Olight RMA-OSP091 OSight/OSight X Red Dot Mount

The Olight RMA-OSP091 is a purpose-built Picatinny adapter that brings the OSight or OSight X red dot onto any rail-equipped platform, from an AR-15 to a shotgun or pistol-caliber carbine. It's the piece that turns Olight's RMR/407C/507C-footprint reflex sight into a rail-mounted optic without hunting for aftermarket work-arounds.

This low profile 0.476" height mount achieves a precise 0.91-inch optical center height with Osight red dot installation. It's constructed from 7075 aircraft-grade aluminum with a steel-reinforced base for long-lasting durability, and two sturdy cross-bolts deliver exceptional clamping force on your picatinny rail, ensuring a secure fit.
