The 1.93 inch Reptilia DOT Aimpoint ACRO Red Dot Mount 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 1.93 DOT Mount attaches to any M1913 Picatinny rail to place the optical axis at 1.93 inches above the rail. 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.
