Description
The HS510C Lower 1/3 Spacer from Holosun HS510C is designed to raise compatible red-dot optics to a lower 1/3 co-witness height for improved sight alignment. It installs between the optic and its mount to increase the optical centerline height. This setup places the red dot above iron sights while still keeping them visible in the lower portion of the window. The result is a cleaner sight picture with better overall ergonomics on AR-style platforms. Constructed from lightweight aluminum with a durable finish, it is built for long-term use on Picatinny rail systems. Installation is simple and typically uses standard mounting hardware for a secure fit. It is also useful for optimizing compatibility with magnifiers and backup sight setups.
