The Osight Picatinny Mount OSP‑157 is a precision‑engineered optic mount designed to provide a stable, elevated platform for micro red dot sights on Picatinny rail systems. Featuring a 1.57‑inch optical center height, it supports a lower 1/3 co‑witness setup with standard AR‑style iron sights, allowing a clear sight picture while retaining backup sight alignment. This height configuration offers improved visibility and faster target acquisition in dynamic use environments.

Constructed from 7075 aluminum with a steel‑reinforced base, the mount delivers a balance of strength, durability, and reduced weight. Dual cross‑bolts provide secure clamping force to maintain consistent alignment and zero under repeated use. Its compact, low‑profile design minimizes bulk while maintaining rugged performance. Compatible with Osight X, Olight Osight, and optics using the RMR/407C/507C footprint, the mount provides a reliable and stable solution for modern micro red dot configurations.
