Osight Picatinny Mount OSP-157

The Osight Picatinny Mount OSP157 is a precisionengineered optic mount designed to provide a stable, elevated platform for micro red dot sights on Picatinny rail systems. Featuring a 1.57inch optical center height, it supports a lower 1/3 cowitness setup with standard ARstyle 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 steelreinforced base, the mount delivers a balance of strength, durability, and reduced weight. Dual crossbolts provide secure clamping force to maintain consistent alignment and zero under repeated use. Its compact, lowprofile 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.
