Overview
`Base | Picatinny | 1.8 in | FDE | AR-15 / AR-10` The American Defense Manufacturing Modular Base is a Picatinny-compatible optic mount base, designed to secure optics at a 1.8-inch height. This base utilizes a standard lever for toolless attachment and detachment, providing a repeatable zero. Its FDE finish offers a non-standard aesthetic compared to the most common black mounts. GPP build data shows this ADM Modular Base is commonly integrated into builds prioritizing quick-detach functionality for various optics. Builders on GPP commonly pair this base with red dot sights and magnifiers, often appearing in general-purpose AR-15 configurations.
