Osight X Raised Rail Mounted Adapter Features The Osight X raised rail mounted adapter is machined from 7075 aluminum and paired with a steel reinforced base for lasting durability under recoil. Two strong cross bolts clamp down on the Picatinny rail with ultimate clamping force keeping the mount locked in place through hard use. The 1.57 inch optical center height is specifically set up to provide a lower 1/3 co-witness with AR style iron sights. This lets shooters keep their dot and backup irons aligned in the same sight picture for quick target acquisition. Despite its rugged construction the adapter keeps a compact and slim profile that does not add unnecessary bulk to a rifle s top rail. It is compatible with the Osight X Olight Osight and other micro red dots that share the Ruggedized Miniature Reflex 407C or 507C footprint though it is not compatible with the Osight S. This broad compatibility makes it a versatile option for shooters running one of several popular micro red dot patterns. The combination of a raised height and rugged build makes this adapter well suited to duty competition and range use alike.
