Osight XR Enclosed (RMR Footprint)

The Osight XR is the flagship of the Osight pistol optic line, a duty-rated enclosed-emitter red dot built on the RMR footprint with a feature stack aimed squarely at the Holosun 509T and Aimpoint ACRO. The headline is the 2/6+32 MOA multi-reticle system: shooters can switch between a 2 MOA dot, 6 MOA dot, 2 MOA dot with 32 MOA circle, 6 MOA dot with 32 MOA circle, or 32 MOA circle alone. Most enclosed competitors lock you into a single reticle SKU.

Power is unusual. The optic carries a built-in 89 mAh rechargeable lithium polymer cell, and the magnetic charging cover doubles as an 800 mAh power bank that snaps onto the housing for off-pistol top-ups. Osight rates runtime at 54,000 hours on the 2 MOA setting. A collapsible backup rear sight folds out of the housing when the dot fails, eliminating the need for a separate suppressor-height co-witness setup. Weight is 1.69 oz with overall dimensions of 1.91 x 1.18 x 1.16 inches.

Construction is enclosed 7075-class aluminum with IPX7 sealing against moisture, dust, and lint, the failure mode that kills open-emitter optics on carry guns. The RMR footprint covers full-size and compact pistols including most Glock MOS, SIG P320, and S&W M&P platforms. At a $299.99 street price, the XR sits roughly $250 below a Holosun 509T X2 and well under half the price of an Aimpoint ACRO P-2, making it the most aggressively priced enclosed pistol RDS with a multi-reticle system in 2026.
