anodized black finish resists wear and corrosion through years of hard use on a duty or competition rifle. A Micro T1/T2 footprint means the OSight R drops onto a wide range of existing mounts and risers without requiring a proprietary adapter. Battery life is rated at an impressive 180 000 hours on a single CR2032 cell meaning the sight can be mounted and largely forgotten between battery changes. The sight s compatibility with common T1/T2 pattern accessories including risers covers and spacers gives shooters flexibility when building out a mounting solution for a specific rifle or carbine. Enclosed emitter optics in this class are prized for their ability to keep running even when exposed to moisture or impact and the OSight R is built to that same standard. For shooters looking for a rugged long-lasting red dot with a versatile reticle the OSight R delivers enclosed-emitter durability at an accessible price point.
