The Aimpoint Micro DOT Mount(TM) 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 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. Compatible with: AimpointA(R) - Micro R-1, Mfg: Reptilia Corp
