The DOT Mount by Reptilia is a lightweight, slim-line mounting solution for a variety of red dot optics. Machined from billet 7075-T6 aluminum with Milspec Type III hard anodized finish, the DOT Mount attaches to any M1913 Picatinny rail, and offers lower 1/3 co-witness with standard AR15-style back-up sights. Its spring-loaded nitrided steel clamp and mounting bolt simplify the installation process, and sit flush with the body of the mount for a low-profile, anti-snag design. Like all Reptilia products, the DOT Mount is 100% made in the USA and carries a full lifetime warranty against manufacturer defects. Additional heights and optic configurations coming soon!
